# Languard Servers Manager — Frontend Design
## Purpose
A real-time game server management dashboard that gives admins instant visibility and control over their dedicated servers. The interface must feel like a mission control center — dense with live data, fast to react, and unambiguous in its state signals.
**Audience:** Server administrators managing game servers. Technical, task-oriented, frequently under time pressure (server crashed, player is cheating, need to restart now).
**Emotional tone:** Confident, precise, operational. Not playful, not corporate, not minimal-for-the-sake-of-it.
**Visual direction:** **Dark neumorphic command center** — near-black surfaces with soft extruded/inset shadows creating tactile depth, amber and orange accents cutting through like instrument panel lights, monospaced data glowing against dark backgrounds. The aesthetic of a physical control panel — buttons you can feel, displays that look back-lit, surfaces that have real mass.
**One thing the user should remember:** "I can see exactly what's happening and act on it immediately."

## Technology Stack
| Layer | Technology | Rationale |
|-------|-----------|-----------|
| Framework | **React 18** + **TypeScript 5** | Ecosystem, type safety, team familiarity |
| Build | **Vite 5** | Fast HMR, native ESM, minimal config |
| Routing | **React Router v6** | Standard, nested layouts |
| State (server) | **TanStack Query v5** | Server state cache, background refetch, optimistic updates |
| State (client) | **Zustand** | Minimal boilerplate, no providers, good for WS state |
| Forms | **React Hook Form** + **Zod** | Adapter-driven dynamic form generation from JSON Schema |
| Styling | **Tailwind CSS v3** + CSS variables | Utility-first with design tokens for theming |
| Charts | **Recharts** | Lightweight, responsive, sufficient for CPU/RAM/player time series |
| Icons | **Lucide React** | Consistent stroke style, tree-shakeable |
| HTTP | **Ky** (fetch wrapper) | Hooks, retry, typed responses |
| WS | Native WebSocket + custom hook | Minimal abstraction over browser API |
| Code quality | **ESLint** + **Prettier** + **tsc --noEmit** | Lint, format, type-check |
No UI component library (shadcn, MUI, etc.). Every component is purpose-built to the design system below.

## Design Tokens
### Color
Black, white, dark yellow, and orange. The palette mirrors a military-grade instrument panel — near-black surfaces, white text for readability, amber/yellow for data highlights and warnings, orange for primary actions and live indicators.
```css
:root {
/* ── Surfaces ──────────────────────────────────────────────
Dark neumorphism: surfaces are all near-black but subtly
differentiated by lightness. Neumorphic shadows (below)
create the illusion of physical depth — raised panels,
sunken inputs, extruded buttons.
*/
--color-base: #0d0d0d; /* deepest — page background */
--color-surface: #141414; /* panels, cards */
--color-elevated:#1a1a1a; /* raised panels, modals */
--color-hover: #1f1f1f; /* hover state on interactive surfaces */
/* ── Neumorphic shadow source ──────────────────────────────
Neumorphism requires two opposing shadows on the same
surface: a lighter shadow (simulating top-left light)
and a darker shadow (simulating bottom-right depth).
The source colors are derived from the surface itself.
*/
--neu-light: #1e1e1e; /* light shadow — 4-5% above surface */
--neu-dark: #0a0a0a; /* dark shadow — 4-5% below surface */
/* ── Text ───────────────────────────────────────────────── */
--color-text: #f5f5f5; /* primary — near-white */
--color-text-dim: #999999; /* secondary — timestamps, meta */
--color-text-muted: #555555; /* disabled, placeholders */
/* ── Accent — dark yellow / orange ──────────────────────── */
--color-accent: #d4940a; /* dark yellow — primary actions */
--color-accent-hover: #e5a61c; /* lighter on hover */
--color-accent-dim: #8b6210; /* muted accent for backgrounds */
--color-orange: #d45e0a; /* orange — secondary accent */
--color-orange-hover: #e56e1c; /* lighter on hover */
--color-orange-dim: #8b3e0a; /* muted orange for backgrounds */
/* ── Status ─────────────────────────────────────────────── */
--color-running: #d4940a; /* amber glow — server is live */
--color-stopped: #555555; /* gray — idle */
--color-starting: #d4940a; /* amber — transitioning (pulsing) */
--color-crashed: #cc3333; /* red — needs attention */
--color-error: #cc3333; /* red — error states */
/* ── Danger ─────────────────────────────────────────────── */
--color-danger: #cc3333; /* red — destructive actions */
--color-danger-hover: #dd4444;
/* ── Glow ────────────────────────────────────────────────
Status indicators use a subtle glow (box-shadow) to
simulate back-lit LEDs on a dark panel.
*/
--glow-amber: 0 0 8px 2px oklch(72% 0.15 80 / 0.4);
--glow-red: 0 0 8px 2px oklch(55% 0.20 25 / 0.4);
--glow-orange: 0 0 8px 2px oklch(65% 0.17 50 / 0.35);
/* ── Overlays ──────────────────────────────────────────── */
--color-overlay: oklch(8% 0 0 / 0.85); /* modal backdrop */
}
```
**Color rules:**
- **Black is the only background.** No white backgrounds anywhere. White is text only.
- **Amber (dark yellow) is the primary accent** — used for: primary buttons, active tabs, selected items, the "running" status dot, data highlight values.
- **Orange is the secondary accent** — used for: warning states, important metrics, secondary CTAs.
- **Red is reserved for danger** — crashed, error, destructive actions. Never decorative.
- **Gray is the neutral** — stopped status, disabled states, borders.
- No purple. No blue. No decorative gradients.
- Status dots glow via `box-shadow` — like back-lit LEDs on a physical panel.
### Neumorphic Surface Treatment
Dark neumorphism creates the illusion of physical depth through opposing light/dark shadows on near-black surfaces. Every interactive element signals its affordance through shadow direction:
```css
/* ── Raised (extruded) ────────────────────────────────────
Buttons, cards, metric tiles — things that sit above the surface.
Light shadow top-left, dark shadow bottom-right.
*/
.neu-raised {
background: var(--color-surface);
border-radius: var(--radius-md);
box-shadow:
4px 4px 8px var(--neu-dark),
-4px -4px 8px var(--neu-light);
}
/* ── Inset (sunken) ────────────────────────────────────────
Input fields, log viewer, search bars — things that go into the surface.
Dark shadow top-left, light shadow bottom-right.
*/
.neu-inset {
background: var(--color-base);
border-radius: var(--radius-sm);
box-shadow:
inset 3px 3px 6px var(--neu-dark),
inset -3px -3px 6px var(--neu-light);
}
/* ── Flat (flush) ──────────────────────────────────────────
Modal surfaces, overlays — flat on the surface, no shadow play.
*/
.neu-flat {
background: var(--color-elevated);
border-radius: var(--radius-lg);
box-shadow:
0 8px 32px oklch(0% 0 0 / 0.5);
}
/* ── Pressed ───────────────────────────────────────────────
Active/pressed button state — flips to inset.
*/
.neu-raised:active {
box-shadow:
inset 3px 3px 6px var(--neu-dark),
inset -3px -3px 6px var(--neu-light);
}
/* ── Accent raised ─────────────────────────────────────────
Primary action buttons with amber/orange fill.
Neumorphic shadows on a colored surface.
*/
.neu-raised-accent {
background: var(--color-accent);
color: #0d0d0d;
border-radius: var(--radius-md);
box-shadow:
4px 4px 8px var(--neu-dark),
-4px -4px 8px var(--neu-light),
0 0 12px oklch(72% 0.15 80 / 0.2); /* subtle amber glow */
}
/* ── Status LED ────────────────────────────────────────────
Status indicator dots with glow. Looks like a back-lit LED.
*/
.led-running {
background: var(--color-running);
border-radius: var(--radius-full);
box-shadow: var(--glow-amber);
}
.led-crashed {
background: var(--color-crashed);
border-radius: var(--radius-full);
box-shadow: var(--glow-red);
}
```
**Neumorphism rules for this project:**
- **Shadow intensity is proportional to interaction.** Buttons get full shadows. Decorative cards get lighter shadows. Flat info panels get none.
- **Never use borders with neumorphism** — shadows define edges, not lines. The only exception is focus rings for accessibility.
- **Inset for input, raised for output.** Form fields, log viewers, and search bars are sunken. Metric tiles, buttons, and cards are raised.
- **Pressed = inset.** When a raised button is clicked, it flips to inset shadows for tactile feedback.
- **Subtle, not extreme.** Shadow offsets are 3-4px, blur 6-8px. This is not the exaggerated neumorphism of 2020 — it's understated depth that makes the interface feel like physical hardware.
- **Glow replaces color fill for status.** Running servers don't just get a colored dot — they get a dot that glows, like a real LED indicator on a server rack.
### Typography
```css
:root {
/* Display — for page titles */
--font-display: "Space Grotesk", sans-serif;
/* Body — for most UI text */
--font-body: "Inter", sans-serif;
/* Mono — for logs, code, ports, PIDs, timestamps */
--font-mono: "JetBrains Mono", monospace;
/* Scale */
--text-xs: 0.75rem; /* 12px — badges, tags */
--text-sm: 0.8125rem; /* 13px — table cells, meta */
--text-base: 0.875rem; /* 14px — body, form labels */
--text-lg: 1rem; /* 16px — section headings */
--text-xl: 1.25rem; /* 20px — page titles */
--text-2xl: 1.5rem; /* 24px — hero metrics */
--text-3xl: 2rem; /* 32px — big status numbers */
/* Weight */
--weight-regular: 400;
--weight-medium: 500;
--weight-semibold: 600;
/* Line height */
--leading-tight: 1.25;
--leading-normal: 1.5;
--leading-relaxed: 1.75; /* for log blocks */
}
```
**Rules:**
- All data values (ports, PIDs, player counts, IPs) use `--font-mono`.
- Log viewer is entirely monospaced.
- Page titles use `--font-display`. Everything else uses `--font-body`.
- Never use font weight alone to differentiate — combine with size or color.
### Spacing
```css
:root {
--space-1: 0.25rem; /* 4px — tight internal gaps */
--space-2: 0.5rem; /* 8px — form field spacing */
--space-3: 0.75rem; /* 12px — compact padding */
--space-4: 1rem; /* 16px — standard padding */
--space-5: 1.5rem; /* 24px — section gaps */
--space-6: 2rem; /* 32px — page margins */
--space-8: 3rem; /* 48px — major separations */
}
```
**Rhythm:** 4px base unit. All spacing is a multiple of 4px. No arbitrary padding values.
### Borders, Shadows, Radii
```css
:root {
/* Radii — consistent, not excessive */
--radius-sm: 6px; /* inputs, badges, small buttons */
--radius-md: 10px; /* cards, panels */
--radius-lg: 14px; /* modals, overlays */
--radius-full: 9999px; /* status LEDs, pills */
/* Neumorphism handles edge definition — borders are rare.
Only use borders for: focus rings, table row separators,
and explicit dividers between sections. */
--border-subtle: 1px solid #222222;
--border-focus: 2px solid var(--color-accent);
}
```
**Note on neumorphic shadows + Tailwind:** The neumorphic shadow classes above cannot be expressed as single Tailwind utilities. Use CSS custom classes (`.neu-raised`, `.neu-inset`, etc.) defined in `globals.css` and reference them via `@apply` or direct class names in components. Tailwind utilities handle everything else (spacing, layout, typography, color).
### Motion
```css
:root {
--duration-fast: 100ms; /* hover states, toggles */
--duration-normal: 200ms; /* panel transitions, modals */
--duration-slow: 400ms; /* page transitions */
--ease-out: cubic-bezier(0.16, 1, 0.3, 1);
--ease-in-out: cubic-bezier(0.45, 0, 0.55, 1);
}
```
**Rules:**
- Motion is for state transitions, not decoration.
- Status changes (stopped→starting→running) use `--duration-normal` + `--ease-out`.
- No scroll-triggered animations. No parallax. No loading spinners with decorative motion.
- Log streaming has zero animation — lines appear instantly.
- Modals slide in from bottom or fade in. Never bounce, never spring.

```
- **Sidebar:** 56px collapsed (icons only), expands to 200px on hover/click. Icon + label for each section.
- **Header:** App name left, user dropdown right. Dark, fixed.
- **Footer:** Always visible — shows WebSocket connection status (connected/reconnecting/disconnected), number of running servers, app version. Critical for trust.
- **Content:** Scrollable main area. Min width 1024px.

## Page Designs
### 1. Login
Single centered card on dark background. No illustration, no hero, no marketing copy. The card itself is `neu-raised` — it appears to float above the base surface.
```

```
- No "remember me", no "forgot password" (single-host tool, admin manages users via CLI or initial setup).
- Failed login shows inline error with rate-limit countdown after 5 attempts.
- JWT stored in `localStorage`. On token expiry, redirect to login with a toast "Session expired".
### 2. Dashboard
A command-center overview. Not a marketing dashboard — dense, data-first. Neumorphic raised cards for metrics, inset panels for lists.
```

```
- **Summary cards:** Neumorphic raised (`neu-raised`). Large amber number on top, white label below. Monospaced numbers. Running count glows amber. Crashed count glows red (if > 0).
- **Server status list:** Clickable rows → navigate to server detail. Status dot is an LED with glow (`led-running`). Player count in `mono`. CPU is color-coded: <50% white, 50-80% amber, >80% orange-red.
- **Recent events:** Inset panel (`neu-inset`). Last 10 events across all servers. Crash events show red LED.
### 3. Server List
Full CRUD list with filtering and bulk overview.
```

```
- **Game filter dropdown:** Populated from `GET /games`. Inset input style (`neu-inset`).
- **[+ New Server]:** Raised accent button (`neu-raised-accent`). Amber fill, dark text.
- **Row actions (⋮ menu):** Start/Stop/Restart/Kill, Edit, Delete. Actions are context-aware — "Start" is disabled when running, "Stop" is disabled when stopped.
- **Sort:** Click column headers. Default sort: status (running first), then name.
- **Status column:** LED dot + short label. Amber glow = running, gray = stopped, red glow = crashed.
### 4. New Server Dialog
Modal overlay. Multi-step for clarity, not wizardry.

```
- **Game type selector:** Visual cards, not a dropdown. Each shows game name + icon. Only registered game types appear (from `GET /games`).
- **Config sections:** Dynamically rendered from `GET /games/{type}/config-schema`. Each section becomes a collapsible group. Fields generated from JSON Schema types (string → text input, integer → number input, boolean → toggle, enum → dropdown).
- **Sensitive fields:** Password inputs with show/hide toggle. Pre-generated values shown once in a dismissible callout after creation.
- **Port auto-fill:** Game port defaults from adapter's `get_default_game_port()`. RCon port from `get_default_rcon_port()`. User can override.
### 5. Server Detail

└─────────────────────────────────────────────────────────────┘
```
**Action bar:**
- `[Stop]` and `[Restart]` are `neu-raised` (default surface style).
- `[Kill ⚠]` is `neu-raised` with red text (not a red button — danger signals through color, not surface).
- Buttons press to `neu-inset` on click (tactile feedback).
- Action bar is fixed at top of content — always accessible.
**Metric cards:**
- Neumorphic raised (`neu-raised`). Updated in real-time via WebSocket (`type: "metrics"`).
- Player count shows `current/max` in mono font, accent color when > 0.
- CPU color-coded: <50% white, 50-80% amber, >80% orange.
**Tabs:** Rendered/hidden based on adapter capabilities:
| Tab | Condition | Source |
|-----|-----------|--------|
| Overview | Always | Server detail + recent events |
| Logs | Always | WebSocket `type: "log"` + `GET /servers/{id}/logs` |
| Players | `has_capability("remote_admin")` | WebSocket `type: "players"` + `GET /servers/{id}/players` |
| Config | Always (admin only) | `GET /servers/{id}/config` |
| Missions | `has_capability("mission_manager")` | `GET /servers/{id}/missions` |
| Mods | `has_capability("mod_manager")` | `GET /servers/{id}/mods` + `GET /mods` |
Tabs that the adapter doesn't support are simply not rendered. No disabled tabs, no "coming soon" badges.
### 5a. Server Detail — Logs Tab
```
┌─────────────────────────────────────────────────────────────┐

└─────────────────────────────────────────────────────────────┘
```
- **Entirely monospaced** (`--font-mono`). This is a log terminal, not a chat.
- **Container uses `neu-inset`** — the log area looks like a sunken display screen.
- **Level colors:** INFO = dim white, WARN = amber, ERROR = red. Color on the level tag only, not the whole line.
- **Streaming:** New lines prepend from top (newest-first) or append to bottom (oldest-first) — user toggle. Default: newest-first.
- **Virtualized list** for performance. Logs can grow to tens of thousands of lines.
- **Search** is client-side filter on loaded logs + server-side `?search=` for historical.
- **No auto-scroll lock** — if user scrolls up, stop auto-scroll. Resume when scrolled to bottom.
### 5b. Server Detail — Players Tab
```

└─────────────────────────────────────────────────────────────┘
```
- **Real-time:** Table updates via WebSocket `type: "players"`. No manual refresh.
- **GUID** column shows truncated GUID (click to copy full).
- **Ping** column color-coded: <100 green, 100-300 default, >300 amber, >500 red.
- **Actions:** Kick opens a small popover for reason input. Ban opens a popover with reason + duration.
- **Say All button:** Opens a message input. Sends `POST /servers/{id}/remote-admin/say`.
- **Viewer role:** Sees the table, no action buttons.
### 5c. Server Detail — Config Tab

```
**Dynamic form generation:**
- Config sections are collapsible panels, one per adapter section.
- Each section's fields are rendered from `GET /games/{type}/config-schema` (JSON Schema).
- JSON Schema → form field mapping:
- `type: "string"` → text input (or textarea if `format: "multiline"`)
- `type: "integer"` → number input (with min/max from schema)
- `type: "number"` → number input (step=0.1)
- `type: "boolean"` → toggle switch
- `enum: [...]` → dropdown select
- `type: "array"` → repeatable field group (for motd_lines, etc.)
- Sensitive fields (from `get_sensitive_fields()`) → password input with show/hide
- Field descriptions from JSON Schema `description` → tooltip on hover.
**Optimistic locking:**
- Each section stores its `config_version` from the last read.
- On save (`PUT /servers/{id}/config/{section}`), sends the version.
- On 409 Conflict: shows a diff dialog with "Your changes" vs "Current server values", with options to override or merge.
**Dirty state:**
- Unsaved changes show `(modified*)` on the section header.
- Navigation away from dirty form triggers an unsaved-changes dialog.
- `Reset Section` reverts to the last saved state.
**Preview:**
- `Preview Config` opens a modal with rendered config from `GET /servers/{id}/config/preview`.
- Each entry in the `label→content` dict is shown as a labeled code block. Monospaced.
- `Download ▾` gives individual file downloads from `GET /servers/{id}/config/download/{filename}`.

### Key Component Contracts
**`ConfigForm`** — the hardest component. Must handle:
- Dynamic rendering from JSON Schema (any game, any section)
- Sensitive field masking
- Dirty state tracking
- Optimistic locking (send `config_version` on save)
- 409 conflict resolution (show diff, allow override/merge)
- Validation errors from adapter (field-level, from Pydantic)
**`LogViewer`** — performance-critical:
- Virtualized rendering (react-window or similar)
- Newest-first or oldest-first toggle
- Level filter, text search
- Auto-scroll with manual-override detection
- Streams via WebSocket, paginated fallback via HTTP
**`ServerDetailPage`** — orchestrator:
- Resolves adapter from `server.game_type`
- Checks `has_capability()` to show/hide tabs
- Manages WS subscriptions for the server
- Handles status transitions in real-time (start → starting → running)
---
## State Management Strategy
### Server State (TanStack Query)
All API data uses TanStack Query with appropriate stale times:
| Query | staleTime | refetchInterval |
|-------|----------|-----------------|
| Server list | 30s | Background 30s (fallback for WS) |
| Server detail | 15s | — |
| Config sections | 5min | — (manual save) |
| Players | 0s | WS-driven |
| Logs | 0s | WS-driven |
| Metrics | 0s | WS-driven |
| Missions | 5min | — |
| Mods | 5min | — |
| Bans | 2min | — |
| Game types | 30min | — (rarely changes) |
| Config schema | 30min | — (tied to adapter version) |
**Optimistic updates** on:
- Server start/stop → immediately update status in cache, rollback on error
- Player kick/ban → immediately remove from player list cache
- Config save → immediately update config cache, rollback on 409 or error
### Client State (Zustand)
Only two stores — keep it minimal:
**`authStore`:**
```typescript
interface AuthState {
token: string | null;
user: { id: number; username: string; role: "admin" | "viewer" } | null;
setAuth: (token: string, user: User) => void;
logout: () => void;
isAdmin: () => boolean;
}
```
**`wsStore`:**
```typescript
interface WsState {
status: "connected" | "reconnecting" | "disconnected";
reconnectAttempts: number;
lastEventAt: number | null;
}
```
### URL State
Persisted in URL query params:
- Server list filters (`game_type`, `sort`)
- Log viewer filters (`level`, `search`)
- Ban list filters (`server`, `active_only`)
- Metrics chart time range (`from`, `to`, `resolution`)
---
## WebSocket Integration
### Connection Lifecycle
```
App Mount
│
├── Connect to ws://localhost:8000/ws/all?token=<JWT>
│ ├── On open: wsStore.status = "connected"
│ ├── On close: wsStore.status = "disconnected"
│ │ └── Auto-reconnect with exponential backoff (1s → 2s → 4s → ... → 30s)
│ ├── On error: wsStore.status = "reconnecting"
│ └── On message: dispatch to handlers
│
├── Subscribe to: ["status", "event"]
│
└── On server detail navigation:
└── Subscribe to: ["logs", "players", "metrics", "status", "event"]
for that specific server_id
```
### Message Dispatch
```typescript
// hooks/useWebSocket.ts
function handleWsMessage(msg: WsMessage) {
switch (msg.type) {
case "status":
queryClient.setQueryData(["servers", msg.server_id], (old) => ({
...old, status: msg.data.status, pid: msg.data.pid, started_at: msg.data.started_at,
}));
break;
case "log":
// Prepend to log cache (newest-first)
queryClient.setQueryData(["servers", msg.server_id, "logs"], (old) => ({
...old, logs: [msg.data, ...old.logs],
}));
break;
case "players":
queryClient.setQueryData(["servers", msg.server_id, "players"], msg.data.players);
break;
case "metrics":
queryClient.setQueryData(["servers", msg.server_id, "metrics"], (old) => ({
...old, current: msg.data,
}));
break;
case "event":
// Prepend to events cache + show toast for critical events
if (msg.data.event_type === "crashed") {
toast.error(`Server ${msg.server_id} crashed`);
}
break;
}
}
```
### Reconnection UX
- **StatusBar** shows connection state at all times: green dot = connected, amber spinner = reconnecting, red X = disconnected.
- During reconnection, all WS-driven data shows its last known value with a subtle "last updated X seconds ago" indicator.
- On reconnect, TanStack Query invalidates all server data to get fresh state.
- If JWT expires during WS connection, server closes the socket. Client detects 4xx on reconnect → redirect to login.
---
## Adapter-Aware UI Patterns
The frontend never hardcodes game-specific logic. It queries adapter metadata and renders accordingly.
### Capability Check Pattern
```typescript
// hooks/useCapability.ts
function useCapability(serverId: number) {
const { data: server } = useServerDetail(serverId);
const { data: gameType } = useGameType(server?.game_type);
return {
hasMissions: gameType?.capabilities.includes("mission_manager") ?? false,
hasMods: gameType?.capabilities.includes("mod_manager") ?? false,
hasRemoteAdmin: gameType?.capabilities.includes("remote_admin") ?? false,
hasBanManager: gameType?.capabilities.includes("ban_manager") ?? false,
};
}
// Usage in ServerDetailPage:
const { hasMissions, hasMods, hasRemoteAdmin } = useCapability(serverId);
// Only render tabs that the adapter supports
```
### Dynamic Config Form Pattern
```typescript
// lib/jsonSchemaToFields.ts
interface FieldDescriptor {
name: string;
label: string;
type: "text" | "number" | "boolean" | "select" | "textarea" | "password" | "array";
default?: unknown;
min?: number;
max?: number;
step?: number;
enum?: string[];
description?: string;
isSensitive?: boolean;
}
function jsonSchemaToFields(
schema: JsonSchema,
sensitiveFields: string[]
): FieldDescriptor[] {
// Walk schema.properties, map each to a FieldDescriptor
// Mark fields in sensitiveFields as type: "password"
}
```
### Game Type Card Pattern
```typescript
// Used in NewServerDialog and Dashboard
<GameTypeCard
gameType="arma3"
displayName="Arma 3"
capabilities={[...]}
selected={selectedGame === "arma3"}
onSelect={() => setSelectedGame("arma3")}
/>
```
Future adapters register themselves; the card list auto-populates from `GET /games`.
---
## Error Handling UX
| Scenario | UI Response |
|----------|-------------|
| API 401 | Redirect to login with "Session expired" toast |
| API 403 | "You don't have permission" inline message |
| API 404 | Empty state component with "Not found" |
| API 409 (config conflict) | ConflictDialog with diff + override/merge |
| API 422 (validation) | Field-level red highlights + error messages |
| API 429 (rate limit) | "Too many requests, try again in X seconds" toast |
| API 500 | "Server error" toast with retry button |
| WS disconnect | StatusBar indicator + stale data with timestamp |
| WS reconnect | Automatic; no user action needed |
| Server crashed | Toast notification + status dot turns red |
**No `alert()` calls.** All feedback uses toast (transient) or inline (persistent) patterns.
---
## Performance Budget
| Metric | Target |
|--------|--------|
| First Contentful Paint | < 1.5s |
| Time to Interactive | < 3s |
| Bundle size (gzipped) | < 250KB JS |
| CSS size (gzipped) | < 40KB |
| Log viewer render (1000 lines) | < 16ms per frame |
| WebSocket message processing | < 5ms per message |
**Techniques:**
- Vite code splitting per route (lazy `React.lazy` + `Suspense`)
- Virtual list for log viewer (react-window)
- TanStack Query deduplication (same query key = same request)
- Tailwind purge for minimal CSS
- Fonts: preload critical weights only (`Inter` 400/500/600, `JetBrains Mono` 400)
- No icon font — Lucide is tree-shaken SVGs
---
## Accessibility
- **Focus management:** Modals trap focus. Close on Escape. Return focus to trigger.
- **Keyboard navigation:** All interactive elements reachable via Tab. Action bar buttons have shortcuts (S=Start, X=Stop, R=Restart).
- **Color is not the only status indicator:** Status LEDs are paired with text labels. Logs use prefix tags (INFO, WARN, ERROR), not just color.
- **Contrast:** All text meets WCAG AA against its surface (4.5:1 minimum for body text).
- **Reduced motion:** Respect `prefers-reduced-motion` — disable transitions when active.
- **ARIA:** Live regions for WS status changes. `aria-label` on icon-only buttons.
---
## Toast System
Transient notifications. Stack in bottom-right.
| Type | Use | Duration |
|------|-----|----------|
| Success | Config saved, server started, mod enabled | 3s |
| Error | API errors, WS disconnect, validation failures | 7s (or dismiss) |
| Warning | Rate limited, high CPU, approaching memory limit | 5s |
| Info | Ban synced to file, mission uploaded | 3s |
Max 3 visible at once. Oldest dismissed automatically.
---
## Loading States
- **Route transitions:** Suspense boundary with a minimal loading bar at the top of the content area (not a full-page spinner).
- **Data loading:** Skeleton placeholders matching the layout shape of the loaded content. No spinners.
- **Actions:** Button shows inline spinner for duration of request. Disabled during request.
- **Initial load:** Dashboard shows skeleton cards → real data populates in place.
---
## Empty States
Every list/table has a designed empty state:
| Context | Empty State |
|---------|------------|
| No servers | "No servers yet" + [Create Server] button |
| No players | "No players connected" (dimmed, no action needed) |
| No missions | "No missions uploaded" + [Upload Mission] button |
| No mods registered | "No mods registered" + [Register Mod] button |
| No bans | "No active bans" (this is good news — no action needed) |
| No logs | "No log entries yet — server may not have started" |
---

### globals.css (neumorphic classes)
The neumorphic shadow classes live in `src/styles/globals.css` and are referenced by Tailwind components via `@apply` or direct class names. They cannot be expressed as Tailwind utilities (multi-shadow syntax):
```css
/* src/styles/globals.css — neumorphic primitives */
.neu-raised {
