  box-shadow: 0 4px 20px rgba(0, 0, 0, 0.4);
}
```

### Buttons

**Primary:**

## 8. Naming Conventions

### Plugin-Prefixe

| Plugin        | Prefix    | Beispiel            |
|---------------|-----------|---------------------|
| Hub/Global    | `hub-`    | `.hub-header`       |
| Soundboard    | `sb-`     | `.sb-app`           |
| Radio         | (in `styles.css`) | `.radio-container` |
| Game Library  | `gl-`     | `.gl-container`     |
| LoL Stats     | `lol-`    | `.lol-container`    |
| Streaming     | `stream-` | `.stream-container` |
| Watch Together| `wt-`     | `.wt-container`     |

Neues Plugin: Eigenes 2–4 Buchstaben Prefix wählen.

### Klassen-Naming

```
.prefix-block              → Hauptcontainer
.prefix-block-element      → Kindelement
.prefix-block.active       → Zustandsmodifier
.prefix-block.disabled     → Disabled-State
```

- Hyphen-separated, lowercase
- Keine globalen generischen Klassen (`.card`, `.btn`) — immer mit Prefix
- Modifier als separate Klasse, nicht als BEM-`--modifier`

---

## 9. Layout-Regeln

### App-Shell

```
┌─────────────────────────────────────┐
│  Header (44px, --bg-primary)        │  ← .hub-header
│  [Logo] [Tabs...] [Controls]        │
├─────────────────────────────────────┤
│                                     │
│  Content Area (flex: 1, scroll-y)   │  ← .hub-content > .tab-panel
│                                     │
└─────────────────────────────────────┘
```

- Header: `44px` Höhe, `var(--bg-primary)`, `border-bottom: 1px solid var(--border)`
- Tab-Navigation: **Horizontal im Header** (keine Sidebar)
- Content: `flex: 1`, `overflow-y: auto`

### Grids

```css
.prefix-grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
  gap: 16px;
  padding: 16px;
}
```

- `minmax` Minimum je nach Inhalt: 88px (Sound-Cards), 220px (User-Cards), 280px (Game-Tiles)
- `gap: 16px` Standard, `gap: 3px` nur für dichte Grids (Soundboard)

### Responsive Breakpoints

| Breakpoint | Ziel        | Anpassungen                          |
|------------|-------------|--------------------------------------|
| `768px`    | Tablet      | Grid-Spalten reduzieren, Modal 90vw  |
| `480px`    | Mobile      | Flex-Direction column, Padding kürzen|

---

## 10. Do / Don't

### DO

- Alle Farben über CSS-Variablen (`var(--bg-card)`, `var(--text-muted)`)
- `var(--transition)` für alle Transitions
- `var(--font)` / `var(--mono)` für Font-Stacks
- `var(--radius)` / `var(--radius-lg)` für Border-Radius
- Solide Hintergründe für Content-Elemente
- `transform: translateY(-2px)` für Card-Hover
- Dunkle `rgba(0,0,0,...)` Shadows für Elevation

### DON'T

- `backdrop-filter: blur()` außer auf Modal-Overlays
- Farbige Glow-Shadows (`box-shadow: 0 0 Xpx var(--accent)`)
- Dekorative `linear-gradient` / `radial-gradient` Hintergründe
- `border-radius` über `6px` (außer `50%` Circles und `9999px` Pills)
- Hardcoded Farben für Hintergründe/Text/Borders (Ausnahme: Brand-Colors wie Steam `#66c0f4`)
- Font-Stacks direkt angeben (`font-family: 'Arial'`)
- Eigene Accent-Farben definieren — `var(--accent)` verwenden
- Globale Klassen ohne Plugin-Prefix

---

## 11. Theme-System

### Accent-Themes (global)

Wechselbar via `data-accent` Attribut auf Root-Element:

```html
<div data-accent="ember">   <!-- Standard: Orange -->
<div data-accent="amethyst"> <!-- Lila -->
<div data-accent="ocean">    <!-- Blau -->
<div data-accent="jade">     <!-- Grün -->
<div data-accent="rose">     <!-- Pink -->
```

Alle Accent-Varianten sind in `styles.css` definiert. Plugins greifen **nur** auf `var(--accent)`, `var(--accent-hover)`, `var(--accent-dim)` etc. zu.

### Plugin-Themes (optional)

Soundboard hat zusätzliche Farbthemes via `[data-theme="..."]`. Andere Plugins sollten das **nicht** nachbauen, sondern den globalen Accent nutzen.

---

## 12. Plugin-Template (Starter CSS)

Minimales Boilerplate für ein neues Plugin `example` mit Prefix `ex-`:

```css
/* ── Example Plugin ──
   Prefix: ex-
   Inherits all tokens from :root (styles.css)
   ────────────────────────────────────────── */

/* Container */
.ex-container {
  display: flex;
  flex-direction: column;
  height: 100%;
  overflow: hidden;
}

/* Toolbar */
.ex-toolbar {
  display: flex;
  align-items: center;
  gap: 8px;
  padding: 8px 16px;
  border-bottom: 1px solid var(--border);
  flex-shrink: 0;
}

/* Content Grid */
.ex-grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
  gap: 16px;
  padding: 16px;
  overflow-y: auto;
  flex: 1;
}

/* Card */
.ex-card {
  background: var(--bg-card);
  border: 1px solid transparent;
  border-radius: var(--radius);
  padding: 12px;
  cursor: pointer;
  transition: all var(--transition);
}
.ex-card:hover {
  background: var(--bg-card-hover);
  transform: translateY(-2px);
  box-shadow: 0 4px 20px rgba(0, 0, 0, 0.4);
}

/* Card Title */
.ex-card-title {
  font-size: 14px;
  font-weight: 600;
  color: var(--text-normal);
  margin-bottom: 4px;
}

/* Card Meta */
.ex-card-meta {
  font-size: 12px;
  color: var(--text-muted);
}

/* Empty State */
.ex-empty {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  padding: 48px 24px;
  color: var(--text-faint);
  text-align: center;
}

/* Modal */
.ex-overlay {
  position: fixed;
  inset: 0;
  z-index: 1000;
  display: flex;
  align-items: center;
  justify-content: center;
  background: rgba(0, 0, 0, 0.7);
  backdrop-filter: blur(4px);
}
.ex-modal {
  background: var(--bg-secondary);
  border: 1px solid var(--border);
  border-radius: var(--radius-lg);
  padding: 24px;
  max-width: 500px;
  width: 90vw;
  box-shadow: 0 8px 32px rgba(0, 0, 0, 0.5);
}

/* Responsive */
@media (max-width: 768px) {
  .ex-grid {
    grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
    gap: 12px;
    padding: 12px;
  }
}
```
