## Theming & CSS Variables

> **Wichtig für KI-Assistenten:** Das Theming-System verwendet ein eigenes Benennungsschema für CSS-Variablen. Bitte die Konventionen unten genau einhalten – generische Namen wie `--primary-color` oder `--color-blue` werden in diesem System **nicht** verwendet.

### Import

```stylus
// Vollständige Library (empfohlen):
@import 'oui-kit/stylus'

// Oder einzelne Teile:
@import 'oui-kit/theme'     // nur CSS-Variablen
@import 'oui-kit/lib'       // nur Mixins
```

```ts
// CSS (vorkompiliert):
import 'oui-kit/css'
```

### Benennungsschema CSS-Variablen

Das Schema folgt dem Muster: `--[level]-[style]-[state]`

**Level** (Farbpalette):
| Kürzel | Bedeutung | Beispiel |
|--------|-----------|---------|
| `n0` | Neutral (Grautöne) | `--n0-500` |
| `p1` | Primary (Markenfarbe, Blau) | `--p1-500` |
| `s2` | Secondary (abgeschwächt) | `--s2-fg` |
| `t3` | Tertiary (noch schwächer) | `--t3-bg` |

**Style:**
| Kürzel | Bedeutung | CSS-Eigenschaft |
|--------|-----------|----------------|
| `fg` | Foreground | `color` |
| `bg` | Background | `background` |
| `border` | Rahmen | `border-color` |
| `shadow` | Schatten | `box-shadow` |
| `radius` | Eckenradius | `border-radius` |

**State** (optional):
`hover`, `focus`, `active`, `disabled`

### Farbpalette

```css
:root {
  /* Neutral – Grautöne */
  --n0-50:  #f5f6f6;
  --n0-100: #e6e7e7;
  --n0-200: #d0d1d1;
  --n0-300: #aeb0b2;
  --n0-400: #7d8082;
  --n0-500: #6b6e6f;
  --n0-600: #5b5d5f;
  --n0-700: #4e4f50;
  --n0-800: #444546;
  --n0-900: #3c3d3d;
  --n0-950: #252527;

  /* Primary – Blautöne (Markenfarbe) */
  --p1-50:  #f3f7fc;
  --p1-100: #e7eff7;
  --p1-200: #c9dbee;
  --p1-300: #9abedf;
  --p1-400: #639ccd;
  --p1-500: #4385be;  /* ← Hauptfarbe */
  --p1-600: #2e659b;
  --p1-700: #27527d;
  --p1-800: #234569;
  --p1-900: #223c58;
  --p1-950: #17273a;
}
```

### Semantische Variablen

```css
:root {
  /* Vordergrund / Hintergrund */
  --fg: #0a0a0a;       /* Haupttextfarbe */
  --bg: white;          /* Haupthintergrund */

  /* Primär (Buttons, Links, Akzente) */
  --p1-fg: var(--p1-600);
  --p1-bg: var(--p1-100);

  /* Sekundär (Panels, Sidebar) */
  --s2-fg: var(--n0-600);
  --s2-bg: var(--n0-50);

  /* Tertiär (dezente Elemente) */
  --t3-fg: var(--n0-400);
  --t3-bg: var(--n0-100);

  /* Inputs */
  --input-fg: var(--fg);
  --input-bg: var(--bg);
  --input-border: var(--n0-200);
  --input-border-hover: var(--p1-300);
  --input-border-focus: rgba(66, 153, 225, 1);
  --input-shadow-focus: 0 0 0 3px rgba(66, 153, 225, 0.5);
  --input-radius: 4px;

  /* Buttons */
  --button-fg: white;
  --button-bg: var(--p1-500);
  --button-bg-hover: var(--p1-600);
  --button-bg-active: var(--p1-700);

  /* Links */
  --link-fg: var(--p1-700);
  --link-fg-hover: var(--p1-800);
  --link-fg-active: var(--p1-900);

  /* Schriftarten */
  --font: var(--font-sans);
  --font-sans: ui-sans-serif, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif;
  --font-mono: "JetBrains Mono", Menlo, Consolas, monospace;
}
```

### Dark Mode

Dark Mode wird über die Klasse `.dark` am `html`-Element aktiviert – **nicht** über `@media (prefers-color-scheme: dark)`.

```css
.dark {
  --fg: var(--n0-50);
  --bg: var(--n0-950);
  --p1-fg: var(--p1-400);
  --p1-bg: var(--p1-900);
  --s2-fg: var(--n0-300);
  --s2-bg: var(--n0-800);
  --t3-fg: var(--n0-500);
  --t3-bg: var(--n0-700);
  --input-border: var(--n0-500);
  --link-fg: var(--p1-300);
}
```

```vue
<!-- OuiDark setzt/entfernt die .dark-Klasse automatisch -->
<OuiDark :active="isDark" />
```

### Eigene Komponenten stylen (Stylus)

```stylus
// Eigene Komponente im Oui-Stil
.my-widget
  color var(--fg)
  background var(--s2-bg)
  border 1px solid var(--input-border)
  border-radius var(--input-radius)

  &:hover
    border-color var(--input-border-hover)

  &:focus
    border-color var(--input-border-focus)
    box-shadow var(--input-shadow-focus)
```

### CSS-Klassen-Modifikatoren

Modifikatoren verwenden einen **Unterstrich** als Präfix (nicht `-`). Das erlaubt saubere Vue-Bindungen:

```vue
<!-- Richtig: -->
<div class="oui-item" :class="{ _active, _disabled }">

<!-- Falsch (würde mit JS-Variablennamen kollidieren): -->
<div class="oui-item" :class="{ '-active': active }">
```

Interne Komponenten folgen dem Muster `oui-[name]` für Wrapper und `oui-[name]-[part]` für Unterelemente:

```html
<div class="oui-list">
  <div class="oui-list-item _active">...</div>
</div>
```

### Einheit `rex()`

Oui verwendet eine eigene Einheit `rex` – eine Mischung aus `rem` und `px`. `1rem = 16px`.

```stylus
// In Stylus-Mixins:
rex(16)   // → 1rem
rex(8)    // → 0.5rem
rex(24)   // → 1.5rem

// Padding/Margin-Shortcuts wandeln Zahlen automatisch um:
.demo
  padding-x 16   // → padding-left: 1rem; padding-right: 1rem
  margin-y 8     // → margin-top: 0.5rem; margin-bottom: 0.5rem
```

```ts
// In TypeScript:
import { rex, px } from 'oui-kit'
rex(16)  // → "1rem"
px(16)   // → "16px"
```

### Palette anpassen

Um die Markenfarbe zu ändern, genügt es, die `--p1-*`-Variablen zu überschreiben:

```css
:root {
  --p1-500: #e85d04;  /* Orange statt Blau */
  --p1-400: #f48c06;
  --p1-600: #dc2f02;
  /* usw. */
}
```
