Till-JS 12ba2cf824 refactor(theme): remove custom theme editor and community themes
Remove unused custom theme functionality:
- Delete custom-themes-store.svelte.ts from shared-theme
- Remove ThemeEditor, ColorPicker, ThemeLivePreview components
- Remove CommunityThemeGallery, ThemeCommunityCard components
- Remove ThemeEditorPage, CommunityThemesPage
- Simplify ThemePage to show only built-in themes
- Remove editor and community routes from contacts app
- Update THEMING.md documentation

The built-in theme variants (default, ocean, forest, sunset, etc.)
provide sufficient customization. Custom theme creation was never
fully implemented and added unnecessary complexity.

# Central Theming System
Das zentrale Theming-System ermöglicht einheitliches Aussehen und Benutzereinstellungen über alle Manacore-Apps hinweg. Es besteht aus mehreren Schichten: Theme-Varianten, Light/Dark-Modus und Accessibility-Einstellungen.
## Architektur
```
┌─────────────────────────────────────────────────────────────┐
│ mana-core-auth │
│ ┌─────────────────────────────────────────────────────┐ │
│ │ user_settings (JSON-Feld) │ │
│ │ - theme: { mode, colorScheme, pinnedThemes } │ │
│ │ - nav: { desktopPosition, sidebarCollapsed } │ │
│ │ - locale: "de" │ │
│ │ - general: { startPages, sounds, etc. } │ │
│ └─────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────────┘
┌────────────────────┼────────────────────┐
│ │ │
┌────▼────┐ ┌─────▼────┐ ┌─────▼────┐
│ Todo │ │ Calendar │ │ Contacts │

└─────────┘ └──────────┘ └──────────┘
```
## Packages
| Package | Beschreibung |
|---------|--------------|
| `@manacore/shared-theme` | Theme Store, Types, Utilities, Konstanten |
| `@manacore/shared-theme-ui` | Svelte UI-Komponenten (ThemeSelector, ThemePage, etc.) |
## Theme-Varianten
Es gibt 8 vordefinierte Theme-Varianten:
### Standard-Varianten (PillNav)
| Name | Farbe | Icon | Hue |
|------|-------|------|-----|
| `lume` | Gold | sparkle | 47 |
| `nature` | Grün | leaf | 122 |

## Theme-Modus
```typescript
type ThemeMode = 'light' | 'dark' | 'system';
```
- **light**: Heller Modus
- **dark**: Dunkler Modus
- **system**: Folgt der System-Einstellung
## Color Tokens
Jede Theme-Variante definiert diese HSL-Farbwerte für Light und Dark:
```typescript
interface ThemeColors {
primary: string; // Hauptfarbe
primaryForeground: string; // Text auf Primary
secondary: string; // Sekundärfarbe
secondaryForeground: string;
background: string; // Seitenhintergrund
foreground: string; // Haupttext
surface: string; // Karten-Hintergrund
surfaceHover: string; // Hover-Zustand
surfaceElevated: string; // Modals, Dropdowns
muted: string; // Deaktivierte Elemente
mutedForeground: string;
border: string; // Rahmen
borderStrong: string; // Starke Rahmen
error: string; // Fehler-Rot
success: string; // Erfolg-Grün
warning: string; // Warnung-Orange
input: string; // Input-Hintergrund
ring: string; // Focus-Ring
}
```
### HSL-Format
Farben werden als HSL-Strings ohne `hsl()` Wrapper gespeichert:
```typescript
// Format: "H S% L%"
const gold = '47 95% 58%';
const darkBlue = '199 100% 18%';
// CSS-Verwendung
--color-primary: 47 95% 58%;
background-color: hsl(var(--color-primary));
```
## Store-Nutzung
### Theme Store
```typescript
import { createThemeStore } from '@manacore/shared-theme';
// Store erstellen
export const theme = createThemeStore({
appId: 'calendar',
defaultMode: 'system',
defaultVariant: 'ocean',
});
// In Komponente initialisieren
onMount(() => {
const cleanup = theme.initialize();
return cleanup;
});
// Zugriff auf State
theme.mode // 'light' | 'dark' | 'system'
theme.variant // 'ocean' | 'nature' | ...
theme.effectiveMode // 'light' | 'dark' (aufgelöst)
theme.isDark // boolean
// Aktionen
theme.setMode('dark');
theme.setVariant('nature');
theme.toggleMode(); // Light ↔ Dark
theme.cycleMode(); // Light → Dark → System → Light
```
### App-spezifische Primary Color
```typescript
export const theme = createThemeStore({
appId: 'memoro',
primaryColor: {
light: '47 95% 58%', // Gold
dark: '47 95% 58%',
},
});
```
### User Settings Store (Server-Sync)
```typescript
import { createUserSettingsStore } from '@manacore/shared-theme';
export const userSettings = createUserSettingsStore({
appId: 'calendar',
authUrl: 'http://localhost:3001',
getAccessToken: () => authStore.getAccessToken(),
});
// Laden
await userSettings.load();
// Zugriff
userSettings.theme.mode // Theme-Modus
userSettings.theme.colorScheme // Variante
userSettings.nav.desktopPosition // 'top' | 'bottom'
userSettings.locale // 'de'
userSettings.general.soundsEnabled
// Aktualisieren (speichert auf Server)
await userSettings.updateGlobal({
theme: { mode: 'dark' }
});
// App-spezifische Überschreibung
await userSettings.updateAppOverride({
theme: { colorScheme: 'nature' }
});
```
## Accessibility (A11y)
### A11y Store
```typescript
import { createA11yStore } from '@manacore/shared-theme';
export const a11y = createA11yStore({ appId: 'calendar' });
// State
a11y.contrast // 'normal' | 'high'
a11y.colorblind // 'none' | 'deuteranopia' | 'protanopia' | 'monochrome'
a11y.reduceMotion // boolean
// Aktionen
a11y.setContrast('high');
a11y.setColorblind('deuteranopia');
a11y.setReduceMotion(true);
a11y.resetAll();
```
### A11y-Optionen
**Kontrast:**
- `normal`: Standard (WCAG AA 4.5:1)
- `high`: Erhöhter Kontrast (WCAG AAA 7:1)
**Farbenblindheit:**
- `none`: Keine Anpassung
- `deuteranopia`: Grün-Blindheit (~6% der Männer)
- `protanopia`: Rot-Blindheit (~1% der Männer)
- `monochrome`: Graustufen
**Reduzierte Bewegung:**
- Respektiert `prefers-reduced-motion`
- Kann manuell überschrieben werden

## CSS-Integration
### Tailwind CSS
Die Themes werden als CSS-Variablen angewendet:
```css
:root {

--color-background: 199 100% 97%;
--color-foreground: 199 100% 18%;

.dark {
--color-primary: 199 98% 48%;
--color-background: 200 25% 7%;
--color-foreground: 0 0% 100%;
}
```
In Tailwind:
```html
<div class="bg-background text-foreground">
<button class="bg-primary text-primary-foreground">
Klick mich
</button>
</div>
```
### tailwind.config.js
```javascript
theme: {
extend: {
colors: {
background: 'hsl(var(--color-background))',
foreground: 'hsl(var(--color-foreground))',
primary: {
DEFAULT: 'hsl(var(--color-primary))',
