/*
 * Crew17 — Design Tokens
 * CSS Custom Properties (Variables) als Single Source of Truth.
 *
 * Tailwind-CDN-Klassen bleiben primäres Styling-Werkzeug.
 * Diese Tokens definieren Werte, nicht Klassen — für:
 *   - Custom Components die kein Tailwind-Äquivalent haben
 *   - Doku / Referenz für das Design-System
 *   - Dark-Mode-Vorbereitung (light: → dark: Overrides)
 *
 * Mapping zu Tailwind:
 *   --color-primary       → indigo-500   (bg-indigo-500, text-indigo-500, …)
 *   --color-primary-dark  → indigo-600
 *   --color-cta           → zinc-900     (Linear-Signatur-Button)
 *   --color-bg            → white
 *   --color-bg-subtle     → zinc-50
 *   --color-border        → zinc-200
 *   --color-text          → zinc-900
 *   --color-text-muted    → zinc-500
 *
 * Verwendung: var(--color-primary) in Custom-CSS.
 * In Templates: direkt Tailwind-Klassen nutzen (bg-indigo-500 etc.).
 *
 * Migration der Komponenten auf Tokens: Sprint 11.5/11.6.
