/**
 * Riterly App — Design System
 * Version: 2.0 — April 2026
 * Source: docs/branding/design-system/riterly-design-system.css
 * Cross-reference: BRAND_VISUALS.md, BRAND_VOICE.md
 *
 * THREE CONTEXTS:
 *   Context 1 — Marketing site (not covered here)
 *   Context 2 — App UI (dashboard, kanban, settings, admin overview)
 *   Context 3 — Editor environment (always dark, deep teal)
 *
 * TOKEN ARCHITECTURE:
 *   1. Brand tokens   — raw palette, defined once, never used directly in components
 *   2. Semantic tokens — usage-based layer, the ONLY layer components reference
 *   3. Compat aliases  — old token names forwarded to semantic layer (backward compat)
