/* =============================================================================
   FORJA — design system
   Phase 02

   One stylesheet for the whole platform. There is no framework.

   Structure:
     1. Reset
     2. Design tokens
     3. Base elements and typography
     4. Layout primitives
     5. Components
     6. App shell
     7. Utilities
     8. Motion, print, forced colours

   Rules this file follows:
     - Every colour is a token. No hardcoded hex outside the token block.
     - Every interactive element has a visible :focus-visible style.
     - Dark and light themes are equal citizens, not a bolt-on.
     - All motion respects prefers-reduced-motion.
     - Components never rely on a parent for their own appearance, so any
       component can be dropped anywhere without breaking.
