/* ==========================================================================
   MiniCats SA — v4 design system
   --------------------------------------------------------------------------
   "Precision workshop": ink and steel neutrals, one safety-orange accent,
   engineering-drawing panels for technical figures. Self-hosted variable
   fonts (Inter for text, Space Grotesk for display and figures), no
   framework, no third-party requests.

   Layers, in order:
     1. Fonts & tokens (light, dark, legacy aliases)
     2. Base & typography
     3. Layout primitives
     4. Shell: topline, navbar, drawer, footer
     5. Components
     6. Forms
     7. Utilities, motion, print

   Page-specific styles live in pages/<name>.css and are loaded only where
   used. Anything two pages need belongs here instead.
