   One stylesheet, no build step, no web fonts. Templates should reach for the
   classes defined here rather than inline `style=` attributes so spacing and
   colour stay consistent as pages are added.

   Structure:
     1. Tokens (light + dark)
     2. Base / reset
     3. Layout + app shell
     4. Typography
     5. Buttons
     6. Forms
     7. Surfaces: cards, choices, notices, pills
     8. Content: markdown, tables, code
     9. Utilities
