   Load order: LAST (after tailwind.min.css and design-tokens-capifiq.css)

   This file contains:
     1. Font imports
     2. Base resets (html, body, links, selection, scrollbar, focus)
     3. Typography utilities (.cf-display-lg, .cf-mono, etc.)
     4. Layout utilities (.cf-container, .cf-section)
     5. Component classes (.cf-btn, .cf-card, .cf-pill, .cf-terminal, etc.)
     6. Keyframe animations

   Naming: all custom classes prefixed `cf-` to avoid Tailwind collision.
