/* ==========================================================================
   orbits — design system stylesheet (CAT-98)
   ==========================================================================
   One stylesheet, embedded in the axum binary and served at /static/orbits.css.
   No external requests: system fonts only, no CDNs, no webfont hosts.

   Own the tokens, not the markup: templates use the class names listed here.
   If you need a new primitive, add it here — never inline styles in templates.

   Contents
     1. Design tokens            5. Post rows / feed
     2. Reset + base             6. Post detail + comments
     3. Header + navigation      7. Communities
     4. Buttons + forms          8. States: empty, error, flash
                                 9. Utilities + responsive
