/* ==========================================================================
   The Battin Front: shared design system (css/tbf.css)

   Loaded on every public page AFTER css/styles.css and any page stylesheet,
   by the head partial that tools/sync-partials.ps1 stamps into each page.
   The internal tools (knowledge-base.html, metassist.html, ...) do not load
   it, so nothing here can change them.

   Layout of this file:
     1. Tokens (light default, dark via system or the manual switch)
     2. Base
     3. Header: nav, tabs, menu, sub-nav
     4. Alert strip
     5. Components: buttons, pills, cards, tables, forms, town picker
     6. Broadcast 5-day card (dark in both themes)
     7. Home page
     8. Footer
     9. Legacy bridge: maps css/styles.css onto the tokens
    10. Page bridges (weather, climatology, space weather, maps, chase log)
    11. Reduced motion

   Dark values come from the Hub's stylesheet; the light theme uses the same
   TBF blue with cool greys. The logo gradient (--brand-grad) is for follow
   and subscribe buttons only.
