/* =============================================================================
   TikAPIs — design layer on top of Bootstrap 5

   Structure, in order:
     1. Tokens          colours, fonts, radii — the only place values are defined
     2. Base            body, typography, links
     3. Layout          containers, navbar, footer, wide (panel) layout
     4. Components      buttons, cards, forms, tables, badges — shared everywhere
     5. Marketing       hero, plans, docs — public pages only
     6. Panel           admin-only pieces that reuse the components above
     7. Utilities       small helpers

   Rule: a component is styled once, here. Templates use these classes and never
   inline styles, so there is a single place to change how anything looks.
