   Only components confirmed absent from style.css: alerts, tabs,
   modal/dialog, pagination, stepper, timeline, dropdown, a
   filter/search bar, and semantic evidence/decision/recommendation
   card variants. Buttons, cards, badges, tables, forms and
   skeleton loaders already exist in style.css and are reused as-is.
   Load this AFTER style.css and tokens.css.
