   base.css — shared structural layer + design-token contract.

   Every template loads this first, then overrides the tokens (and adds its
   own decorative styling) in theme.css. Themes change palette, typography,
   spacing and flourishes; this file owns the mechanics: layout scaffolding,
   the feed marquee, scroll reveals, the modal and accessibility.
