/* =========================================================================
   bryanzane.com — shared editorial layer (v1)

   SOURCE OF TRUTH for the cross-page design system: tokens, base reset,
   nav chrome, footer chrome, buttons, and (later) the motion utilities.
   Loaded by /, /easyagent/, and /llmbench/ BEFORE each page's own
   stylesheet, so page CSS may override anything here.

   Rules of the layer:
   - Tokens only — no literal colors in component rules, so easyagent's
     body[data-profile] theming (incl. Frampton's dark inversion) keeps
     cascading over everything below.
   - Nothing page-specific. If only one page needs it, it does not belong
     here.
   - llmbench (separate repo) references this file absolutely as
     /shared/editorial.css — deploy this repo first when tokens change.
