/*
  Destination: C:\Lensari\Lensari\claude-hq\drafts\gallery-site-v1\shared\site.css
  Purpose: shared components for every lensari.ca page: base rhythm, toolbar,
           footer, buttons, circuit traces, portal-card, product-card.
  Ownership: FOUNDATION OWNER ONLY. Page builders link (after tokens.css),
             copy the markup snippets from README-foundation.md, never edit this file.
  Register: derived from the Cameron-ratified Poshmark pilot (gallery-pilot/poshmark).
  Motion: v1 static discipline (constitution 6.1). Hover = lit trace, never a
          moving pulse. All non-essential motion is behind prefers-reduced-motion.
