/* ==========================================================================
   PROJECTS INDEX PAGE (/projects), Features + Archive (2026-09-30)
   Four tiers: phone < 600, tablet 600 to 1023, laptop 1024 to 1439,
   wide 1440+. Plan: docs/redesign/projects-cards-plan-2026-09-30.md.
   Brief: docs/motion-zen.md section 6b "Projects cards revamp".
   Live work: feature cards with a framed desktop screenshot and a phone
   on a tinted mat. The archive: Role Ledger rows that open in place to
   the full story, with the project's drawing on the same mat. The filter
   is the Stretch Rail (components/stretch-rail.css); buttons are the pill
   family (components/buttons.css). Materials come from the shared surface
   tokens, so light is clay and dark is glass without theme rules.
