/* =========================================================================
   work.css — portfolio / case-study stylesheet (2026-09-16 portfolio redesign)
   -------------------------------------------------------------------------
   Loaded AFTER css/home.css by index.html (for the Selected Work section)
   and by every work/*.html case study. It never touches home.css tokens —
   it only reads them (--ink, --paper, --line, --ease, --font, --nav-h…).

   Contents
     1. Homepage work index      .wk-*     (rendered by renderHomeWork())
     2. Device frames            .frame-*  (CSS-only browser / phone mockups)
     3. Case-study pages         .cs-*     (shared skeleton + per-page themes)
     4. Responsive + motion

   Design intent: Apple-product-page restraint. Large type, generous space,
   subtle borders, no accent color at the studio level — each project's own
   palette shows up only inside its case study (via [data-theme] tokens).
