/* =============================================================================
   CASE STUDY STYLES  —  loaded AFTER /app.css
   -----------------------------------------------------------------------------
   Contains only what is specific to a case study:
     - case components (.back-btn, .meta-grid, .case-img, .card-box, .tradeoff-*, ...)
     - the deliberate case rhythm overrides (bigger h1 gap, section spacing, ...)
     - the resets below, which neutralise base-sheet properties that the case
       rhythm must NOT inherit.

   Design tokens, reset, shell and shared components live in /app.css ONLY.
   Generated from templates/case-template.html by scripts/split-case-css.cjs.
   ========================================================================== */

/* --- Rhythm resets: pin what /app.css would otherwise leak in ---
   Specificity must match the base rules, otherwise these lose. */
