/* For:Human — case page (built by scripts/build-work-pages.py from content/cases.json).
   Layout of the reference case pages, measured at 1440px: a full-width banner (video or image),
   a two-column info band in a 1280px container (client / project / tags on the left, context on
   the right, 112px above and below), then the case sections: image grids of 1–6 columns and
   video groups on a 20px gap, and text blocks centred at up to 1200px with 86px of air.
   Type is the For:Human scale (Inter). Class names match what src/forhuman-app.ts
   animates (.case-banner-section, .case-info-container, .case-section-list-wrapper). */
