/* ============================================================
   gallery.css — GallerySection

   White background (color-surface-page). Standalone section —
   no ClayBackground dependency, no z-index stacking concerns.

   Three layouts:
   - Desktop (≥ 1360px):  3-col × 2-row grid
   - Tablet  (768–1359px): 2-col × 3-row grid
   - Mobile  (< 768px):   horizontal scroll row, fixed-size photos

   All spacing via token variables. Token mode handles
   desktop ↔ mobile value switches automatically.
   Only structural layout changes need explicit media queries.
   ============================================================ */


/* ============================================================
   GallerySection — outer container
   Vertical flex column. Children fill full width.
   Padding-top and gap both: space-layout-2xl (100px desktop / 44px mobile).
   overflow: hidden clips the mobile horizontal scroll row.
