/* about.css — «О магазине» (about.html), build P6 of the 017 demo, 27.09.2026.
   Map: logic/NEW_MAP_4.md §11 B1–B5. A story page off the menu (R12, R13): ice on top, white in the middle, the blue sea at the
   bottom — the page gets deeper as it scrolls (ice → white → paper → cobalt → sea → footer); a wave on every join.
   Smooth like S02: Lenis and the reveals of app.js. Motion: transform and opacity only. Colours: tokens of css/base.css and the
   ice of DESIGN.md «Стиль категорий» (#dfeaf7, #e7eef6). */
