/* Wan Dee Brown · interim portfolio · site.css v1.0 (2026-10-22)
   Brand: studio/brand/brand-guide.md (synced from Figma v0.20). Tokens below are the brand's light-mode roles.
   Layout: Material 3 window classes from the guide (Compact <600, Medium 600-839, Expanded 840-1199, Large 1200+),
   content max 1200, reading measure 600, section rhythm 96 / 64, 4px baseline.
   Motion is NOT in this file: site.js writes opacity/transform inline while scrolling, and only when JS runs and the
   visitor allows motion. With JS off every element simply shows (nothing here hides anything). */
