/* ============================================================
   Gallery storefront — design system
   Principle: the site disappears and the artwork is the only
   thing with color. Wall-white ground, one warm accent, one
   serif voice. Nothing competes with a print.

   Motion rules (Emil Kowalski's framework):
   - only transform + opacity animate
   - custom ease-out curve; never ease-in on UI
   - UI transitions under 300ms; exits faster than entries
   - nothing enters from scale(0)
   - hover effects gated behind (hover: hover)
   - prefers-reduced-motion removes movement, keeps fades
   ============================================================ */
