 * ui.css — DIRECTION A "Cupertino" component layer (ENH-GLOBWEB-UI-REDESIGN)
 * AnyAI component layer — Cupertino (Direction A). Swap landed 2026-07-04.
 * ----------------------------------------------------------------------------
 * Same CLASS names as the CP0 repo ui.css (drop-in replacement) — Cupertino
 * look: fully-rounded pill controls, solid deep-blue actions with a colored
 * drop-shadow, frosted glass (saturate + blur), tinted "wash" secondaries, an
 * ambient radial page glow, and SF-stack type. Consumes ONLY tokens.css vars,
 * with today's-dark fallbacks so a failed tokens load still renders.
