/* 歐可業務開發儀表板 — "Liquid Glass" visual system.
   Vanilla CSS, mobile-first, no libraries. Every surface is a translucent glass
   panel (backdrop blur + saturate, inner hairline highlight, soft ambient
   shadow) floating over slow-drifting colour orbs. Tokens live on :root so dark
   mode is one override block; text-vs-surface pairs keep WCAG AA (≥ 4.5:1).
   Browsers without backdrop-filter get an opaque fallback (see @supports). */
