Visual only — layout, behaviour, copy and functionality are untouched. Background - .ice-scene: fixed, z-index -1, pointer-events none. Navy base (#070b16 to #0c1426) in dark, pale (#f4f9ff to #e6f1fb) in light, four drifting glacier blobs (#38bdf8/#60a5fa/#818cf8, 30-60s transform-only loops), five glossy ice orbs (40-220px radial gradients with a highlight at 30% 25% and a blue shadow) placed so the glass blurs them, and an SVG feTurbulence grain at 4-5%. - prefers-reduced-motion stops the drift; phones get two blobs and two orbs fewer.

Radii: 24-28px cards/sheets, 14px inputs/buttons, pills for chips. Cards hover brighter + cyan rim + 2px lift, 180ms. Colour and type - Accent is glacier cyan (#38bdf8) to ice blue (#0ea5e9); progress bars and selected states use the gradient; the active sidebar item is a frosted highlight with a cyan rim. - Primary CTA: icy gradient — white to #bfe3ff with ink text in dark, deep blue in light (biased so the label sits on the darker half and keeps 5.6:1). - Leftover slate/black greys replaced with navy-tinted frost tokens. - Headings are semibold with tighter tracking. Screens - Dashboard: the sidebar is one tall inset rounded glass panel; deck cards are glass. - Gate: one centred glass card over the scene, orbs visible behind it. - Sheets/modals: glass over the dimmed, lightly blurred backdrop. - Study view: question card more opaque (.glass-solid); top bar and pager are slim glass pills. Perf: measured on a phone viewport with 4x CPU throttling. The animated blobs' filter: blur() was the whole cost (150ms vs 33ms per frame), so they are soft radial gradients with no filter now; idle 60fps, ~17ms median while scrolling.
