Straight ice: flat backdrop, crisp translucent panels, barely any gradients
The colourful multi-blob wash was too much and still didn't read as frosted glass. Replaced with a cleaner material approach: - Backdrop is now flat with a single faint top highlight (the only gradient left in it); the animated blobs and the four colour radials are gone. - Panels are crisper and more translucent: cards 62%, panels 66%, sidebar 64% (now flat, no vertical gradient), study chrome 68%, tab bar 70% — with a bright 1px edge (--glass-edge), a light-from-above sheen (--glass-sheen) and the inset top highlight. - Light mode is lighter: page #eef3fa pale ice, sidebar and cards frosted white; dark mode is a flatter, slightly lighter navy (#121a2c page, #1a2337 surfaces). - Key-gate glows toned right down to match. Contrast re-audited against the effective frosted backgrounds: 21/21 AA. Suites: deck chrome 15/15, deck fixes 15/15, final ux 12/12, key gate 49/49, install sheet 64/64, retry 14/14, zoom 6/6, security 8/8, pwa 16/16.
