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.
