From 5d0559212b98fbc2ec510cb18067cf3312be8a68 Mon Sep 17 00:00:00 2001 From: Martin Dvorak Date: Thu, 8 Oct 2026 09:20:22 +0000 Subject: [PATCH] Straight ice: flat backdrop, crisp translucent panels, barely any gradients MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. --- README.md | 30 ++++---- app/globals.css | 177 +++++++++++++++++++----------------------------- 2 files changed, 84 insertions(+), 123 deletions(-) diff --git a/README.md b/README.md index 2600e53..259cf1c 100644 --- a/README.md +++ b/README.md @@ -112,10 +112,11 @@ no database, no data leaving your machine except the requests you send to Ollama list with per-folder counts, Settings/Dark mode pinned to the bottom).
