fix(preview): theme the preview canvas via --muted token#66
Merged
Conversation
The outer canvas around the Slack chrome was hard-coded to #f4f4f4 (light) / #0e0f12 (dark), so brand presets like cyberpunk or ocean never reached it — the canvas stayed flat grey regardless of theme. Switch it to bg-muted so the active preset's muted color shows through (e.g. dark purple for cyberpunk dark, navy for ocean dark). The inner Slack frame intentionally still uses Slack's own canvas colors via isDark, since that surface is mimicking Slack itself. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
The outer preview canvas — the area framing the Slack chrome — was hard-coded to
bg-[#f4f4f4]/bg-[#0e0f12], so it stayed flat grey regardless of the active brand preset. Switch it tobg-mutedso presets like Cyberpunk and Ocean actually reach the canvas.Why
Reported when running the Cyberpunk preset in dark mode: the page background went deep purple but the surrounding canvas stayed neutral grey, breaking the themed look. The
--mutedtoken already varies per preset, so routing the canvas through it is the natural fix.The inner Slack frame (Message / Modal / App Home) intentionally still uses Slack's own canvas colors (
#1a1d21/ white) viaisDark, since that surface is mimicking Slack itself and shouldn't theme.Verified
