Root-fixes the opacity-modifier seed bug behind R10 S0: the theme colors were
bare `var(--x)` hex with no <alpha-value>, so `bg-accent/40`, `ring-accent/40`,
`border-border/60`, `text-muted/70`, … (~99 sites across 45 files) emitted no
CSS rule at all — latent no-ops. v4 implements the opacity modifier via
`color-mix`, so the modifier now works with the existing hex vars, no per-scheme
token duplication needed.
- `npx @tailwindcss/upgrade`: `@tailwind` directives → `@import "tailwindcss"`,
JS config → CSS `@theme` (colors, --font-sans, the z-index tokens preserved),
classname renames (rounded/shadow/blur scale, outline-none→outline-hidden,
ring→ring-2) across 56 files; PostCSS plugin → @tailwindcss/postcss,
autoprefixer removed (v4 prefixes for you).
- `@theme` → `@theme inline` (load-bearing): the color vars are redefined at
runtime under html[data-scheme]/[data-theme]; inline resolves them at the use
site so per-scheme opacity tints track the active scheme (the shadcn v4 pattern).
- Revert one codemod false-positive: it rewrote the English word "rounded" →
"rounded-sm" inside a releaseNotes.ts prose sentence.
Gate green: tsc(app+node) / eslint 0-err / prettier / vitest 79 / knip.
Verified in-browser: bg-accent/15 now computes a scheme-tracking color at 0.15
alpha across all 6 schemes × 2 themes; the hand-rolled glass border/shadow/
radius/backdrop-filter render unchanged under v4.
Prettier 3 (pinned), printWidth 100, double quotes — chosen to match the existing
hand-formatting and minimise reflow. This commit is ONLY the mechanical format pass
(`prettier --write`) plus the config/ignore/scripts, isolated so it never pollutes a
feature diff. Verified behaviour-neutral: typecheck, eslint (0 errors), and vitest
all green before and after. See .git-blame-ignore-revs — `git blame` skips this sha.
- linkify: bare http(s) URLs inside channel descriptions become clickable links
(new tab, rel=noopener noreferrer) — new lib/linkify.tsx, used in the shared
ChannelAboutContent so both the About overlay and the channel detail page get it
- Country flag: the flag EMOJI never renders on Windows/Chrome (showed the small-caps
'hu' fallback), so swap it for a real self-hosted SVG flag via the flag-icons package;
applies to the About overlay + the channel detail page
- The About overlay now shows the FULL channel About (description, external links,
country, language, topics, keywords) — the same content as the detail page's About
tab, via a new shared ChannelAboutContent component (reused by ChannelPage + AboutCell)
- AboutCell fetches the channel detail ON DEMAND on hover (shared [channel,id] react-query
cache with the channel page), so the list stays light; the overlay is interactive
(scrollable + clickable links) via a small hover-bridge, and closes on page scroll/resize
- Center the content: max-w-7xl -> max-w-[96rem] on the channel tables + header, so the
wider About table stays symmetric with the header (mx-auto handles the responsive centering)
- Topic chips are display-only for now; the future search epic makes them clickable
