The application no longer knows what it looks like. It imports one stylesheet and
mounts one provider; every colour, surface and radius lives in `src/workspaces/theme`.
Proven both directions, because either alone would be worthless:
Duck renders IDENTICALLY to before — checked against screenshots taken before
anything was touched, not asserted.
Plain renders as white with black ink, no component edits — panels turn white, the
teal avatar turns black, the grid fills vanish.
── What moved ──
`globals.css` held three unrelated things: Tailwind wiring, the token contract, and
the Duck brand's hex values. Split along those seams. `base.css` is structure and
names no colour; a theme file is values and nothing else, scoped to
`[data-theme='<id>']`. Adding a theme is a CSS file plus one registry line.
Light and dark are separate themes rather than a mode — the owner's call, and it
removes a concept from the app. Each is written out in full: a theme that only makes
sense as a diff against another cannot be authored by a stranger or sold to a
customer. `.dark` survives only as a per-theme flag, because 396 `dark:` utilities in
33 components resolve against it; retiring those retires the flag.
The `duck-*` utility names are kept for now and pointed at neutral variables, so a
non-Duck theme can define them sensibly. Renaming 1,470 occurrences in the same commit
as the extraction would make any visual difference impossible to attribute. Worth
recording that `duck-dark` was never a brand colour — `#14532d` in light, near-white
in dark, used by 946 components to mean "text". It is `--ink` now.
Surfaces are complete CSS values rather than HSL triplets: `--panel-bg` has to be able
to be a gradient or an image, or the glass the app already has would be unthemeable.
The old provider is a re-export, so its six call sites are untouched and the
extraction stays one variable.
── Bug found by the Plain theme ──
`useThemeSync` stamped the server's `appearance.colorMode` over the local theme on
every load, so choosing Plain and reloading silently reverted it. Diagnosed by asking
the page what it was wearing rather than reasoning: `stored` said `duck-dark` when the
script had written `plain`. The server value is now a starting point for a browser
that has never chosen, not a continuous instruction.
── Tools ──
Two, both of which lied to me before they worked. The snapshot script photographed
light twice and called it a clean run (one browser context, accumulated init scripts);
it now warns when a light/dark pair is identical. The preview server returned the
shell for missing assets, so the logo and wallpaper vanished and read as regressions
in the comparison — it falls through to upstream now.
Dead Tailwind v3 residue deleted: `components/ui/tailwind.{config.ts,css}`, referenced
by nothing, with content globs pointing at a directory that does not exist.
── Not done, deliberately ──
`THEMES-NOTES.md` has the full list. The headlines: the reference repo has not been
read, so the switching mechanism is deliberately the dumbest thing that works; the
wallpaper, panel radius and logo are still component-owned and Plain proves it; and
~985 raw Tailwind palette usages remain, worst in Soulseek.
tsgo clean.

The themes work moves every colour out of the components and into a token layer, and
the entire value of that is being INVISIBLE. Nothing here could have told us whether
that held: the tests do not render, and comparing two screens from memory an hour
apart misses exactly the things this can break — a border colour, a radius, one mode
of two.
Eight routes, both colour modes, against the running app. Byte comparison rather than
a pixel-tolerance diff: a false alarm costs opening two images, a false all-clear
costs the refactor.
The first version was worthless and looked fine. It reused one browser context and
added an init script per mode — Playwright ACCUMULATES those, so the dark pass ran the
light script too, and the class toggle after `goto` was undone by the provider's own
effect. Six of eight routes came out byte-identical in light and dark, which reads as
a clean run. A context per mode fixes it, the class is asserted after settling rather
than before, and identical light/dark pairs now print a warning instead of passing
quietly.
Verified rather than assumed: 15 distinct images of 16, every route differs between
modes, and one was opened to confirm it is the authenticated app and not eight
variations of an error boundary.
Baselines are gitignored — 7MB of machine-specific PNGs. Regenerate with the script.
