Tailwind v4's content scanner walks the entire project root by default
and emits a CSS rule for every class-shaped token it finds — including
literal class fragments quoted inside .planning report markdown and
docs/ design specs. The bracketed CSS-variable arbitrary-value form
combined with an opacity modifier (e.g. `bg-[var(--name)]/12`)
generates an escaped selector whose `\(...\)\/N` token sequence
crashes Turbopack's CSS parser with `Unexpected token Delim('.')`,
500-ing every page that imports globals.css.
The crash:
./src/app/globals.css:1853:27
Parsing CSS source code failed
1852 | .bg-\[var\(...\)\]\/12 {
> 1853 | background-color: var(...);
| ^
Three coordinated changes:
- Add `@source not "../../.planning"` and `@source not "../../docs"`
to globals.css so the scanner skips planning + docs trees. Stops
fixture-style class names in research/audit reports from poisoning
the generated CSS.
- Migrate `bg-[var(--dracula-*)]/N` / `ring-[var(--dracula-*)]/N` in
target-card.tsx to the Tailwind v4 parenthesised shorthand
`bg-(--dracula-*)/N` / `ring-(--dracula-*)/N`. The shorthand emits
a clean selector that LightningCSS parses cleanly. Per the Tailwind
v4 upgrade guide, the bracketed form is deprecated for CSS
variables.
- Replace `shadow-[0_0_0_1px_var(--dracula-green)]/20` in
consistency-strip.tsx with `shadow-[0_0_0_1px_color-mix(in_oklab,var(--dracula-green)_20%,transparent)]`.
The arbitrary shadow with opacity modifier hits the same parser
issue; encoding the alpha directly in the value via color-mix
removes the modifier and keeps the visual identical.
Verification: `pnpm dev --port 3030` then `curl -sI /auth/login` ->
HTTP/1.1 200 OK (was 500). Zero CSS parse errors in the dev server
log. Affected tests (targets + api-handler + api/version) still pass
(31/31).
