@tailwindcss/vite still emits SOURCEMAP_BROKEN warnings in Nuxt/Vite builds

[murillodutt]

Summary

Using @tailwindcss/vite@4.2.2 with Nuxt 4.4.2 / Vite 7.3.2 still emits sourcemap warnings during build:

[plugin @tailwindcss/vite:generate:build] Sourcemap is likely to be incorrect ...

I know there is prior context in discussions/issues, but this remains reproducible in current versions.

Environment

• tailwindcss: 4.2.2
• @tailwindcss/vite: 4.2.2
• Nuxt: 4.4.2
• Vite: 7.3.2
• Node: 22
• pnpm: 10.12.4

Reproduction

1. Create fresh Nuxt 4 app with @nuxt/ui
2. Run pnpm run build
3. Observe repeated sourcemap warnings from @tailwindcss/vite:generate:build

Expected

Either:

• no warning, with proper sourcemaps generated, or
• documented non-warning path when sourcemap generation is intentionally partial.

Impact

• noisy CI/build logs
• strict warning policies treat this as release-blocking

If needed, I can provide a public minimal reproduction repository.
