Context

PR #389 bumps 9 major npm dependencies in /web. The @tailwindcss/vite stable release (4.2.1) doesn't support Vite 8 yet — its peer dep is ^5.2.0 || ^6 || ^7.

Vite 8 support was merged on 2026-03-12 and is available in the insiders build 0.0.0-insiders.a4be983, but not in a stable release yet.

What was done

In PR #389, both tailwindcss and @tailwindcss/vite were temporarily pinned to 0.0.0-insiders.a4be983 to unblock the Vite 8 upgrade.

Action needed

Once a stable Tailwind CSS release ships with vite ^8 in the @tailwindcss/vite peer deps:

1. Update web/package.json:
   • Change "@tailwindcss/vite": "0.0.0-insiders.a4be983" → "@tailwindcss/vite": "^4"
   • Change "tailwindcss": "0.0.0-insiders.a4be983" → "tailwindcss": "^4"
   • Remove both //tailwindcss-insiders and //tailwindcss-note comment keys
2. Run npm install in web/
3. Verify all CI checks pass

How to check

npm view @tailwindcss/vite@latest peerDependencies --json

Look for "vite": "... || ^8" in the output.
