Describe your issue

I'm working on a Laravel project that uses Vite. Everything was working great, but after adding a GeoJson file in a backend folder, Vite started running very slowly. Build runs changed from 400ms to 1m17s. Dev is also very slow.

This GeoJson file is unrelated to the frontend stuff and not referenced by any JS/CSS code.

Steps to reproduce

• Clone the repo https://github.com/emaia/laravel/tree/vite-bug
  (It's just a fork from laravel/laravel + 19mb geojson file)
• npm install, npm run build (runs slow)
• Delete the file database/seeders/payload/limites_munic_rj.geojson and rerun build. It runs fast.
• If revert @tailwindcss/vite to 4.0.9 or change css to import 'tailwindcss' source(none); it runs fast.
• Starting from @tailwindcss/vite v4.0.10, something happens.

Hey! We should probably ignore .geojson files by default. In the mean time you should be able to add this to speed things up:

@source not "./**/*.geojson";

Let me know if that works!

With @source not "../../**/*.geojson";, works!
(considering my app.css is in resources/css)

Tks!
