encre-css-vite + Gleam combination is slow

I'm playing with Gleam as a new language for frontend development (using Lustre framework).

I use Vite as bundler, with these plugins:

• @gleam-tools/vite
• encre-css-vite

But the hot reloading is slow. Last time I used unocss, it seemed fast enough.

I haven't narrowed down which one is the culprit. Will bring back UnoCSS and try.
