Not able to Build [Vivaldi] themes

### Not able to Build [Vivaldi] themes
```sh
make
rm -rf ./dist
deno run --allow-env --allow-net --allow-read --allow-run --allow-write ./build.ts
error: Uncaught SyntaxError: The requested module 'npm:@catppuccin/palette' does not provide an export named 'variants'
import { variants as flavors } from 'npm:@catppuccin/palette'
^
at (file:///home/kaushiksahu18/vivaldi/build.ts:2:10)
make: *** [Makefile:6: build] Error 1
```

Run make and inspect the failing import in build.ts, where npm:@catppuccin/palette is expected to export variants. Check the installed palette package's available exports and update the build integration accordingly; done means make completes without the SyntaxError and produces the dist output.
