 This will:
 
-- Include all files from the `assets` directory except `temp.txt`
+- Include all files from the `assets` directory except `temp.txt` and the `temp` directory
 - Compress them using `gzip` and `zstd` (if beneficial)
 - For only files in `assets/immutable`, add a `Cache-Control` header with `public, max-age=31536000, immutable` (since these are marked as cache-busted paths)
 - Generate a `static_router()` function to serve these assets
