🤖 **Summary:**
- **Root cause:** Font static assets were configured with unhashed
filenames (`[name][ext]`) while served with `Cache-Control: immutable,
max-age=31536000`. This caused Cloudflare edge nodes and client browsers
to permanently cache the older Latin-only font files from Sept 2026
under `https://www.ermnvldmr.com/ru/static/font/lato-400.woff2`,
ignoring the updated Cyrillic glyphs.
- **Changes:**
- Removed explicit `filename: { font: '[name][ext]' }` in
`packages/rsbuild-config/src/lib/config/rsbuild.ts` to enable Rsbuild's
default content-hashed font filenames (`[name].[contenthash:8][ext]`).
- Updated `services/www/rsbuild.config.ts` to remove hardcoded unhashed
font preload tags and configure Rsbuild's `performance.preload` to
automatically discover and emit hashed font `<link rel="preload"
as="font" crossorigin>` tags.
