Subject: [PATCH] bolt: optimize asset loading and script execution timing

- Added preconnect and dns-prefetch resource hints for Google Fonts.
- Switched to variable font weights for JetBrains Mono to ensure full coverage and efficiency.
- Optimized os2.html by invoking the availability check immediately rather than waiting for window.onload.
- Added comments explaining the performance rationale.
