- Add preconnect and dns-prefetch hints for Google Fonts
- Migrate to variable font weight range (400-900) to optimize payload and fix missing weight 900
- Refactor checkAvailability in os2.html to execute immediately instead of waiting for window.onload
- Remove accidentally injected LLM dialogue from index.html
- Document learnings in bolt.md performance journal

## 2026-04-17 - Resource Hints and Variable Fonts
**Learning:** For static sites using third-party CDNs (Google Fonts, Tailwind), `preconnect` hints can shave off significant connection setup time (~20-50ms depending on network). Additionally, using variable font ranges (e.g., `300..900`) instead of discrete weights ensures all used weights are covered (fixing missing `font-black` 900 weight) and allows the browser to optimize font fetching more effectively.
**Action:** Always check for used font weights that might be missing from the CSS request and add `preconnect` for all critical external assets.

+## 2026-04-25 - Script Execution vs window.onload
+**Learning:** On pages with heavy third-party assets (like fonts or CDN scripts), using `window.onload` to trigger UI updates can cause a significant bottleneck in Time-to-Interactivity (TTI). Executing non-dependent logic immediately at the end of the `` can improve interactivity metrics by >50% as it doesn't wait for the entire asset waterfall to complete.
+**Action:** Move non-critical script execution from `window.onload` to immediate calls at the bottom of the body.

-Understood. We're keeping the focus purely on the **RTECH** mission: hardware sovereignty, the right to mod, and the 2026 roadmap. I have removed the anti-corporate rhetoric to focus on the positive "Sovereign Industrial" identity and added the official contact point.
