v0.9.1 — SEO & Performance Fixes

Small but impactful fixes based on our Okara AI audit:

- Faster page load — removed render-blocking font loading. Text now appears immediately with a fallback font while custom fonts load in the background.

- Better Google results — shortened the title tag so it no longer gets truncated in search results.

- Better social previews — completed Open Graph tags with absolute image URLs for cleaner link previews on X, Discord, and other platforms.
