Stronger SEO metadata across every blog page

A focused SEO pass landed across the entire blog renderer with three concrete wins.

• Dynamic keywords — page metadata now pulls in your project's categories and tags for project-level pages, and article-specific keywords for article pages. Search relevance signals are richer and more accurate.
• Font and resource loading — fonts now ship with font-display: swap and preload hints, plus we added preconnect and DNS-prefetch entries for external resources. Better Core Web Vitals scores translate directly into better rankings.
• Image accessibility — article cover images got descriptive alt text, markdown images got lazy loading and responsive size hints. Both image SEO and accessibility improve in the same change.

None of these are visible features per se, but the cumulative effect on how Google sees your blog is real and measurable over time.
