Public Site Polish Pass

Navigation, metadata, typography, responsive behavior, content rendering, and release information received a site-wide cleanup without changing the established visual identity.

Polished

Synchronized the homepage directory with the global navigation and added About to the directory.
Improved horizontal navigation behavior on narrower screens and automatically centers the active section when needed.
Normalized active-route detection so nested pages highlight the correct section without false matches.
Added richer styling for CMS-authored images, code blocks, tables, figures, and captions.
Added favicon links and moved Google Fonts out of CSS @import into preconnected document links.
Added a crawl rule that keeps the private Admin interface out of search indexing.

Integrated

Homepage, footer, and 404 build readouts now pull from the newest deployed Update entry instead of carrying separate hard-coded version numbers.
Footer Last Updated and homepage system date now follow the deployed changelog automatically.
Added the canonical production site URL to Astro configuration.

Fixed

Updated the Admin patch-note form so version 0.7.0 creates the expected v0.7.0.md filename and displays a single v on the public changelog.
