Jarvis Playground v2.15.0 — Security, Speed & Polish

Version 2.15.0 is the biggest maintenance release yet. The AI Art Gallery's management endpoints now require server-verified authentication with rate limiting, the gallery loads pages server-side instead of pulling the entire 10,000-image catalog, and every one of the 17 nav-equipped pages now shares one canonical navigation with a working mobile menu.

Also in this release: real thumbnail generation for fast grid browsing, a live system status indicator on the homepage, category filter chips, reduced-motion accessibility support, fixed PWA icons, a regenerated sitemap with real dates, and the retirement of Vocal Separator (now part of Stem Separator). A data cleanup removed 4,810 broken placeholder entries from the gallery.
