Every page loaded Chart.js (~200KB), Moment and js-sha256 from a CDN whether it used them or not. Chart.js now loads only on the dashboard, Contacts and Multibyte, and js-sha256 only on Realtime, through a page_libs block in base.html. Moment is gone: its one call wrote to a #last-update element that no page renders, and that formatting is now done natively. The remaining base scripts stay at the end of <body>, so they don't block first paint.
The Mesh page loaded Leaflet 1.9.4, MapLibre GL 5.6.0, maplibre-gl-leaflet 0.1.4 and vis-network 9.1.9 from unpkg, and the login page loaded DM Sans and Outfit from Google Fonts, so neither worked on a LAN without internet. They are now vendored under static/vendor/ and static/fonts/ with their licenses and a README recording versions and sources (source-map comments stripped, since the maps aren't vendored). With nothing left on unpkg or Google Fonts, the CSP drops those hosts; the characterization golden is regenerated for that. package-data gains a fourth directory level for Leaflet's images.
Bootstrap, Font Awesome, Socket.IO, Chart.js and js-sha256 still come from CDNs; PRODUCT.md records that as the remaining offline gap.
