Renderer modifications: a radar-specific darker ocean/earth/label palette and replacement of the font-family with a locally hosted Noto Sans Latin 400/600 (SIL OFL 1.1); other scripts/styles are pinned local copies. Map POI icons are not used by this low-zoom Leaflet style; radar node icons are existing inline SVG/CSS. Leaflet standard marker icons are hosted locally. UI fonts additionally use installed system font fallbacks.
All map data, renderer, styling, fonts and icons used at runtime are served by this station. No API key or external map request is needed.
