The map got beautiful: Liberty vector basemap.
Maps now render OpenFreeMap's Liberty vector style through MapLibre GL (keyless, no API keys, no accounts), giving crisp labels and soft Google-class cartography instead of raster tiles. Pins, popups, and the no-JS table are unchanged. Devices without WebGL fall back to plain OpenStreetMap raster tiles automatically. Every CDN asset stays SRI-pinned and the offline suite (now 180 tests) pins the style, the fallback, and the pins.
