A park4night/OsmAnd POI export (e.g. a p4n2gpx area export) tags every waypoint with a category and a per-category color/icon in its <extensions> block, all of which was previously thrown away — every waypoint rendered as the same plain red dot, unreadable once a file has a few thousand of them. Maptool::Gpx now captures category/color/icon (waypoint_style), matched by namespace URI rather than local element name: a p4n2gpx file carries both <osmand:icon> and <locus:icon> side by side, and REXML strips prefixes from Element#name, so both report as just "icon" — matching on that alone was silently picking the (useless) Locus drawable path instead of the OsmAnd category key. Regression test added for this. On the map: waypoints are colored by category (falling back to the plain track color for anything uncategorized), a small hand-drawn icon set (public/js/icons.js's POI_ICONS, rasterized to SDF sprites at runtime) draws a glyph on top for the categories it covers, the points source is clustered so a dense export collapses into count bubbles instead of a solid blob, and a legend in the side panel lists whichever categories are currently visible. Splitting each file's GeoJSON into a lines source and a points source (rather than one mixed source with a geometry-type filter per layer) was needed for clustering, since MapLibre's cluster support only understands a source made entirely of points.
