CI / test-and-build (push) Successful in 47s
Root cause: osm-data.mjs emitted ways with 'out center' (no geometry) as a flat [lon,lat] labeled 'LineString'. Leaflet reads those as two invalid points and threw 'Invalid LatLng', which aborted the entire layer load loop in onMount -- so no layers rendered and the checkboxes all showed unchecked. Toggling then appeared to do nothing. Fixes: - osm-data.mjs: coordsFor/geometryFor now emit a proper Point for any flat [lon,lat] (from nodes / 'out center' ways) instead of a malformed LineString - MapView.svelte: isolate each layer's load + each feature's searchable build in try/catch so one bad feature/layer can't break all layers; skip invalid bounds in fitBounds - osm-data.mjs: preserve manifest entries it doesn't generate (e.g. dump layers from osm-dump.mjs) so data/osm-dump scripts don't clobber each other - scripts/test.mjs: add geometry-integrity checks (no malformed coords) Verified in a real browser: all 6 layers render, each toggles off/on independently (33361->0 overlays), and the Directions panel loads.
