tiles="OpenStreetMap" returned HTTP 403 "referer is required by tile usage policy" in the target browser — OSM graylists refererless requests and a karte.html opened via file:// sends no Referer. Esri's Canvas/World_Light_Gray base + reference layers need neither a key nor a Referer and keep the muted look. New MAP_TILES / MAP_TILES_LABELS / MAP_TILES_ATTR constants; generate_map adds them as explicit TileLayers. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
DRK Blutspende – Arbeitsorte: Dokumentation
Developer/maintainer documentation for the Arbeitsorte-Logger, a small desktop app that records blood-drive work assignments (date + city + postal code) and plots them on an interactive map.
Context: built as a personal tool for a single user, running locally on a Linux Mint laptop. Ease of use for a non-technical user is the primary design constraint. There is no server, no multi-user story, and no network dependency beyond geocoding and the map tiles.
