marvin dccf04349a Use platform nodes + route membership for bus stop clustering
Replaces distance-based clustering with route-membership grouping:
- download_osm.py: collect route_refs per stop node; use platform roles
  for bus stops, stop roles for rail stops
- prepare.py: carry route_refs through to master.gpkg
- render.py: group_by_route_membership() uses union-find to cluster
  same-name stops sharing at least one route into one marker; stops on
  disjoint routes are kept separate. No distance threshold needed.

Results: 786 bus platforms -> 465 markers (was 1610 -> 781).
Veksøvej: 2 platforms sharing routes 2A+5C -> 1 marker.
Peter Bangs Vej: 7 platforms on routes 10/21/22/4A/7A -> 2 markers.

marvin 0086d8a308 Copenhagen Phase 2: prepare.py merges + clips + colours -> master.gpkg
- prepare.py: merge per-mode OSM lines, resolve colours
  (GTFS route_color -> OSM colour tag -> keyed palette, robust to pd.NA),
  categorise buses (A/C/S/regular via regex), clip lines+stops to area,
  write master.gpkg layers (lines/stops/stations)
- download_osm.py: add stations query (public_transport=station /
  railway=station nodes+areas, out center) -> stations.gpkg with proper
  human-readable names + subway/light_rail mode tags for labelling
- verified: 135 lines (8 metro/16 s-tog/28 regional/83 bus), 90 named
  stations, zero NaN colours

marvin ac02320f1d Copenhagen Phase 1: scaffolding + area + OSM download
- pyproject.toml with all deps (geopandas, contextily, partridge, etc.)
- config/: area.json (3 OSM boundary relations), modes.yaml (subway/s_tog/
  light_rail/regional/bus, S-tog scoped to route=light_rail network=Takst),
  styling.yaml (zorder/widths/colours/palette/mask/labels)
- build_area.py: fetch 3 relations via OSM API, stitch rings, dissolve to
  area.gpkg/area.geojson (City Pass approximation)
- download_osm.py: per-mode Overpass (mirror+backoff, out geom + recurse for
  stops), writes {mode}.gpkg (lines+stops) + query text
- download_gtfs.py / gtfs_to_geopackage.py: stubs (blocked on Rejseplanen)
- data/ gitignored (regenerable); output/ tracked
