No custom Planetiler profile needed after all — Maptool::HikingTrails runs osmium tags-filter r/route=hiking against the same .osm.pbf PmtilesBuilder already downloads per country for offline.pmtiles, then osmium cat -f opl (locations_on_ways=true) to get member-way geometry back as plain text, no separate node-id lookup table to build. No general OSM tool stitches a route relation into one line (routes are a semantic grouping, not a geometry type) — parse_opl does that walk itself, same as the Overpass-based click handler already does client-side. Kept pure/testable apart from the two osmium subprocess calls, mirroring OverpassPois.fetch vs .to_geojson. rake hiking:trails[pbf,out] to try it by hand against a real cached extract. Not wired into the actual offline build or rendering yet — still just a prototype, per TODO.adoc.
