滝ノ上信号場 (45.21 km) and 楓信号場 (57.76 km) were both absent. OSM tags
them railway=signal / railway=junction with no place tag, so they fell
through both the railway filter and the place layer that had caught
滝ノ下信号場 and 十三里信号場.
滝ノ上 was a passenger station until its demotion to 信号場 in 2024.
Strip marks now carry the full object name; the km line underneath shows
the extracted Name when it differs. Labelling by the stripped root alone
was ambiguous where several objects share a name.

while the song is in progress.
- 274-transect.html — self-contained; carries its data in a script block,
fonts from Google Fonts, no other external requests. Opens by double
clicking. Same page as the published artifact.
- 274-route.json, 274-districts.json — the route line and the 23 大字
bands from the 250 m reverse-geocode sweep.
- 274-transect-build.py — re-reads the roster out of 274-dev.md and
rewrites the page's data block in place, leaving markup and script
alone. Run it after editing the table.
Everything under wip/ so the auto-wiki pipeline leaves it alone.
