- notes.js's ICON_LABELS wasn't extended for the shop_supermarket/
shop_convenience keys icons.js added — the note icon picker showed
the raw internal key as the title instead of a real label.
- Plugins.run mislabeled a malformed plugin.json as "plugin did not
print valid JSON" — a message written for bad script stdout, not a
bad manifest, since both paths shared one rescue.
- overpass_pois.rb's description_for joined raw OSM tag values with
"\n" — an operator/opening_hours tag with an embedded newline could
inject an extra line into the popup that gpx.js's formatDescription
(built for p4n2gpx's own well-formed lines) would render as its own
independent, legitimate-looking link. Tag values are stripped of
embedded newlines before joining.
