…they're not useful
…only handled end of route
…l Wiki information + additional routing bugfixes
…ittle to no heuristics are needed - generated routes are now also much more stable
…sn't fit the screen - now the popup will draw somewhere where it has space without moving the map

Review comments at @packages/map/components/Markers/HoverPopup.tsx:
- Line 1: Format the new file containing the `HoverPopup` component with the
repository’s configured formatter so it passes the `oxfmt` check; keep the
implementation unchanged.
- Around line 52-54: Update the offset calculation in HoverPopup so the popup
body uses fitShift without the maxTipShift clamp; apply the rounded-corner limit
separately to the tip position so the body stays inside the map.
- Around line 83-84: Update the popup placement lifecycle around
placePopupInsideMap to recalculate placement on the map’s resize, moveend, and
zoomend events while the popup is open. Remove those event listeners when the
popup closes and during cleanup, preserving the existing ResizeObserver
behavior.
Review comments at @packages/map/lib/trainRoute.ts:
- Around line 192-203: Deduplicate consecutive resolved stops in computeRoute
before assembling legs: after resolving a station’s normalized name in the
station-resolution loop, skip it when it matches the previous entry in resolved,
then push only distinct consecutive stops. Preserve non-consecutive repeats and
the existing route assembly behavior.
Review comments at @packages/map/scripts/check-routes.mjs:
- Line 1: Format the route-check script with the project’s formatter so its long
lines conform to the formatting rules and the format check passes.
Review comments at @packages/map/scripts/generate-stations.mjs:
- Around line 114-117: Normalize each ring’s signed area and centroid
contributions by its winding before applying the outer-versus-hole sign in the
polygon centroid calculation. Apply the same correction in the MultiPolygon
branch, keeping holes subtractive so off-center holes do not pull the generated
station coordinate toward them.
- Line 241: Track failures from both the shape-fetch catch and the suppressed
server-failure handling during refresh, and abort before replacing either
catalog if any required request failed; do not publish incomplete station
records or classifications.

…f the output data is the same
Joins were stored as geometry only, and the client drew each one in the colour of the leg before it, so a join crossing track that isn't in the game was drawn green. Joins now carry their colour runs (same format as segmentColors), which the client applies, reversed for joins drawn backwards. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Hi! Because the map has been updated yesterday, I regenerated the train route data. After that, I observed some routing bugs still present, so I did a deeper dive into the algorithm and greatly simplified it and made it much more robust.
After I have done this, I saw that some of the map data such as stations needed to be manually updated, so I created a generator based on Wiki data for this info as well, as the wiki is updated extremely quickly whenever changes happen.
I have also removed a behavior where if the hover popup didn't fit the screen the map would move, which was incredibly annoying and was also mentioned in #152 (comment)
