Pelias hides the 'category' field from API responses unless the caller filters by categories=... explicitly — a default intended for keyword search that strips category metadata from address queries. Patch the Pelias API's geojsonify_place_details.js so the category array is returned on every feature (food, retail, transport, …), mounted into the container as a read-only volume override. Rewrite category-map.ts to map Pelias' OSM taxonomy to our 7 PlaceCategories using a priority-ordered list so a restaurant tagged ['food','retail','nightlife'] resolves to 'food' (the most specific), not 'shopping'. Verified with Konstanz test queries: Konzil Restaurant → food Bahnhof Konstanz → transit Physiotherapie-Schule → work MX-Park → leisure Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

/**

* Maps Pelias categories (OSM taxonomy) to our 7 Places categories.

|
* Pelias' openstreetmap importer tags venues with categories from its
|
|
* built-in taxonomy (food, retail, transport, health, education, …).
|
|
* We collapse those into the simpler Places enum:
|
|
*
|
|
* home · work · food · shopping · transit · leisure · other
|
|
*
|
|
* A venue can have multiple Pelias categories (e.g. a restaurant is
|
|
* tagged `['food', 'retail', 'nightlife']`). We pick the most specific
|
|
* one in priority order rather than the first — a restaurant should be
|
|
* "food" even though "retail" also matches.
