+Editorial text (product descriptions, FAQs, pages) is maintained by hand in TYPO3 and can lag behind BusPro, e.g. an
+old price or a changed inclusion. The server instructions and the tool descriptions therefore tell the model that the
+structured trip fields of `search_trips` and `get_trip` override whatever the text says about dates, prices, pickups
+and inclusions.

 Every result carries the public `url`. Output is compact JSON with Markdown in the text fields.
 An empty result is `{"results": []}`. Invalid input produces a tool error the model can read.
