`POST /v1/trip-templates`

Saves a trip as a trip template (Catalog → Trips), as Save trip as template does: its design, its blocks, its quotes as draft proposals, its headcount, presentation and start date. The trip must have a design (else 422 `trip_has_no_design`). The trip is read as it is now — its itinerary is not synced first. Needs `trips:read` as well. Undo with POST /changes/{changeId}/revert.

**Permissions:** `catalog:write`, `trips:read` · **Kind:** write · **Cost:** 2 units · MCP tool [`save_trip_template`](https://api.bymundi.com/docs/mcp/tools/save_trip_template.md)
