The CALLER supplies the quote `id` — it must be unique, so choose a stable, collision-free identifier (a duplicate is rejected with a 409, never silently merged). `validUntil` is an ISO 8601 instant (the server coerces it). 409s when a quote with the same id already exists; 422s when `validUntil` is already in the past. ## OpenAPI ````yaml /openapi.json post /v1/quotes openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
