## Summary Closes #15. Mirrors westfarn/web_django_template#11. - Compose can target the postcard mailing list **or** find and select one or two USPS carrier routes by ZIP (optional radius). - Estimated cost is shown per route and for the selection (PCM design pricing, else `PCM_POSTCARD_PRICE_*` fallback). - Selected routes order through PCM `POST /order/postcard/with-list-count` — occupant addresses are not imported into Contacts. - Not official EDDM postage; PCM FirstClass/Standard purchased occupant lists on carrier routes. ## Test plan - [ ] Campaign compose: mailing-list audience still quotes list size × per-piece cost. - [ ] Switch to USPS carrier routes, search ZIP 60540 (mocked or live PCM), pick 1–2 routes, confirm household count + estimated cost. - [ ] Saving without a selection is rejected; saving with a quote creates one contact-less Message and shows the route panel on the report. - [ ] Send places `/order/postcard/with-list-count` (not per-recipient `/order/postcard`). - [ ] `uv run python manage.py test messaging.tests.CarrierRoutePostcardTests messaging.tests.PostcardDesignPickTests` Reviewed-on: #16
