## Summary
Closes#17.
- Join USPS EDDM GIS stats onto the carrier-route picker (household size, median income, business count) and link to the official EDDM map.
- GIS miss stays a dash and does not block Find routes; PCM households/cost unchanged.
## 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
Empty PCM_RETURN_ADDRESS was sending SITE_NAME as firstName with blank street fields, which PCM rejects with 400; validate early and wire PCM env through compose.
Classify payloads on /webhooks/smtp2go/ so one SMTP2GO webhook covers both channels under the 10-webhook limit; keep /email/ and /sms/ as aliases and harden SMS event matching.
Add merge tags for email/SMS, paginated removable recipients, PCM event panels for postcard campaigns, and a portal modal when phone/address matches an existing contact.
Add a Quill email editor with DB-backed image storage, selectable PCM designs, postcard defaults for addressed contacts, and merge-by-phone/address on the contact form.
PCM DirectMail v3 needs POST /auth/login (apiKey+apiSecret) before design/order calls; accept each subscription's copy-only signature secret via PCM_WEBHOOK_SECRETS.
Unignore site/ (was blocked by mkdocs /site rule), add compose/Docker/uv tooling, and split deploys so push to main goes to beta while prod stays manual.
