Every mailer becomes a talking-sign entry — the QR on the front hands the reader to the house itself.
1 · Pick listings
Staff sign-in loads the live list; signed out (or ?mock=1) shows demo data.
No listings loaded yet.
Or paste slugs — one per line, optional label after a comma (demo, 3708 Tarpon Drive). Address and price hydrate from the house itself (anon mcp_curb_home); a dark rail or unknown slug prints a label-only card.
2 · Card face
Faces mirror the poster-engine archetypes (solid navy panels, gold rule, brand line). No photo on file simply prints the flat navy field.
Prints 2 postcards per letter sheet — front page, then the matching back page. Duplex: flip on long edge.
