Temporary payload relays for keyed retrieval.
Dead Drop is the frontend shell for drop.m7. It keeps owner-scoped operator
routes, public keyed consumption, and privileged cleanup in one shared shell without turning
the frontend into a second backend.
What this surface does
Use this site to inspect owner-scoped drops, test the reserve/store/activate flow, resolve
pasted links into drop coordinates, and run admin-only cleanup against the sibling
api.drop.m7 service.
