"""
Public cemetery map schemas (INDL-56).

These are strict, allowlist-only response models for the unauthenticated
`/api/public/map` surface. Every model uses ``extra="forbid"`` so a field that
is not explicitly declared here can never be serialized to a public visitor —
the last line of defence against leaking staff-only data (notes, reserved_by,
record_id, full DOB/DOD, etc.). The service constructs these models explicitly
(an allowlist by construction); ``extra="forbid"`` makes any accidental extra
key fail closed rather than leak.
