houseplan-card/demo/smoke_floor_geometry_cache.mjs

// #744: the four floor-geometry caches (physical bodies, the wall union,
// inner room contours, the clean floor) are keyed by the content of ONE
// floor's record, not by the global config epoch.
//
// AC1  an edit of `f1` (a rename through the room dialog) leaves `garden`
//      warm: its first visit after the edit builds nothing. On the epoch key
//      the visit rebuilt the union (+1), every contour and clean floor (+N).
// AC2a a server push that changes walls of BOTH floors (shared walls: one
//      thickness moves the faces of two rooms) while `f1` is on screen: each
//      floor draws the walls and areas an independent card computes from
//      scratch on the same config, and they differ from the previous ones.
// AC2b a stair placed on `f1` through the stairs tool shrinks the room by its
//      footprint, as the independent card says, and `garden` keeps its clean
//      floors (the stairs editor used to clear the cache of every floor).
// AC2c a live Resize preview on `f1`: the frame follows the preview record,
//      as the independent card on that record says; cancelling restores the
//      walls and areas of the stored record.
//
// The independent card is the oracle: a new `houseplan-card` given the same
// config through its own `config/get`, with nothing in its caches to reuse.
// Card internals are read-only here; writes go through the harness facade,
// the room dialog, the stairs tool and real pointer input.
