// The 40 m grid → sector map the client's Gadget streaming needs, taken from
// AnantaGadgetLoader's own runtime export (src/cells.json, "runtime export from 4229938
// client": 5,116 cells, variable-length sector lists — 4,858 outdoor cells carry the single
// sector 0, ~333 cells carry hashed interior sector ids and some carry 2-5 sectors).
// Why it matters: SyncGadgetGridAOIDecrease takes ONE sector list per message, so cells
// with different sectors cannot ride in the same push. The loader's author proved this —
// sectorIdList=[0] loads outdoor props only, indoor furniture needs the interior ids.
// A missing cell is not an error: the caller falls back to sector 0 (outdoor), which keeps the
// channel alive instead of silently dropping that part of the map.
