// ── Visible-cell scoping (A7.L1, 2026-07-09 — the Town Network starvation fix) ──
// BuildPointLightSnapshot's player-nearest cap sorts by raw Euclidean distance,
// which is not a reliable proxy for "same room" in a dense, maze-like hub: a
// fixture on the other side of a wall can be geometrically closer than the
// player's own room's torches. The Town Network fountain room (463 registered
// fixtures, cap 128) went dark because far-denser, closer-in-a-straight-line
// corridor fixtures won the cap over the room's own lights. Filtering candidacy
// by the frame's actual visible-cell set (the render already computes this)
// fixes it without touching the distance-sort anchor (still the PLAYER, per the
// #176 correction — camera anchoring is what caused the earlier flicker).
