MAX_LIGHTS_PER_TILE

const MAX_LIGHTS_PER_TILE: 16 = 16

Max lights any single tile can hold. Each tile dedicates MAX_LIGHTS_PER_TILE / 4 = 4 RGBA texels to light indices. Caps the per-fragment shader loop iteration count — the inner loop breaks early on the empty-slot sentinel, so tiles with fewer lights pay only for what they hold.

Raising this increases tile-texture footprint and the saturated- tile shader worst case. Lowering it makes reservoir eviction kick in sooner in dense scenes.
