radianceCache

A world-space store of lighting results that survives the frame that produced it. create(name, opts) hands back a cache that owns its own fixed table of slots, addressed by hashing a world-space cell, so it covers an unbounded world in bounded memory.

A technique either drives the built-in screen-space producer with run, or enqueues its own producing pass over bindings() and lets the cache own the table, the addressing and the eviction.
