LGT-013

Hard rule priority 78 domain: lighting vfx

Rationale

Uneven backing increases keying and spill failures.

IF — conditions (all must hold)

lighting.chroma_background_uneven eq true

THEN — actions

add_flag "CHROMA_UNEVEN"
append requirements "even_screen_and_separate_subject"

This is a hard rule: when it matches it participates in blocking — the pipeline may not proceed until the condition is repaired or a human accepts the risk.
