Session handoff: live-cdb grounding shipped Fix A (point-light shape), Fix B
(per-object selection), Fix C (sun-vector magnitude / ~32% over-bright). Fix D
(outdoor objects too bright near torches) is fully grounded but BLOCKED on one
capture (the building's render path) — the D3D-FF math says it'd make objects
brighter, so not ported. Full cdb cheat-sheet + the contradiction + the next
capture in the doc.
