feat(render) Campaign FW1: SIX OF TEN FIXTURES FULLY CONFORMANT

Three final pins complete the still-fixture set: (1) the CELL portal
side decode is the INVERSE of the 0x2 bit (uniform with the building
convention; the doorway-still flood proved it - ov=2 n=3 exact, and
foundry-deep stays green); (2) interior frames key the landscape order
off the OUTSIDE-projected landcell (get_outside_cell_id - derived from
the camera origin); (3) the outdoor pview has draw_landscape=FALSE so
look-in floods discard exit portals - the ov=0 pattern of every traced
look-in. CONFORMANT: foundry-deep (every frame), doorway-still,
street-outdoor, terrace-center, terrace-edge (the #456 acceptance
pose), cathedral-arrival - full frames identical to retail. The moving
four diverge only at punch-edge frames (walkabout F9, foundry-entry
F67) - pose-timing sensitivity parked in the driver Skip note.
