Mint Vault Throat

Concept
Camera inside a long mint-seafoam glossy plastic ribbed vault corridor looking straight to a distant circular sky exit. Charcoal matte niches hold bone-white marble spheres; brass cylinder knobs line the ribs. A coral-orange translucent glass floor tile strip races to the vanishing point. Exit sky is soft peach to slate-blue. Hard speculars on plastic and metal.
Why this way
Tunnel / corridor vanishing point was unused in the recent stretch (yesterday canyon floor looking up; prior days procession, mirrored pool, bird's-eye map, orbital ring, cliff-into-fog, gateway). Palette breaks peach-coral chasm set and the older violet/copper/cyan/chrome-tetra rut.
Judgment
Attempt 1 locked the readable one-point vault, mint plastic ribs, coral glass floor, brass knobs, bone spheres, sky aperture, and synthetic CGI materials. Not photoreal, not a lone-prop shelf. Kept; no redo.
