/* ============================================================
|
||||
proof1-render.mjs — PROOF 1: the lit chamber, split into planes.
|
||||
Takes the locked golden merge composition (REFINED_Backlit7,
|
||||
the mirror event, uniform-lace merge) and emits it as SEPARATE
|
||||
transparent planes for a backlit acrylic stack, plus a manifest
|
||||
and a parallax/backlight simulator to art-direct the depth
|
||||
BEFORE committing to print.
|
||||
|
||||
Plane map (deepest → nearest), causal depth cause→world→evidence:
|
||||
1 sun faded disk · pure transmitted colour · zero white
|
||||
2 sea-far sheet[0]
|
||||
3 sea-mid sheet[1]
|
||||
4 sea-near sheet[2]
|
||||
5 event-halo merged bubbles, blurred by the air gap (glow)
|
||||
6 event-core merged bubbles, sharp · white underlay
|
||||
+ front-glass grain + aging (the surface, multiply)
|
||||
|
||||
Golden frame (φ) is preserved and FLOATED in an A3 sheet later;
|
||||
this stage renders the art square only.

||||
