Three fixes in one pass to address visitor feedback:
1. Face was rendering upside down — MediaPipe's lm.y is image-down (0=top
of frame, 1=bottom) and the existing updateSplats() already does a
y-negate to convert to Three.js Y-up. Pre-flipping in lmToCenter was a
double flip. Use lm.y directly so the renderer's single flip lands the
head at the top of the screen.
2. Density and fidelity — interpolate 6 splats per FACEMESH_TESSELATION
edge (~1300 edges → ~8000 face splats vs 478 vertex-only). Amplify
lm.z mapping (×8 vs ×4) so eye sockets, nose, and chin show real 3D
depth. Smaller splat scale (0.006 surface, 0.010 vertices) for finer
point appearance.
3. Foundation-inspired aesthetic — the demo now renders the subject
(face mesh OR procedural fallback) inside a Hari Seldon time-vault:
* Holographic surveyor grid in amber, breathing brightness pattern.
* Slow-rotating two-arm galactic spiral receding behind the subject
(~640 stars, warm core to cool edges, Trantor-evocation).
* 800-star deterministic distant starfield on a spherical shell
(fixed LCG seed so visitors don't see noise flicker).
* 60-particle holographic halo orbiting the subject plane.
Shared pushFoundationContext() drives both face-mesh and synthetic
paths. Synthetic procedural figure densified 4x (240 vs 60 points)
and re-oriented (head→top, feet→bottom) so the y-down convention is
internally consistent.
Camera pulled back to (0, 0.2, -3.5) to frame the galactic context.
Poll cadence 4 Hz → 10 Hz so the spiral animates smoothly. Info panel
gets a Seldon quote and "Seldon Vault" branding. CTA copy reframed to
"Project Subject — render your face into the Vault".
ADR-094 already documents the dual-transport intent; the aesthetic
choices here are content, not architecture, so no ADR update needed.
