SpriteNodeMaterial.setupPositionView already rebuilds the billboard quad from
positionGeometry — the prior .add(positionLocal) double-counted it (harmless at
0.1 size). Bare center is required for the upcoming velocity-stretch streak
(scaleNode/rotationNode will drive the quad). Verified renders identically.

The nested 3D-within-3D figure now collides with its shell in OPPOSING color
universes, not a shared rainbow. Each layer is painted from a hard duotone:
the outer shell from one world (ice / acid / gold / mint / electric-blue), the
inner figure from its enemy (fire / blood / violet / crimson / gold). A new
uClash uniform cycles the pair every beat (and randomizes per dream figure), so
it's a fresh ice-vs-fire / acid-vs-blood collision each time — the kind of
contrast that stops a scroll.
To make the clash READ instead of washing white: inner glow floor dropped hard
(dense small-radius overlap was blowing to white and killing the color), inner
figure scaled up to 0.52 (spread → less overlap), the color blast capped at 0.6
mix so the duotone shows through even during a detonation, and Act II/III
ignition lowered 8.0→4.5 so beats no longer flash the clash to white.
Gate: svelte-check 0/0, 937/937 tests pass, build green, verified live (gold
shell + violet core clash reads clearly, no white-out, beats 0/1 calm).

Three upgrades to Memory Cinema:
1. IMPOSSIBLE-GEOMETRY FORM PACK — replaced the stringy ribbon dream worlds with
brand-new signature skins nobody ships as a living particle figure:
- world 8 → Calabi–Yau quintic cross-section (6D string-theory manifold,
Hanson 4D→3D projection; α rotates it through the 4th dimension)
- world 9 → Boy's surface (Bryant–Kusner minimal immersion of RP²)
- world 10 → Aizawa attractor shell (breathing strange-attractor skin)
- world 11 → Gyroid↔Schwarz-D Bonnet morph (triply-periodic minimal surface)
The (u,v) MANIFOLD GRID basis is the key fix: particles map over a tensor grid
so neighbors share edges → reads as a sculpted SKIN, not spaghetti. Plus a
facing-ratio Fresnel rim so forms read as lit solids. Inline complex-math +
hyperbolics (sinh/cosh not in three@0.172). atan2→atan (deprecation).
2. 3D-WITHIN-3D NESTING — ~34% of particles form a SECOND, smaller, counter-
rotating figure (a different world, ~45% scale, complementary hue) at the core
of the outer shell. A figure inside a figure — fills the formerly-blank-bright
center with intentional structure and depth.
3. DEMO-CAPTURE MODE — press H in the cinema overlay to hide all UI chrome
(top bar + captions) for clean recording; a faint restore hint remains.
Overlay z-index raised + body.cinema-open hides the graph page's stats pill so
nothing bleeds through.
Gate: svelte-check 0/0, 937/937 tests pass, build green, verified live (Calabi–Yau
+ nested core render, forms cycle, no errors, beats 0/1 calm).

The 7-beat tour no longer freezes on the last figure. When it ends, Memory
Cinema drops into an infinite generative loop: every ~5.5s it morphs into a
fresh RANDOM procedural figure and detonates a color blast — each crazier than
the last.
Five new procedural worlds (7..11), parameterized by a per-figure uMorphSeed +
a uChaos ramp so the same index never looks the same twice:
7 supershape (3D superformula) 8 torus knot (random p,q winding)
9 warped lissajous lattice 10 helix storm
11 quantum foam (curl-warped chaos — max wild)
storm.dreamBeat() picks a random world, reseeds it, ramps chaos, and fires a
moderate-ignition blast (kept below the tour's 8.0 so dense random figures don't
wash white). Surfaced via sandbox.dreamBeat(); MemoryCinema starts a dream timer
on director onComplete, shows "∞ Dreaming", and tears it down on close/replay.
Honors reduced-motion (no dream loop) and the render-fail fallback.
Gate: svelte-check 0/0, 937/937 tests pass, build green, verified live (reaches
dream mode, generates distinct figures — supershapes, torus knots — cycling
forever, no white-out, no errors).

Memory Cinema is now a choreographed 7-act journey. One 150k-particle pool,
one compute kernel; a uWorld state machine select()s which home-target + forces
are live, and uBlend crossfades world→world over ~1s. The particles never swap
— only the forces on them — which IS the journey.
The seven worlds (beats map 1:1, beatIndex % 7):
0 nebula mist (curl-noise flow) 1 orbital anchor (cross-product spin)
2 strange attractor (Thomas) 3 detonation void (staggered shockwave)
4 crystal lattice (voxel snap) 5 fluid galaxy (curl + tangential swirl)
6 phyllotaxis bloom (Vogel sunflower, golden angle)
The signature COLOR BLAST: a long-lived uBlast envelope (~2.8s, decoupled from
the fast physics burst so the color OUTLIVES the shockwave) drives an outward
SPECTRAL DISPERSION wave — concentric rainbow rings expanding through the radius
over uBlastTime (real prism order, red lags / blue leads), with a warm blackbody
ember core underneath. Spectrum dominates so the detonation reads as RAINBOW,
not a white plasma flash.
Plus per-world cosine palettes (IQ) so each world is a distinct PLACE. All the
white-out guardrails preserved + extended: rim-gated blast, capped kelvin/gain,
emissive blast held below the color path. Beats 0/1 stay calm (low uBlast),
Acts II/III blaze.
Frontier techniques sourced from a parallel web-research + design workflow;
verified against the installed three@0.172 TSL build. Retires the old uShape
5-form gallery.
Gate: svelte-check 0/0, 937/937 tests pass, build green, verified live (7
distinct worlds, spectral blast, no white-out, calm opening).

Memory Cinema storm color/shape overhaul (the crown-jewel pillar):
- Fix the white-out root cause: emissiveNode was NEVER set, so the selective
MRT bloom had no color to bloom and washed the frame white. Route the shared
iridescent rainbow to BOTH colorNode and emissiveNode.
- Rim glow (fresnel-style): bright glowing edges, dim readable center — the
shareable luminous-shell / hollow-torus look.
- Morphing geometry: the home target cycles sphere → torus → galaxy spiral →
cube lattice → wave sheet, drifting continuously and snapping per beat.
- Hyper-saturated full-spectrum palette (per-particle phase + radial shells +
spatial bands + time) so the whole rainbow is present at once.
- Spread the initial spawn across a wide hollow shell (was a tiny dense ball
that boot-flashed white).
- Act/beat-aware brightness: beats 0/1 fade in soft, Act I held calm, Acts
II/III blaze at full. No white-out regressions.
Gate: svelte-check 0/0, 937/937 tests pass (cinema auteur/pathfinder green),
verified live in browser.

Per direction: keep the mind-blowing explosion + pixelation moments, ditch the
thin ribbon swirls. Complete physics rewrite:
- removed orbital/stream/Rössler modes (the swirls + the off-center drift source)
- each particle has a deterministic HOME on a volumetric shell around ORIGIN
(centroid anchored — can never drift off-frame again)
- uBurst detonation cycle: every beat blows particles radially out (explosion),
then a home-spring crystallizes them back (reform); contradictions detonate hardest
- PIXELATION: positions snap to a 3D grid that's fine when reformed, dissolved
during the burst — the crystalline voxel look
- hard velocity + radius clamps so it can never fly off or blow up

Storm was a small ring leaving the canvas empty, and the core blew to white.
- FILL: sandbox fitRadius margin 0.40 -> 0.82 so the storm fills most of the
frame; particles now target their OWN radius across 0.12r..0.92r (filled
volumetric ORB, not a thin ring).
- COLOR: brightness was x(ignition*2.4+0.6) = up to x19.8, which + additive
blending across 150k sprites clipped every channel to white. Clamp the glow
low (0.45 floor, ~1.15 ceil) so the RAINBOW shows as pure spectral color;
smaller quads (0.18 -> 0.1) keep particles crisp instead of overlapping to
mush; gentler bloom (strength 1.1->0.6, threshold 0->0.35) accents cores
rather than washing the cloud. 937 tests + build green.

The rainbow storm looked next-dimensional but still clipped the edges — the
additive bloom halo extends each particle's glow well past its geometric radius,
so the visible cloud was bigger than the contain sphere.
- spawn radius 15 -> 8 (particles start inside the shell, no asymmetric inward yank)
- sandbox fitRadius margin 0.55 -> 0.40 (leaves room for the bloom halo)
- camera band tightened + pushed farther (30-44) so the contained cloud sits
small + centered; director standoff clamped into that band in centerOnOrigin
mode so the camera never fights the per-frame clamp (the off-center jump).
937 tests + build green.

Fixes the runaway ring (screenshot showed an expanding ellipse clipping the
frame): orbital mode added tangential velocity with nothing pulling particles to
a target radius, so they spiraled outward. Now a two-sided RADIAL SPRING pulls
every particle toward an in-frame shell (containRadius*0.62) with a per-particle
band so the cloud is a contained breathing sphere, not an ever-growing ring.
Tighter velocity clamp + boundary snap as belt-and-suspenders.
Color: replaced the flat 3-color tint with a living iridescent RAINBOW — hue
drifts by per-particle phase + radius + time + a global rotating hue shift
(fract/abs hexagon palette). Dramatic beats blend their mode color over the
rainbow (crimson at contradictions, gold at surprises) via uModeTintAmt; calm
beats stay mostly rainbow. 937 tests + build green.

Root cause: layoutPositions grew per beat (radius 22 + i*6), so each beat sat
farther out; the camera + storm marched off into space as the tour progressed.
Fix (centered-by-construction):
- layoutPositions: tight BOUNDED golden-angle shell (SHELL_RADIUS 14), no growth.
- sandbox: storm pinned to the WORLD ORIGIN permanently; camera hard-clamped to
an 18-46 unit distance band and always lookAt(origin); containment sphere
sized to the FOV at origin. A runaway move is corrected every frame.
- director: new centerOnOrigin mode (enabled when WebGPU active) — frames/orbits
the origin instead of flying to scattered nodes; variety from angle/standoff.
No path remains for the subject to leave frame. 937 tests + build green.

director.ts: optional shots:ResolvedShot[] in DirectorOptions; per-beat
flight/dwell timing; framePosition now reads move (push_in/pull_back/crane
scale standoff) + angle (low=look-up, high=look-down) + standoff; orbit shots
revolve the camera during dwell; Dutch roll via camera.up; hard/match cuts
snap (editorial cut). With NO shots the camera is byte-identical to before
(all values fall back to the existing constants + easeInOutCubic lerp).
MemoryCinema.svelte: build computeSignals + planShotsDeterministic + resolveShots
on launch, pass shots to the director; onBeat drives storm mode + director's
note + Act + tension from the shot. New UI: pre-roll DIRECTOR'S PLAN card
(logline naming real memories), per-beat 'why this shot' note, Act I/II/III
badge, tension-tinted progress bar, Auteur source badge.
The deterministic auteur ships the hero film with zero LLM. 937 tests + build green.

Particles (esp. the unbounded Rössler chaos mode) could fly off-screen. Add a
camera-frame-sized spherical containment field: spring pull-back past the
radius, hard velocity clamp, and a snap-to-shell safety net so no particle can
escape. The sandbox sizes the radius from camera distance + vfov each frame so
the storm reframes as the camera flies. Verified: check + build green.
storm.ts (blockers): correct particle position wiring — positionNode now
instancePos.add(positionLocal) (bare storage element collapsed every quad to a
point); serialize GPU compute dispatches (computeInFlight) to stop queue
stalls; ignition floor so the storm never fades to black; null buffers on
dispose for GC (StorageBufferAttribute has no dispose()); typed computeNode +
InstancedMesh, removed unsafe casts.
narrator.ts: validate + filter backend beats, bounds-safe fallback merge,
KIND_CHIP satisfies (compile-time enum coverage), chip type guard, timer cleanup.
MemoryCinema.svelte: replace the null-returning Local AI stub with a real
on-device transformers.js text-generation pipeline (+ genuine fallback);
Escape-to-close + autofocus a11y; reset all run state on launch (no stale
Replay); fix render/close race; computed fallback camera aspect; typed state.
director.ts: NaN-guard progress on empty path; clamp dt >= 0.
sandbox.ts: guard three/webgpu exports + tsl pass() API shape; resize w/h floor.
926 tests + build green. Net: every audit blocker/high/medium fixed.
