interactive.js becomes a multi-mode engine sharing camera, motion grid,
gradient/centroid tracking and the mouse fallback. New renderers: point/line
sprites (mirror/swarm/cloth/pops) and a ping-pong trail FBO (painting).
fluid.js gains a 'touch' emitter mode fed by motion splats from the camera.
Mirror mode reforms the custom SVG/image if loaded, else a DJ LUZA wordmark.
UNPACK_ALIGNMENT set to 1 for non-multiple-of-4 single-channel uploads.

Pi V3D ran the sim at 26fps at full res; with the 3-notch auto-downscale
(dye 1024/768/512) it settles at ~52fps. Never steps back up to avoid
oscillation.

Same solver, different figures via e.fluidMode: 'fire' bottom jets with
buoyancy — implemented as relaxation toward a target updraft (an additive
force integrates to the velocity clamp and turns flames into a wall) plus
height-scaled dye dissipation so flames die as they rise; 'ring' emitters
on a spinning circle with radial beat shockwaves; 'vortex' two counter-
rotating stirrers; 'wave' a travelling sine curtain. Stationary emitters
inject a fraction of the stir force (repeated adds at one spot saturate).
408 new presets.

Stable-fluids solver (fluid.js) on ping-pong half-float framebuffers:
semi-Lagrangian advection, vorticity confinement (clamped — unbounded
confinement overflows half-float and kills the field), 22 Jacobi pressure
iterations, audio-driven dye/force splats. Three wandering emitters inject
palette-coloured dye (brightness-normalized so dark palette entries stay
vivid); bass drives injection and stirring, beats fire directional bursts,
treble adds swirl. Universal modifiers map onto the sim: warp = vorticity,
speed = sim speed (brightness is speed-normalized), sym = kaleidoscope with
a wedge that rotates via rotSpeed, contrast/invert on display.
The Visualizer delegates to FluidSim when the preset has isFluid (flag is
always present so Object.assign merges can't leave it stale). 102 new
presets (17 palettes x 6 variants).
