Five fiuto-toned gen techniques: flow, growth, packing, lissajous, plasma

[darioabc]

What

Five non-harmonograph generative techniques, each with high-variance variants, all using
the established "light in the dark" finishing pass and fiuto tones so the whole
family is visually consistent. Follows the same approach as the harmonograph pieces.

A new shared gen/Ink.kt centralises the tones, the
SCREEN-bloom + noise-grain finishing pass, and a plasma colour ramp.

Tones lifted from the fiuto repo: navy ground #071426, teal #00D3BB, purple #5E49D6, white.

Piece	Technique	Variants
FlowInk	simplex-noise flow-field streamlines	laminar / turbulent / vortex
GrowInk	differential growth (bounded by maxRadius)	coral / lobes / dense
PackInk	largest-fit circle packing, nested rings	big / dense / nested
LissaInk	nested concentric Lissajous	10 ratios (1:2 … 7:9 + 2 damped)
PlasmaInk	per-pixel sum-of-sines + fiuto ramp	10 random-frequency fields

Notes

• Colour separation: spread-out techniques (flow, growth, packing, plasma) show teal
  and purple as distinct colours naturally; Lissajous is drawn as nested concentric
  figures (teal core → purple rim) so the two accents separate radially.
• Growth reproducibility: Growth uses the engine's global RNG internally, so its
  output is not byte-for-byte reproducible by GART_SEED (the other four are).
• Canvas: 16:9 — GART_SIZE sets the height, width derived. The committed PNGs are
  960×540 drafts (seed 173); re-run without GART_SIZE for 1920×1080.
