SHAPE

Procedural 2D shapes: a primitive drawn as a signed-distance field, with symmetry, an independent fill and outline, and per-primitive contextual parameters.

Parameter	Control	Notes
Primitive	Selector	Circle, Square, Triangle, Star, Polygon, Superellipse, Lissajous, Spirograph.
Blend	Selector	Add, Multiply, Screen, Difference, XOR, Phoenix, or Replace into the chain.
Symmetry	Selector	None, Bilateral, RotationalN, Kaleidoscope.
Sym N / Poly N / Depth	Trough	Symmetry repeat count, polygon side count, and IFS recursion depth.
Size / Position	Knob, Pad	Overall scale and X/Y offset.
Scale Factor / Rotation Per Level	Trough	Per-level falloff and rotation, when Depth > 1.
Color	Trough	Fill color, R/G/B.
Edge Smooth / Superellipse Exponent	Trough	SDF edge softness; exponent only affects the Superellipse primitive.
Contextual	Trough	Up to four rows that rename themselves per Primitive: Lissajous shows Freq X, Freq Y, Phase, Damping; Spirograph shows R, r, d.
Outline	Selector, Trough	Off, Outline Only, or Fill+Outline, with its own color, opacity, and width independent of the fill.
