SDF zero cost demos
Below: free color 20s + Chebyshev SDV field. 2d free always. GPU optional. Desk free limbs unchanged.
RTX panel · SDF zero cost · free demos
SDF free · free color · SDV scrap · detect ladder
Safe ladder: 2d free always (zero cost) → WebGL optional → WebGPU optional → RTX string bonus. Have-nots still IN.

SDF zero cost
Free color · zero cost field
free color spirit · 20s loop on desk · zero cost limb
SDF / SDV · Chebyshev L∞ shells
L∞ free field scrap · desk x/sdf · x/sdv · x/free · eikonal 7
Detect ladder · haves & have-nots
- 2d free — primary · zero cost
- WebGL — optional only
- WebGPU — optional · fail-soft
- RTX string — bonus · not required
Have-nots never break the demo. Free eor digits still run on the desk.
Limbs · free / tax / RTX
RTX string = bonus path · free 2d still primary
SDF FREE eor · abs · cheby · zero cost hot path
TAX when busy · remain IN
