Torsade shaders v1 — Melted
The melted torsade rebuilt as its own family head: the same molten strands, with the grid layout rebuilt inside the shader.
A GPU re-imagining rather than a port. The CPU plumbing that maintained the grid of spirals is gone entirely — the shader rebuilds the layout from the count, spacing and axis parameters directly, so the arrangement is an equation instead of a structure to keep in sync.
Everything else follows the melted recipe: discs unioned per pixel, painter order preserved by keeping the last one drawn, and the iridescent cosine spectrum cycling along each strand.
