Weaving API

Weaving and loom maths as an API, computed locally and deterministically — the warp, weft and sett numbers a handweaver warps a loom by. The warp endpoint computes the total ends and the warp yarn for a project: ends = warp width × EPI (ends per inch, the sett), and the warp length per end = the cloth length adjusted for take-up (~10 %) and shrinkage plus the loom waste (~24 inches of thrums), so a 20-inch-wide piece at 12 EPI woven to 60 inches needs 240 ends and 600 yards of warp. The weft endpoint computes the weft yarn from the picks per inch, the width and the woven length: picks = PPI × woven length, each crossing the width plus the draw-in. The sett endpoint turns a yarn's wraps-per-inch into the ends-per-inch to set: a balanced plain weave is half the WPI, twill two-thirds, satin three-quarters — so a yarn that wraps 24 times per inch setts at 12 EPI for plain weave. Everything is computed locally and deterministically, so it is instant and private. Ideal for weaving, fiber-arts, textile and craft app developers, warp-calculator and project-planning tools, and weaving education. Pure local computation — no key, no third-party service, instant. Imperial inches in; yards out. Live, nothing stored. 3 compute endpoints. Take-up, draw-in and loom waste have sensible defaults — measure your own loom.
