First batch of code lifts: hardware-agnostic curve math packages.
- bezier/: cubic + quadratic Bezier curve representation +
tessellation. Lifted verbatim from Gangleri42/seedhammer
@ 0a3c63ef path bezier/. Stdlib only.
- bspline/: B-spline curves + an LP-based optimiser that finds the
smallest engrave-stroke representation of a path. Lifted from
Gangleri42/seedhammer @ 0a3c63ef path bspline/. Depends on
bezier/ + gonum (BSD-3, brought in transitively).
Import paths rewritten from `seedhammer.com/X` to
`github.com/mineracks/seedhammer-v1-companion/X`. No other changes.
go build ./... and go test ./bezier/... ./bspline/... both clean.
Doc.go stubs updated to reflect LIFTED status with the source
commit pinned.
Deferred to next commit:
- backup/ (needs bc/fountain + bc/ur transitively for UR codes)
- font/{comfortaa,poppins,constant}/ (needs font/bitmap runtime)
