I Can See The Pixels: Designing Cross-Stitch Patterns in OCaml
summary
Builds a pixel-first pattern pipeline: a JSON canvas, a terminal editor using notty, a PDF exporter via OCaml PDF generator (which turns out accidentally quadratic), bitmap-font readers (Angstrom parsers) and automated border layout that repeats and transforms motif pieces. Implements OAuth2 upload via a Mirage OS unikernel and a LittleFS-derived filesystem plus a Caqti-backed database and VIF web UI. Deployments stop short but one PDF sells on Etsy for $0.25 (net $0.18).
