Jeff Emmett	f3684c1467	fix: downscale images to 1024px max before dithering ... Full-res images (1743x1786) took 45s for error diffusion, hitting Cloudflare's timeout. Downscaling to 1024px max keeps it under 10s. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-16 17:01:42 -07:00
Jeff Emmett	94fd3ad4d3	feat: add dithering API with 12 algorithms and screen-print color separations ... Adds on-demand dithering endpoint (Floyd-Steinberg, Atkinson, Bayer, etc.) and screen-print color separation workflow with per-channel PNG exports. Uses hitherdither library with in-memory LRU cache (max 200 entries). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-16 17:01:42 -07:00
