Summary

  • Replace Colorlip with the existing Sharp/libimagequant palette quantizer; remove the dependency.
  • Keep a straightforward image → swatches → palette → accessible text pipeline, without custom sampling or coverage rules.
  • Prefer prominent colorful swatches for backgrounds, retain image-derived accent/muted colors, and choose black/white text by contrast against the softened solid background.
  • Keep Preview/Publish workflow and embedded palette contracts unchanged; trim tests and document regeneration.

Validation

  • Code and test reviews complete.
  • 337 worker tests and coverage thresholds pass.
  • Clean production build, lint, formatting, diff check, manifest/lockfile consistency, and compiled palette smoke calculation pass.
  • Full test-inclusive type checking has 14 pre-existing diagnostics, identical to an isolated main/HEAD baseline; no new diagnostics.
  • Supplied cover produces blue #66849c with black text at 5.35:1 solid-background contrast.

Scope

Existing OG templates with translucent image overlays can still alter final rendered contrast; that visual template change is documented and deferred. No live Preview/Publish jobs, browser tests, or image inspection were run for this iteration.
