remove.mjs

#!/usr/bin/env node
// Append a validated takedown entry to removed.tsv (the archive's removal source of truth) —
// safer than hand-editing the TSV. generate.mjs then drops the item from every surface.
//
//   node remove.mjs sprite <id> "<reason>" [YYYY-MM-DD]
//   node remove.mjs tune   <id> "<reason>" [YYYY-MM-DD]
//   node remove.mjs user   <id> "<reason>" [YYYY-MM-DD]    # profile + de-attribute + scrub handle
//   node remove.mjs comment <spriteId>                     # LIST a sprite's comments + their keys
//   node remove.mjs comment <spriteId>#<hash> "<reason>"   # remove ONE comment
//
// After adding, regenerate + deploy (see README "Removing content"):
//   node generate.mjs
//   aws s3 sync public/ s3://pixieengine-static --delete
//   aws cloudfront create-invalidation --distribution-id E2QQUW2BPHXXNP --paths '/sprites/<id>/*' ...
//
// For an URGENT/ILLEGAL sprite takedown, ALSO delete the image object(s) on the CDN bucket —
// the static rebuild does not touch them. See README "Removing content".
