- * fetch-materials.mjs — Copies mirrored materials from DOSSIER-LIBRARY into
- * public/assets/materials/ and regenerates src/materials/library.ts and
- * public/assets/materials/manifest.json.
- *
- * The 12 hand-authored starter entries in library.ts / manifest.json are
- * preserved (they appear first). Broad-set entries are appended/merged
- * (existing broad entries are replaced if the source has changed).
- *
- * Usage:
- *   node scripts/fetch-materials.mjs --library /home/karim/DOSSIER-LIBRARY
- *   node scripts/fetch-materials.mjs --library ../DOSSIER-LIBRARY --dry-run
- *
- * The --library flag (or DOSSIER_LIBRARY env var) points to the local mirror
- * root. When a git remote is set up, pass a local clone path here.
