Introduces scripts/pipeline/, a Mix project that runs as a post-export
transformation pass over content/*.md before Quartz builds the site.
Pipeline (scripts/export.exs phase 3):
- Compiles and loads the Mix project at export time (cached after first run)
- Applies a list of Transform modules sequentially over all .md files
- Only rewrites files that were actually changed
Citations transform (Pipeline.Transforms.Citations):
- Resolves [cite:@key] and bare cite:key syntax produced by ox-hugo/citar
- Resolution chain: Zotero BBT JSON-RPC → BibTeX file → DOI/bare-key fallback
- Zotero probe uses a no-op JSON-RPC call (cayw endpoint blocks indefinitely)
- Zotero resolver fetches PDF attachments via item.attachments, producing
zotero://open-pdf/... links; falls back to zotero://select/library/items/...
- BibTeX resolver parses .bib files with a simple regex parser (no deps)
- DOI resolver is the always-succeeding last resort
Configuration via env vars:
BIBTEX_FILE — path to .bib file for fallback resolution
ZOTERO_URL — Zotero base URL (default: http://localhost:23119)
CITATION_MODE — silent | warn (default) | strict
Adding future transforms requires only implementing Pipeline.Transform
behaviour and appending the module to the transforms list in export.exs.
