Build the library: polish and extend from a 2-table draft into the full guided build — all four tables, the authors→books 1:n and the books↔members m:n through the loans bridge (bridge-table concept taught in context), the isbn unique constraint, and captured show-relationships / show-data output. Remove the draft marker; it is now publication-quality. Uses the same sample rows as the Reference pages so output matches across the site. Querying with joins (new): joins built up from two tables → the three-table bridge join → a filtered join → a group-by aggregate, all in advanced mode with real captured output. Verified: pnpm build clean (25 pages); no forbidden terms; internal links resolve. Advanced-mode `mode advanced`/`mode simple` and the unique constraint checked against source.
