1// nx_epub_fixture_build.nx -- build a deterministic, real-format EPUB fixture via the sovereign OPC zip writer
2// (opc_write, STORED + real CRC-32s). The personal NAS library isn't always mounted and a public fetch can fail;
3// this gives the reader rungs (R-TOC nav-doc parse + R-ART artwork extract) a controlled REAL EPUB to verify
4// against end-to-end (rule 7), with KNOWN expected values for the liar-kill gates.
5// Structure exercises every path: manifest item properties="nav" (EPUB3 nav location) + an NCX (EPUB2 fallback) +
6// a nested TOC (Part Two > 2.1 / Chapter Three) + a cover declared BOTH ways (<meta name=cover> AND
7// properties="cover-image") + an inline <img> in ch2 (embedded illustration). Image bytes are distinctive
8// placeholders (extraction/CID is byte-exact regardless; real PNGs come from real books).
9// expect_exit: 0  license_tier: ORIGINAL  (prose = public-domain Alice in Wonderland)

She tried to look down and make out what she was coming to, but it was too dark to see anything.</p>\n<p>Down, down, down. Would the fall never come to an end?
