stackwith.me — fallback reference excerpts
Source snapshot: 2026-10-28

These are excerpts from the local source used to prepare this edition.
They describe code, not a successful browser test or the state of a live service.
Line numbers refer to the original file. Full-file SHA-256 identifies that version.
