// Canonical Protestant Bible book list, in canonical (Genesis → Revelation) order.
//
// This is the single source of truth for book names/aliases, shared between the
// client (src/App.tsx, for the Scripture Index page) and the server
// (server/routes/bible-passage.js, for the BSB/bolls.life passage-fetch API).
// Previously these lived as three independent, hand-maintained lists with
// different key formats (spaced names + 3-letter ids in the client, unspaced
// names + numeric ids on the server) that could silently drift out of sync.
//
// - `id` is the 3-letter USFM-style book id used by the bible.helloao.org API.
// - bolls.life's book numbering is exactly this array's 1-based canonical order,
//   so no separate numeric-id table is needed — see bookNumberFor() below.
// - `aliases` are additional short forms admins/users might type (abbreviations).
