/* The certified-managers programme: /certification/, /certification/reading/ and /careers/.
 *
 * Same palette (The Ledger) and the same band rhythm as /nonprofit-operations/ and /consultants/:
 * alternating light and dark full-width sections, mono for labels, Archivo for anything that carries
 * an argument. English only, no language switch: this is a public page in the sense CLAUDE.md means,
 * and the specialist links to it from an English message.
 *
 * Four pages share this file. /certification/ is read by a founder deciding whether to trust a person
 * who linked here. /certification/reading/ is read by a candidate waiting for the next group and
 * carries the waiting-list form. /careers/ and the vacancy pages under it (generated by
 * build/build-careers.mjs) are read by a candidate and carry the application form. Nothing here is
 * scripted.
