/**
 * check-packet-a1-structure — the prayer packet is built to its specified structure.
 *
 * FULL DETAIL is four front pages, the profiles, four back pages:
 *     map · triangle · life calendar · % evangelical · profiles… · bounded set · centered set · wheel · points
 * LIGHTWEIGHT is two front pages, the profiles, two back pages:
 *     map · triangle · profiles… · wheel · points
 * and the pages that carry the design are the ones described: page 1 is the zone's map on a VERTICAL
 * page with a title saying which set it belongs to; page 2 is one inverted triangle narrowing from
 * every people group to THIS packet; the wheel is the Metacamp Module 1 wheel, in its colours and its
 * orientation.
 *
 * ★ ORDER IS READ FROM EACH SHEET'S CONTENT, NOT COUNTED. A sheet total can hold while two pages swap,
 * or while one page is lost and another duplicated. Every sheet is identified by what is on it.
 *
 * ★ TWO-SIDED WHERE A ONE-SIDED CHECK WOULD PASS A CONSTANT: the packets tier must appear WITH a packet
 * count and must NOT appear without one; the series line likewise; a "− N" step must appear where the
 * sets nest and must NOT appear where they do not.
 *
 * Exit 0 pass · 1 fail · 75 NOT MEASURED.
