/* The community hub — the docs' tokens, arranged as a shelf rather than a book.
 *
 * Structure borrowed from the sharing platforms that work (MakerWorld, and The
 * Flock's feed): a boot/hero that states the deal, four cards naming the kinds
 * of contribution, a filterable shelf, open challenges, then the manual itself.
 *
 * What is NOT borrowed: fabricated activity. Those sites are full because they
 * are full. This one is not yet, and the empty slot says so — a grid padded
 * with people who do not exist is the one thing that makes a real community
 * impossible to start.
