/*
 * Pool pages — clearings inside the homepage's night forest.
 *
 * The homepage's discipline, not its layout: one type voice (Cormorant display,
 * Alegreya reading text, Alegreya Sans only for small wayfinding labels), one
 * palette (indigo woodland night, parchment ink, one lantern colour per pool),
 * one rhythm (--pool-step). Tokens come from forest-design.css; the woodland
 * and mist are the homepage's own artwork layers.
 *
 * Every pool shares the order threshold → pool prose → ledger → listing. What
 * differs is the composition of the threshold and the shape of its "Start here"
 * doors, keyed off data-pool-id at the bottom of this file.
