/*
 * collection.css — a chapter wearing the palette it was finished into (collection.mjs).
 *
 * A palette is a place's colours and lettering, mixed from a laminated folio.
 * It arrives as tokens on main.chapter (--pal-ground, --pal-ink, --pal-accent,
 * --pal-glow, --pal-edge, --pal-type-*) and in three layers, one for each way
 * the chapter was finished:
 *
 *   .pal-colour  read to its end           headings, kicker, drop cap, rules
 *   .pal-type    carried through the lanes the title and section headings' lettering
 *   .pal-light   its own wonders kept      a faint wash over the sections
 *
 * Every colour is mixed with the binding's own, never laid over it, so a palette
 * reads as the chapter's mood in every binding; in a dark binding the ink gives
 * way to the palette's glow and accent. The keepsakes panel at the chapter's end
 * always shows the whole palette, earned or not, so you can see what is to come.
