 * speak: a double line with PCB corner pads, steel type banners, chip squares
 * for numbers, a terminal footer. Page files keep only what is theirs.
 *
 * The palette is the locked E1 "Plate" palette. Affinity owns the accent;
 * ember is the one action colour, so a player learns "ember means act" once
