 *
 * Direction A (2026-07-29): the page as the title spread of a commemorative
 * anthology — bright cream paper, vertical-set Mincho display title, a
 * table-of-contents lineup, one vermilion seal accent. Replaces the previous
 * dark concert-stage treatment wholesale; no vinyl, no beams, no neon.
