/* shogun.info
 *
 * Several short pages, no scripts. Newsreader for display, the system stack
 * for body, and the system's own Japanese fonts wherever a page quotes
 * Japanese.
 *
 * The palette is bright on purpose: a warm white ground, and one strong
 * colour for each period, used for that page's band, its cards and its
 * diagrams. The theme classes set --theme (the band and accents) and
 * --theme-text (the same hue, readable as text on the ground). White text on
 * every --theme passes 4.5:1. The diagrams in public/images/ copy these
 * colours, so a change here is also a change in bin/make-diagrams.mjs.
 *
 * Light only, whatever the operating system prefers: Julian wants the bright
 * version shown to everyone (16 September 2026). color-scheme and the
 * color-scheme meta tag in the layout keep browsers from darkening it.
