/* Ninjaverse Docs — light documentation theme.
 *
 * Deliberately NOT the wiki's stylesheet. The wiki is a dark in-world browser; this
 * is a manual, and a manual is read on white. Everything here is self-contained, so
 * this module no longer reads anything out of wiki/.
 *
 * The only piece of the game's own look that carries over is the pixel wordmark and
 * the amber accent — enough to be recognisably Ninjaverse without asking anyone to
 * read tables of numbers off a dark background. */
