/*
 * Bent Mace Apps — the gallery's own stylesheet.
 *
 * This file is served publicly. Keep it self-contained: no internal project
 * names, no repository paths, nothing that only makes sense from inside. The
 * build asserts on that, but it is easier to just not write it.
 *
 * The sub-apps have their own styles and never load this; it dresses one page.
 *
 * The premise, which the rest of Bent Mace shares: the page has no colour of
 * its own — every saturated pixel on screen belongs to an artist. That lands
 * harder here than anywhere else, because the artwork is nineteen thumbnails,
 * all of them somebody's shader or synth, sitting on paper. So the page is ink,
 * rule and weight, and the work is the only colour. Do not add an accent.
 *
 * Dark mode is a media query with no toggle, matching the website — a toggle
 * needs persisted state and a control to hang it on, and this page has neither.

   * only at those sizes. #5f5e5a is 4.82:1 and is otherwise the same colour.
