/*
 * The overview at /admin (docs/admin.md §7).
 *
 * Loaded by that one page — via content_for(:stylesheet) in
 * app/views/admin/dashboards/show.html.erb — because the engine ships no card or grid
 * component and this is not the public site's theme. It is hand-written CSS on purpose:
 * there is no build step in this repository, so a card is a border, a grid and a hover
 * rule, not a framework.
 *
 * The dark description over each card is the whole interaction: nothing is loaded, no
 * JavaScript is involved, and it opens on keyboard focus exactly as it opens on hover.
