/*
 * The admin panel's own stylesheet.
 *
 * Separate from the shop's style.css rather than shared. The shop is a dense
 * data table tuned for scanning prices on a phone; this is a control surface
 * with forms and status cards. Sharing one file would have meant every shop
 * tweak risking a control here, and the shared part (the colour tokens) is
 * twenty lines that are cheaper duplicated than coupled.
 *
 * `[hidden]` is restated at author level on purpose. The user-agent rule
 * `[hidden] { display: none }` loses to ANY author rule that sets a display,
 * regardless of specificity, which is how the shop once shipped a permanently
 * visible empty error banner pinned over the viewport.
 */

/*
 * Theming, in three layers, and the order is the whole mechanism.
 *
 *  1. `:root` carries the COMPLETE light palette. Every colour used anywhere
 *     is defined here, so no token can exist only inside a media query.
 *  2. The dark values are redefined under `prefers-color-scheme: dark`, guarded
 *     so an explicit light choice still wins over the device.
 *  3. The dark values are redefined again under `[data-theme="dark"]`, so the
 *     toggle wins in both directions.
 *
 * `data-theme-default` is stamped by the server from `ui.theme` and read by
 * the inline script in index.html, which resolves it against localStorage and
 * writes `data-theme` before first paint. That is why there is no flash: the
 * decision is made before the document has any pixels.
