/* The sample catalogue's stylesheet. One file, no framework, no build step -
 * the same rule the three repository pages this replaces followed.
 *
 * The palette is the playground's own (src/shell/shell.css), copied rather
 * than imported: this page is a separate document that must paint before any
 * module has been evaluated, and a second stylesheet request in front of the
 * first paint costs more than fifteen duplicated lines. Change them together.
 *
 * Light is defined on bare :root, dark twice - under the media query for a
 * reader who has expressed no choice, and under [data-theme="dark"] for one
 * who has, so the switch wins in both directions. */
