/*
 * The front page at stramus.space, and nothing else — every rule here is under `.lp`.
 *
 * It borrows the app's palette rather than declaring one: the custom properties (--bg, --panel, --border,
 * --text, --muted, --accent) are set in index.html, follow the OS preference, and are overridden by the
 * theme the user chose in the app. So the landing page is dark for somebody who keeps the app dark, and it
 * cannot drift out of step with it — there is only ever one set of colours.
 *
 * Only the web app loads this. The extension shares index.html but has no front page: it is installed by
 * the time it runs.
