/* landplan.store - the one stylesheet of the apex site (deploy/site, see deploy/README.md).
 *
 * A holding page until the brand is chosen: system fonts only (no web font, so no request leaves this
 * host), no images, no animation, no JavaScript anywhere on the site. Light and dark follow the
 * operating system through prefers-color-scheme; there is no toggle, because a toggle needs a script.
 * Keep this file ASCII, so that the charset it is served with never matters.
