/*
 * Owl Keeper — the marketing site's one stylesheet.
 *
 * The same tokens as the app (app-web/src/styles.css): monochrome surfaces,
 * colour only for status, Inter and IBM Plex Mono. Light is warm paper, dark is
 * cold night, chosen by the reader's system. No framework and no build: this
 * file is served as it is written, so it is written to be read.
 *
 * Sections: fonts · tokens · base · layout · type · buttons · header · footer ·
 * sections and cards · product figures · forms · prose · tools · utilities.
