 * lsm.css - the stylesheet of the LazySubmodules documentation site.
 *
 * It sits on top of the Furo theme and sphinx-design. Everything it adds is
 * either a token (--lsm-*), a class the pages use (.lsm-*), or a small
 * refinement of a Furo component. Colors come from docs/assets/social-preview.svg
 * and from the state colors the program prints; every text pair reaches a
 * contrast ratio of at least 4.5:1 in both themes.
 *
 * Dark values are declared twice, as Furo does it: once for the system
 * preference (unless the reader forced the light theme) and once for the theme
 * the reader picked.
