/*
 * Case library, front end.
 *
 * Uses the theme's tokens rather than its own palette, so a case page is the
 * same site as the page that linked to it. The only rules here are ones the
 * theme does not already provide.
 *
 * Logical properties throughout (margin-inline, padding-inline, border-inline)
 * rather than left/right: Arabic is one of the three languages this library
 * commits to, and a right-to-left case page mirrors correctly only if the
 * stylesheet never hard-codes a side.
