/**
 * weekly-schedule.css — the "Full Weekly Schedule" card.
 *
 * @version 1.0.0
 *
 * The markup is generated by scripts/gen-schedule-html.mjs into index.html,
 * campbell-river.html, cortes-island.html and tomorrow.html. Change it in the
 * generator, never in the pages. The card is a native <details>, so it opens
 * with no script and does not go through toggleCollapse().
 *
 * Filtering is pure CSS: the direction and day controls are radio buttons, and
 * :has() hides every section and day group that does not match the checked
 * ones. The HTML always carries the whole week, which is the point of the card
 * (crawlers read it). Where :has() is unsupported the controls stay hidden and
 * the whole week shows. The inline script under the card only preselects today.
 *
 * tomorrow.html loads none of the shared CSS and defines only a few tokens, so
 * every var() below carries a literal fallback. Dark mode arrives two ways on
 * this site ([data-theme="dark"] and body.dark-mode), so every hard-coded
 * colour is a --ws-* token redefined under both.
 *
 * Linked non-blocking (the media="print" swap): the card starts collapsed and
 * sits at the foot of the page.
