/*
 * The site's standard controls (plan Dokument\05 Development\ui-controls, Magnus 2026-10-28).
 * Loaded by mwlPageLayout after css_main and css_button, before the page's own CSS.
 *
 * Checkbox "B" (and the radio button further down): a 16px square with a 1px corner and a grey border. When checked the border turns green,
 * the box gets a faint green fill and a green tick shows inside. Same size in all places.
 *
 * The selector is kept at the weight of "input[type=checkbox]" (the :where part counts as nothing), so a page's
 * own rule such as ".x input" still wins. Pages that hide the checkbox (chips, toggles) keep doing so with
 * opacity:0; this file never sets opacity. A checkbox that draws itself (the switch on the Airports page)
 * carries the class mwl-own-box and is left alone.
 *
 * Colours: --border-check, --bg-check, --bg-check-on and --text-check-tick in css_main (light and dark).
