/*
 * Course-only rules for the nursing OSCE pages. Linked AFTER the site's theme.css (or, standalone, after standalone.css).
 * Colours come from theme tokens only (--accent and friends, --ink, --wash, --night ...). No colour value is written out
 * here; a test fails the build if one appears. Sizes use rem so browser zoom and user text settings work.
 * New classes start with "oc-" so they never collide with theme.css (which already owns .stage, .why, .steps ...).
 *
 * Motion: one authored moment, in the hero sample (the station line draws, two points tick, the missed safety point is
 * flagged and its reason appears). Everything else is feedback: ticks fill, bars grow once. All of it stops under
 * prefers-reduced-motion, and the resting state is always the finished state.
