/**
 * Numbers Practice Widget styles.
 *
 * Brought in line with the fleet (2026-07-24): the merged header + settings
 * gear + directive-blue instruction band + task field are rendered by
 * universal-header (createExerciseLayout); pips use the shared .ex-* classes;
 * colors come from the fleet --as-* design tokens (cyan = audio, green = tap/
 * action, blue = read, amber = hint). Reference widgets: math-practice
 * (standalone/topicless container + settings-behind-gear), listening-practice
 * (cyan audio + green choice grid), naming-practice (clinician ✓/✗ pattern).
 *
 * No !important; interactive selectors prefixed with `.numbers-practice-root`
 * to beat the Elementor kit the clean way (math-practice pattern); >=44px
 * touch targets; mobile-first-ish with 768/380 breakpoints.
