Weekly class schedule

Built for a gym, a dance or a music school: each class shows time, level, teacher, room and remaining places, with a fill gauge and a Last place or Full label. Two filter groups (discipline, level) and a Hide full classes checkbox combine; a status region announces how many classes are shown and each empty day says so. On desktop the week shows as six columns; below 768 px it becomes day-by-day tabs that show how many classes remain after filtering, opened on the current day. Discipline colors are CSS variables that are easy to change. Accessibility: filters are toggle buttons (aria-pressed), ARIA tabs with arrow, Home and End keys, place information never relies on color alone, AA contrast in light and dark modes, transitions disabled with prefers-reduced-motion. Without JavaScript the whole week stays readable.
