Fifty-six minutes is seven eights, a long circuit with stations that can include a short explanation. Eight minutes is enough to try and fail once, which is the right size for a practice station.
Walk the room on a loop. Standing still makes the last stations feel unsupervised. Press space to start or pause, R to reset, and F for fullscreen. The screen can stay awake after you start, using the wake lock your browser allows. Pick the alarm before you begin. A bell, a chime, a beep, or a short digital pulse all come from the Web Audio API, so there is no sound file to wait on.
This page is the 56 minutes countdown and nothing else is running underneath it. Related lengths are linked under the guide if you want a neighbor, and the timer itself stays above the fold.

No. The end is a timestamp. The display is the gap between that timestamp and now, so a background tab does not lose seconds the way a ticking counter would.
