   Modals that contain a form
   --------------------------------------------------------------------------
   .modal__panel is a flex column: the head and foot keep their size and the
   body scrolls between them. Three modals (add customer, new customer, correct
   attendance) wrap the body AND the foot in a <form>, which put an ordinary
   block box in the middle of that chain. The body's `flex: 1; overflow-y: auto`
   then applied to nothing, the form grew to its full content height, and
   .modal__panel's `overflow: hidden` simply cut the bottom off — taking the
   submit button with it. That is the "the button to finish adding is not
   appearing and there is no scroll" report: the form was not too long, it was
   unscrollable and its footer was clipped.

   Making the form carry the column through fixes every such modal at once.
   `min-height: 0` is the part that matters: without it a flex item refuses to
   shrink below its content, and the body still will not scroll.

   checked against its own surface for colour-blind separation and contrast.
   Every chart carries direct labels as well as colour, so identity never rests
