/* Visor — styles. Colors come from the logo: blue #4DBEDC → green #7BC288.

   The look is Visor's own: a light sidebar on a cool canvas and each page on
   one white sheet, with thin lines rather than stacked cards, real numbers
   wherever there's room, and circles (the lenses of the logo) for people and
   marks. Colour stays in the logo's family: its blue for actions and the
   current place, its blue-to-green gradient for accents, each class's own
   colour on its pages, amber and red only for status. The wording is plain:
   no greetings, nothing chatty. */
