/*
 * Reading and accessibility (Plugmind Calm), for the support portal and the operator panel: the same choices as the
 * Operator and Help Desk apps (Settings > Reading and accessibility). Each is a class on <html>, set from this
 * browser's saved choices before the page is drawn (Support/Reading.php), so nothing flashes; reading.js has the panel.
 *
 *   ndc-r-scaled + --ndc-r-scale   text size, on top of the browser's own
 *   ndc-r-font-atkinson / -opendyslexic
 *   ndc-r-spacing                  more space between lines
 *   ndc-r-contrast                 darker text and borders (lighter in dark mode)
 *   ndc-r-motion                   no animations or transitions
 *   ndc-r-calm                     calmer ticket view (reading.js)
 *
 * SupportPal's CSS is in cascade layers, so these plain rules win over it without !important, except where it uses
 * !important itself.
