/* Merit's ONE feedback layer: the status modal, the confirmation dialog, the busy lock, toasts, field errors,
   the request progress bar and the error page.

   Markup comes from controllers/errorhandling/templates/globalmodal.html and errorpage.html; behaviour from
   static/javascript/controllers/errorhandling/script.js, which
     - opens #merit-modal, #merit-confirm and #merit-busy with showModal() and, to close, adds .is-closing and
       calls close() on animationend (so every exit here is a CSS animation on the dialog itself),
     - sets data-tone (success | danger | warning | info) on a dialog and draws its icon as
       <svg class="gm-svg"><circle class="gm-ring"/><path class="gm-draw"/></svg>,
     - builds toasts as .toast[data-variant] (.is-in to enter, .is-out to leave, .is-paused on hover or focus,
       duration in --toast-ms),
     - marks fields with .field.has-error + p.field-error + .shake, and toggles #nav-progress.is-active / .is-done.
   Tokens and every shared component come from the theme stylesheet, which loads first. */
