/* Polaris modal kit.
   Every dialog in the app uses this look, taken from the Fleet inventory
   equipment editor: a light header with an optional eyebrow and description,
   a quiet borderless close button, a scrolling body and a grey action bar.

   Markup:
     <dialog class="pm-card">                    (or any element that is the card)
       <header class="pm-head">
         <div><span class="pm-eyebrow">Group</span>
              <h2 class="pm-title">Title</h2>
              <p class="pm-desc">One sentence about the task.</p></div>
         <button type="button" class="pm-close" aria-label="Close">×</button>
       </header>
       <div class="pm-body">…</div>
       <footer class="pm-foot">
         <button class="btn btn-danger pm-foot-start">Delete</button>
         <button class="btn btn-secondary">Cancel</button>
         <button class="btn btn-primary">Save</button>
       </footer>
     </dialog>
   A <div> overlay that holds the card takes .pm-overlay for the backdrop. */
