/* Pills are outlined in the site's standard button colour when resting, and

   buttons already use on hover. */

/* The parent theme styles bare <button> elements, including
   `button:hover  { background: rgba(241,78,78,.8) }` and
   `button:active, button:focus { background: #f14e4e }`.
   Those beat a plain class selector, so every state below has to declare its
   own background or the theme's coral leaks through — that focus rule was why
   a clicked pill stayed highlighted until you clicked elsewhere. */
