/*!
 * future-css -- split button
 *
 * A default action joined to a menu of alternatives: Send / Send later, Merge /
 * Squash and merge. Two real buttons, because they are two actions with two
 * accessible names; one button with a hot zone would give a screen reader one
 * name for both.
 *
 *   <div class="fc-split-btn" role="group" aria-label="Send">
 *     <button class="fc-btn fc-btn--primary fc-split-btn__action" type="button">Send</button>
 *     <button class="fc-btn fc-btn--primary fc-btn--icon fc-split-btn__toggle" type="button"
 *             aria-haspopup="menu" aria-expanded="false" aria-controls="send-menu"
 *             aria-label="More send options">
 *       <span class="fc-split-btn__chevron" aria-hidden="true"></span>
 *     </button>
 *   </div>
 *   <div class="fc-menu" id="send-menu" role="menu" popover>…</div>
 *
 * Colour, size and every interaction state come from `.fc-btn` and its
 * variants; this file only joins the pair. The menu is `fc-menu` with its
 * binding, which owns `aria-expanded` and focus. Load this file after
 * `button.css` (the bundle does), since the joined corners override the
 * button's own radius at equal specificity.
