/*
 * Unified send action treatment.
 *
 * These are the four composer send buttons:
 * - Home image: the form submit button in /static/index.html
 * - Home video: #videoSendBtn in /static/index.html
 * - Create image: #sendBtn in /static/create/index.html
 * - Create video: #videoSendBtn in /static/create/index.html
 *
 * Keep the existing icon-only markup and submission hooks, but give every
 * send action the same white purchase-chip material used by nav-purchase-btn.
