/**
 * @file
 * Buttons.
 *
 * Hierarchy of form buttons:
 * - primary: .button--primary, webform submit, first button of .form-actions
 *   (dark red, filled);
 * - secondary: every other form button (.form-submit) – white, outlined;
 * - danger: .button--danger, delete – red outline, filled on hover;
 * - small: .button--small, add-more / upload / remove buttons.
 *
 * Plain .button (links styled as buttons, unclassed <button>) stays a filled
 * neutral button; the link buttons used in content (more, action, download,
 * event, leaflet, tag, success) keep the square IMTM look.
