/* `btn-purple` is used for secondary actions that are deliberately not
   "primary" but still assertive — the incident form's "Re-locate using
   Safe360" is the canonical use, signalling "you're retrying, not
   initiating". Hue matches .status-badge.status-locating so the two
   read as paired UI. */
