/* -----------------------------------------------------------------------------
 * NATDRIP pulse bar · v2 · universal drop-in
 *
 * Legit live status bar (not a thin ribbon). Label + heartbeat + level word +
 * activity count + tap-to-claim. Never exposes raw amounts.
 *
 * Include on any page:
 *   <link rel="stylesheet" href="/natdrip-pulse.css">
 *   <script src="/natdrip-pulse.js" defer></script>
 * -------------------------------------------------------------------------- */

/* Reserve space for the bar from the FIRST paint so page content doesn't jump
 * when JS attaches the bar. This eliminates the "slow-loading" perception
 * caused by post-render layout shift. */
