Push notifications are live, plus a few smart upgrades:
• Instant push the second a Global Entry, NEXUS, SENTRI, or FAST slot opens at any office you're watching.
• Per-office "alert me before this date" filter — perfect if you already have an interview booked far out and just want a sooner one.
• Pause all alerts with one tap when you don't want to be bothered.
• Already-available offices? You'll get a one-shot heads-up the moment you start watching them.
• Smart cooldowns so a flapping office never spams you.
