// Notifications: a zap on your Zapstore app listing (kind 32267) reads
// "zapped your app PAFF" and opens the app's Zapstore page. It opened the
// zapper's profile: Zapstore's receipt carries no a tag (only the zap request
// inside it does), so the row looked like a zap on nothing (Adam, 2026-11-07:
// "clicking this franzap zap notification keeps bringing me to his profile").
// A row saved before reads the receipt once on tap and goes there too.
// Run: bun tools/notif-app-zap-test.js
