// Notifications: a reply or reaction from someone two of your follows
// reported is folded — the row says who it is from and what they did, who
// flagged them, and Show unfolds it — rather than dropped without a trace
// (Adam's phone, 2026-10-14: a reply Amethyst showed was missing here). A
// person one follow flagged, or a stranger nobody did, shows as ever.
// Run: bun tools/notif-report-fold-test.js
