+- Full i18n: every UI string via typed `t()` keys with interpolation;
+  English + Czech locales, language select in settings
+- Uptime bar strip + latency chart on monitor detail
+- iframe embed widget and generic JSON-path widget (backend fetcher)
+- Custom accent color, wallpaper URL, and custom CSS in settings
+- PWA: manifest, icons, minimal service worker
+- Alert transports: webhook, Slack, Discord, Telegram, Gotify, ntfy, SMTP
+  (stdlib `net/smtp`); transport picker + test button in settings
+- Per-monitor alert rules: consecutive-failure threshold, latency warn, mute;
+  per-domain cert-days threshold and mute
+- Per-container CPU/memory in `dash-agent` (Docker stats when socket present);
+  optional SMART, ZFS, and GPU collectors (exec-or-sysfs, skipped when absent)
