// AlertInbox: what needs someone, worst first. A swipe to the right acknowledges an alert and// a swipe to the left offers to snooze it, each by a flick or a pull past a third of the row, and// a short pull springs back. A tap on a row opens the same two with their words, for// anyone who does not swipe, and arrow keys do it from the keyboard. The badge counts what is// waiting and nothing else: it goes down at once on either, goes up as a snooze runs out,// and follows alerts that arrive or go. A slip is one Undo away; the Done tab reopens one later.////   component Oncall() {//       state kept = load_alert_state()          // a server fn//       <AlertInbox alerts={rows} now_ms={server_now} saved={kept} on_change={(s) => { save_alert_state(s) }}//                   on_ack={(id) => { ack(id) }} on_badge={(n) => { tab_badge = n }}/>//   }//// alerts: each { id, severity, title, body?, source?, at?, snooze? }. severity: "critical",// "warning" or "info" ("error" and "high" count as critical, "medium" as warning, others// as info). at: when, as a date-time or milliseconds. snooze: false for one that may not be put off.// One with no title or a second with the same id is left out. now_ms: the time in milliseconds,// for the server's picture;
