Compose, Reply and Forward work offline. Drafts are kept on the device (IndexedDB, lib/scheduled.ts), with files attached offline; Send becomes "Schedule" and puts the message in a new Scheduled folder. When the server is reachable again, scheduled messages are sent through the normal outbox (Undo offered for a single one) and offline drafts become server drafts — files uploaded first, each step recorded so nothing is created or sent twice, under a Web Lock so two tabs never send the same message. Drafts written offline show in Drafts as "On this device". Sign-out sends what is scheduled, then wipes the device's copy. Also: offline failures from keyboard shortcuts show "Not available offline"; no recipient suggestions are asked for offline; a reply no longer quotes an error page when the original is not saved. The undo countdown counted to the server's deadline on the browser's clock, so a few seconds of skew showed (18 s instead of 10). /send now also returns undo_seconds, and the composer counts down from that.
