Capturing a long receipt/email in one screenshot: exploit the pinned header

When screenshotting a receipt/email that is taller than the reading pane, one shot rarely shows both the identity (date/subject) and the amount they are at opposite ends. Trick: many mail/reading panes keep a sticky header showing the subject line while you scroll the body. So scroll the body until the fare/total is visible while the subject (which carries the date) stays pinned at top now a single save-to-disk screenshot proves both. Also: after opening a new item, wait ~1s before scrolling; the pane often ignores a scroll issued too fast after load. And expect bank web sessions to idle-timeout (~15-20 min) mid-task, forcing re-login batch the same-site captures together.
