A transcript's ``── Wed Aug 12 ──`` does exactly what a grouped list's heading does — it pins to the top row while its day scrolls under it, and ^PgUp/^PgDn step by it — but it was drawn muted, which reads as chrome and put the one landmark in the scrollback below the messages it labels. It takes the accent every other section heading in the app wears. The rule above the compose line keeps its grey: that one really is chrome.
