/* No line between the header and the page.
 *
 * There is no border drawn anywhere — the "line" is an overlap. The timeline
 * is positioned at `calc(header-height - 34px)`, so it begins 34 pixels above
 * the header's bottom edge and content scrolls up into that gap and vanishes
 * behind an opaque bar. That vanishing edge is what reads as a divider.
 *
 * Starting the timeline at the header's real bottom means nothing ever passes
 * behind it, so there is no edge and nothing to see.
