Content drawn under the title separator touched the line on every standard screen, because listStart() == headerH() (the row right after the separator). Graphical screens worked around it with a hand-rolled hdr+2. Bake a 2px breathing gap into listStart() so every list gains it at once, and switch the screens that hand-rolled the offset (Compass, Nav, Nearby detail) to listStart() so the content top is computed the same way everywhere.
