On a phone the menu stayed open over the page after a link was tapped, and only the hamburger closed it. It now closes
on any navigation, on a persona switch, on a tap outside it (a dimmed backdrop) and on Escape; its height is capped at
the screen's (dvh) with its own scroll, and its width follows a narrow screen. The hamburger has a name ("Menu") and says
whether the menu is open. The header's logo is a link home and the persona's picture a 44px link to Settings (it was
30px). From md, the sidebar scrolls on its own when the window is short, as on a phone held sideways.
