Maity: Board

web: more vertical room in the top bar when it shows only the logo and the right-hand buttons

Oliver (seq 14881, screenshot att-2qcf5zv9c2tn, join page): when the top bar shows only the logo and the buttons on the right (e.g. the theme switch), the bar is too low and logo and buttons touch its lower edge. Give it a minimum height / padding so they sit with room above and below, the same as in the full bar. Check every page that uses the reduced bar (join, invite, sign-in, legal pages) in light and dark. Smoke/e2e as usual.
