   v2.5.250: help-mode toggle + button hint labels.
   The "?" button in the top-bar toggles `body.help-mode`. When on,
   every button (and button-styled link) with a `title=""` renders
   its title as a small inline label below the button. Operators
   can discover what every control does without hovering — useful
   on touch devices where native hover tooltips don't fire.
