   phones keep exactly the layout they always had. Below this width, none of

   phone-width column floating in a sea of empty background -- not a desktop
   layout, just a mobile one with padding. This replaces that with real
   desktop treatment: a wide centered shell, an inline top nav instead of
   full-width stacked tab buttons, multi-column card grids so several
   tasks/events are visible at once instead of one long single column, and a
   centered dialog instead of a mobile bottom-sheet for the add/edit form.
