   PHONE (≤600px)

   The planner already had the right bones for this: one day at a time via
   .sp-daytabs, a flex row of lanes with min-width, and a sticky time column.
   So the phone version is mostly a matter of committing to them — lanes get a
   fixed width and snap, the inspector stops being a side rail and becomes a
   bottom sheet, and the chrome collapses to one row.

   The one behaviour change is in the JS: drag-to-create can't work on touch
   (the same gesture scrolls the grid), so a TAP on empty lane space creates a
   30-minute block instead. See laneDown/drawUp.
