   Keyed to the CONTENT container, not the viewport. The same 1280px window
   gives the grid a different width depending on whether the rail is expanded,
   and a viewport breakpoint cannot tell those apart - it would reflow the grid
   whenever the sidebar is toggled at a fixed window size.

   Each threshold is the width below which that row's narrowest cell stops
   being usable, not a device size.
