   auto-placement ENTIRELY — with only 2 remaining items (activity bar, main
   column) and no explicit placement, auto-placement packs them into columns
   1 and 2, leaving .main-col stuck in the (now 0-width) middle column while
   column 3 sits empty. Explicit grid-column keeps every child in its own

   Scoped to min-width so it can NEVER win a specificity fight against the
   narrow-screen drawer rules below (body.sidebar-hidden .shell-mid has
   higher specificity than a plain .shell-mid override, so without this
   guard it would keep applying its 3-column value even under 760px,
   racing the drawer layout depending on which selector happens to be more
