 Nothing nests. `swarm.js::sortedContainerRows` returns every container
 in alphabetical order, full stop — the SW4RM list is a flat roster, no
-indent, no joint, no continuation bar. This used to be a real forest
-walk (`buildAgentTree`, keyed on each container's `parent` field) with
-a DOM-painted `.tree-prefix` indent ladder. Once containers stopped
-carrying a `parent` field entirely, every container became a root and
-the tree machinery could only ever produce this same flat order — so
-we removed it rather than keeping code that draws a tree with one
-level.
