/**
* Slim top bar — animated walking mule on the left over a tiled desert
* backdrop, settings gear on the right. The active heap badge moved into
* the Heaps panel in the left sidebar (where it actually relates to the
* heap rows the user navigates to).
*
* Also hosts the "expand sidebar" affordances: when a side panel is
* collapsed, a small panel-open icon appears on the corresponding edge
* so the user has a way to bring it back without hunting for the
* keyboard shortcut. When the panel is open, the button hides — its
* collapse twin lives in the panel's own header.
