// Mobile: the right-rail FAB is stacked ABOVE the tree FAB and opens the right
|
|
// rail (TOC + page widgets) in the full-viewport Overlay (overlay.js). It only
|
|
// appears when the rail actually has content — runs after toc.js has had a
|
|
// chance to populate the rail (script order in page/main.html), so an
|
|
// otherwise-empty rail shows no FAB. Hidden on desktop by .fab CSS.
