annie.pages.tabs

Lazily built tab panels: a tab’s content is built the first time it is opened (UI helper).

Building every tab on each page load used to cost the full Browse first page, the Annotator task, the Dataset config scan and more, before the user had even looked. LazyTabs creates the empty panels up front and fills each one on its first visit.
