Module button_group 

Exclusive settings and page navigation with one keyboard stop per group.

Functions

button_group

A single-choice setting rendered as content-sized segments in a shared frame. The application owns selected and updates it in on_change. Left/Right (or h/l) move the cursor; Return/Space commit the choice.

tab_list

A page tab list with the same restrained visual language and independent tab-list semantics. Use the selected value to render the associated panel. show_shortcuts renders one-based number hints; applications own key bindings.
