Headless treeview with 9 sub-components: Root, List, Item, Activator, Content, Cue, Group, Checkbox, Indicator. Built on createNested for tree state management with selection, open/close, and activation. Exposes --v0-treeview-depth CSS custom property on each item for consumer-driven indentation. Cue self-hides on leaf nodes via hasContent signal from Content. Indicator follows existing CheckboxIndicator pattern with data-state visibility.

…gister Ticket select/unselect/toggle were pointing to createGroup's non-cascade versions. Override them after group.register() so TreeviewCheckbox clicks propagate to descendants and update ancestor mixed states.
Settings panel demonstrates activation, functional toggles/selects, disabled categories, depth indentation via CSS variable, and recursive rendering. Removes file-explorer and selection live examples.
…rops Also fix generate-api.ts to extract @example tags in the ts-morph fallback path used by components with external types files.

Create reusable useRovingFocus composable for roving tabindex pattern with linear and grid navigation modes. Wire into Treeview for full WAI-ARIA tree keyboard nav: arrows, Home/End, Enter, Space, *. - useRovingFocus: manages focusedId, isTabbable, step with disabled skip, optional circular nav, orientation + grid (columns) support - createNested: add el to NestedTicket, add visibleItems() for depth-first traversal of open nodes - TreeviewList: creates roving focus, handles all tree keyboard mappings including ArrowRight/Left for expand/collapse/parent - TreeviewItem: captures el ref, consumes roving for tabindex - TreeviewActivator/Checkbox: remove independent tabindex (now -1), keyboard handling moved to tree container level
Add renderless Treeview.Checkbox with cascade selection to the basic example. Demonstrates keyboard Space to toggle selection alongside arrow key navigation and Enter to expand/collapse.
