Sandbox pages that exercise sidebar nesting and page features.
These pages exist to verify navigation behaviour, not to document anything.
The sidebar demonstrates two different shapes, both driven by meta.json:
- Separator sections — written as
"---NAME---"followed by"...folder". The folder’s pages are spread flat under a heading and are always visible. - Collapsible folders — the folder listed by name only, e.g.
"nested". It renders with a chevron and can be opened and closed.
Examples itself is a collapsible folder, and Nested Folder inside it is a second
level that opens independently.
