[Content]: Add example page for In-Page Navigation feature #312
Description
What content is needed?
Add an example content page to the starter template that demonstrates the In-Page Navigation feature. This should be similar to the existing feature example pages (RTE, Image, FAQs, etc.) and show the feature in action so users can see how it works when they install the template.
Content type
Example page (demonstrates a feature)
Details
The page should demonstrate:
- In-Page Navigation with multiple sections to scroll between
- Sticky navigation behaviour
- ScrollSpy highlighting the active section
- Mobile collapse behaviour
- How it works alongside other features in different layouts
Additional context
The In-Page Navigation feature was added recently with sticky nav, ScrollSpy, and editor-controlled settings. It currently has no example content page in the template.
