* Fix outline for headings that have links
Previously produced blank items because it assumed any link in a heading is an anchor
* Filter unlisted items from overviews
Previously they were filtered only when the card was rendered, so their heading was still shown
* [Overview] Add id to group headings
* Hide headings from empty groups
Should never happen but you never know
* [Overview] Ensure "Other" is always last even when no sorting
- Sidebar, overview listings, breadcrumbs now based on actual parent-child relationships, rather than increasingly outdated heuristics
- parent properties are now generated automatically from the URL structure, and need only be specified to override that default
- Ability to group by page hierarchy in overview pages, where pages that have >= 2 children become categories
Smaller improvements:
- More flexible syntax for specifying the params of overview pages
- [Overviews] Hide group heading if only one group is present
- parentItem and parentUrl properties that can be used on any page
- Alias a collection as the children of a page (useful for "virtual" parents like Layout)
- Do not error if a page card icon is missing
- Add ids, use ids to link copy button. No need for client-side script or updating the copy button manually for dynamic code snippets.
- Add button to link to code block
- Slight refactor on copy plugin to use the 11ty API properly
Turns out `prettier-plugin-organize-imports` sorts imports differently than the old one so this will prevent spreading the change across multiple commits whenever we touch a file (and potentially introducing conflicts)
* Simplify how list of components is exposed to 11ty
No need for functions or computing multiple times, that's what data is for!
* Add attributes to component data
* Cleanup
* Add slug (tagName without wa-)
* Add component reference / cheatsheet
