Base shadcn/ui adapter #5
Description
Adapter for apps that use shadcn/ui directly (their own copied components). Since shadcn components live in the app, the adapter is created from the app's components: createShadcnAdapter({ Input, Select, Checkbox, … }), with a documented list of the shadcn components it needs, or a shadcn registry item that generates the adapter file. Test it against stock shadcn components.

next-gen(acd7d02).createShadcnAdapter({ Button, Input, Label, … })comes from@javaabu/forms/shadcn. Each slot is built only when its shadcn components are passed, and slots without them fall back to plain HTML. That keeps a partialcomponents/uiusable. The docs list which components make which slots, plus thenpx shadcn addcommand:docs/advanced-usage/shadcn.md.Testing: stock new-york-v4 components are vendored from the registry in
test/shadcn/ui, with only their imports changed. The adapter passes all 19 conformance cases against them, andexamples/shadcn.htmlrenders the demo on them.Decisions:
Select. Search, multiple values, tags and server search use the shadcn combobox (Popover+Command), and its values are submitted through hidden inputs.RadioGroup. The core now syncs radio groups through a registry instead of DOM events, so selecting a Radix button-radio unselects its siblings. The cost is that arrow keys don't move between them. This is documented.
