Tabs was the only component in the library styled with Tailwind utilities, so it could not be themed like the rest and assumed Tailwind was present. It also fired raw CustomEvents instead of declaring outputs, and set a roving tabindex with no keydown handler at all -- which left every inactive tab unreachable by Tab while the arrows did nothing. It now uses wire-* classes and a local style block, declares change and select outputs, and opts into the roving runtime. mode=url mirrors the selection into a query parameter via pushState. Back and forward are handled in the runtime, which activates the matching tab rather than assigning to component state: a popstate listener writing state would be writing after the client function returned, and that write is dropped. The round trip is marked so the component does not push a second history entry for a navigation that came from history. Also anchors Nav submenus so the viewport clamp can pull them back on screen.

WRNexus UI component showcase
The showcase is generated from packages/ui/component-reference.json. It stays
synchronized with the current component source rather than maintaining a second
hand-written catalog.
bun run --cwd examples/component-showcase dev
Open http://localhost:3000.
Detail-page coverage
Every current UI component receives a dedicated detail page with:
- an interactive server-rendered playground for every declared prop
- typed boolean, number, array, and object controls
- public component-tag syntax with single-quoted dynamic WRN expressions
- component-specific production use cases when a profile exists
- responsive fallback examples for every remaining component
- copyable
.wrnsource beside every live preview - complete props, slots, and explicitly declared public events
- live
event.detailoutput for interactive components - previous and next component navigation
The specialized profiles for new and recently repaired components live in:
scripts/showcase-profiles.mjs
Update that file to add product-quality examples or public enum options. Do not infer allowed prop values from implementation comparisons; unrestricted values such as icon classes, labels, IDs, and URLs must remain free-form inputs.
Generated files
The generator creates:
app/layouts/showcase.wrn
app/layouts/document.wrn
app/pages/*.wrn
app/pages/components/*.wrn
showcase-manifest.json
showcase-manifest.json records component, category, demo, prop, slot, and event
coverage and is used by the test suite. Do not hand-edit generated pages.
Validation
After changing UI components, metadata, profiles, the playground, or showcase styles, run:
bun run scripts/generate-ui-component-reference.mjs
bun run --cwd examples/component-showcase generate
bun run --cwd examples/component-showcase test
bun run --cwd examples/component-showcase build
The complete local check is:
bun run --cwd examples/component-showcase check
Review representative component pages at mobile, tablet, and desktop widths and in light, dark, keyboard-only, and reduced-motion modes before publishing.
