Patch release. Bug-fix and polish window on top of the v2.4.0 baseline.

Fixed

Streamlined the copy-paste code in component-docs previews. The Show-Code panels on /components/sparkline, /components/charts-apex/sparklines, /components/accordion, /components/breadcrumb, /components/button, /components/hover-card, /components/icon, /components/input, /components/popover, /components/qr-code, /components/scroll-to-top, /components/spine-aware, /components/toast, and /components/tooltip now compose WireKit primitives — <x-wirekit::stats> + <x-wirekit::stat> (with the sparkline slot), <x-wirekit::card> + <x-wirekit::card.body>, <x-wirekit::grid>, <x-wirekit::row>, <x-wirekit::stack>, <x-wirekit::prose>, <x-wirekit::text>, and <x-wirekit::heading> — instead of hand-rolled <div> layout scaffolding. The rendered previews are unchanged; the code you copy is cleaner, shorter, and consistent with how the library is meant to be composed.
Accessible names on read-only example inputs in the docs. Several read-only example inputs — the popover share-link / share-URL fields plus a couple of search / filter fields elsewhere in the docs — now carry an aria-label, so screen readers announce them instead of an unnamed text field (WCAG 4.1.2).
