Shift range selection

Hand this to your AI. It names the exact library parts, timings and accessibility promises of this demo.

Build the "Shift range selection" pattern (@codeatlasdev/ui demo #387, inputs/checkbox) in my app.

Call get_demo({ ids: ["#387"] }) first and keep its structure. It needs @codeatlasdev/[email protected].
Use: Lists and tables with row selection that need Shift range selection.

Keep these library parts, with the props and tokens the demo uses:
- Checkbox from "@codeatlasdev/ui"

Behaviour to keep:
- `onclick={(e) => (shift = e.shiftKey)}` is forwarded to the input and runs just before `onchange`
- `onchange={(on) => toggle(i, on)}` applies the state to every row between the anchor and the clicked row when shift was held
- `data-testid="row-{i}"` lands on the native input
- Footer line counts the selected rows

Reduced motion: the demo handles it; keep that branch.
Keyboard: operable; keep the focus order and key handling.

Change only the copy and the data. Use the theme tokens (--ca-*), never raw colours.
