This PR:

• feat(checkbox): add indeterminate state

checked, value, and defaultChecked accept boolean | 'indeterminate'; onChange keeps emitting a boolean, so a {...field} spread still round-trips. Toggling from indeterminate emits true. The default/panel kinds render a dash glyph, surface renders the new Minus icon, and kind="switch" renders indeterminate as unchecked. Includes a minor changeset.

QA

• Verify the Inputs/Checkbox › Indeterminate story: "Select all" shows the dash with a partial selection and checks/unchecks every option on click
• Confirm the dash glyph for default, panel, and surface kinds in both light and dark themes, including disabled
• Confirm existing checked/unchecked stories (Default, Surface, Panel, Switch, FormField) render and toggle as before
• Verify the new Icon › Minus story renders

Testing

• bun run typecheck — pass, by hand
• bunx vitest run --project unit src/stories/checkbox src/stories/icon — 88 passed, by hand
• bunx biome check on changed files — pass, by hand (repo-wide bun run lint fails on pre-existing Combobox.tsx and biome.json schema issues on main)
• New indeterminate tests: aria-checked="mixed" for default/surface/panel kinds, click emits true, value alias, uncontrolled defaultChecked, no checked container class, switch renders unchecked
• not run: visual check in Storybook — not done in this session

Risk

Low — additive API on one component; existing boolean usage is unchanged.

• Blast radius: Checkbox rendering and onChange for all consumers
• Rollback: revert the PR

🤖 Docs audit — no documentation drift detected.

No documentation updates needed — the Checkbox indeterminate change's in-scope doc impacts (AGENTS.md component inventory, public/llms.txt usage line) were already updated within the change itself, and no other in-scope doc states any fact the diff contradicts.
