sb-setup — native-first install

This skill is a thin align+verify layer. It does NOT re-implement a bootstrap wizard.

Bootstrap — defer to Storybook

test -d .storybook && grep -q '"storybook"' package.json 2>/dev/null && echo PRESENT || echo NO_STORYBOOK
# NO_STORYBOOK → defer to Storybook's OWN official onboarding. `storybook` is the official npm
# package (@storybook/cli) — not a URL, not bundled or controlled by this skill; the USER runs it.
# This skill ships ZERO runtime dependencies and makes no network calls of its own. See SECURITY.md.
npm create storybook@latest   # installs, then prints follow-up steps for the agent (the official package)
npx storybook skills setup    # 10.6+: the setup prompt to execute (10.4–10.5: `npx storybook ai setup`)

Command names move between Storybook minors — references/storybook-surface.md holds the current ones and the pre-10.6 equivalents.
