storybook-setup

Prerequisites:

1. Confirm Storybook exists (package.json, .storybook/). If not, switch to /storybook-init.
2. Storybook must be at least 10.6. (While 10.6 is unreleased, next satisfies this — 10.6.0-alpha.x. Any canary build, 0.0.0-pr-*, also qualifies.) If it is older, or upgrade/repair is needed first, switch to /storybook-upgrade, but only if the user explicitly approved a Storybook upgrade.

Run npx storybook skills setup from the project root (or the Storybook package in a monorepo).

Follow the printed Markdown precisely. Do not substitute your own plan.
