- Switch package manager from npm to yarn 1.22.22 (pinned via packageManager,
matches PressV/sp-ui-kit): remove package-lock.json, add yarn.lock (v1).
- Add "vite" as an explicit devDependency. npm 7+ auto-installed it as a peer of
@vitejs/plugin-vue / @tailwindcss/vite, which masked the missing declaration; a
clean `yarn install` (no peer auto-install) needs it explicit or the tsc build
fails to resolve 'vite' / 'vite/client'.
- README: npm -> yarn (+ `corepack enable`).
