/**
 * Build the whole public site as one deployable tree: the landing page at the root
 * and the docs site under docs/. Used by the Pages workflow and for local preview:
 *
 *   BASE_PATH=/<repo>/ pnpm build:site     # CI (GitHub Pages project subpath)
 *   pnpm build:site                        # local (base "/")
 *   pnpm --filter @prismshadow/penguin-landing preview   # serve the assembled tree
 *
 * Each package builds with its own BASE_PATH (landing: <base>, docs: <base>docs/),
 * then the docs dist is copied into the landing dist under docs/. The result is a
 * single artifact — one GitHub Pages deployment hosts both sites.
