Plan step 37 review. The Vite test counted each of four files' plain root rule, which the minifier folds into one even when a build repeats the whole stylesheet: it passed against the Workbench's Tailwind entry, which repeated 231 rules. It now asserts that no innermost rule repeats under the same at-rules, which that build fails and a deduplicating one passes, and it builds a second entry shaped like an application's — outside the package, the foundation, then four component stylesheets that each import button.css, and button.css again — where button.css must also keep its first position. The fixture config refuses to run without DEDUP_OUT_DIR, so it never writes into the package tree.
