Lockfile must be regenerated to fully update postcss to 8.5.10.

The pnpm-lock.yaml contains both postcss@8.5.10 and lingering entries of postcss@8.5.6 (including postcss-import@16.1.1(postcss@8.5.6)). CI will install the old 8.5.6 version unless the lockfile is regenerated.

In `@package.json` around lines 50 - 54, The lockfile contains mixed postcss
versions causing CI to install 8.5.6; regenerate the pnpm lockfile so postcss is
consistently 8.5.10 and postcss-import resolves to the same version. Run the
appropriate lock regeneration (e.g., remove/refresh pnpm-lock.yaml and run pnpm
install) ensuring package.json's devDependencies entries for "postcss" and
"postcss-import" resolve to postcss@8.5.10, then commit the updated
pnpm-lock.yaml so CI uses the updated dependency tree.
