The web/admin/space Docker image builds fail at the Vite/PostCSS step with "Cannot find module '@tailwindcss/postcss'". These apps load the shared @plane/tailwind-config/postcss.config.js, which references the @tailwindcss/postcss plugin by name, but the plugin was only declared as a dependency of packages/tailwind-config. The Docker build installs via turbo prune + 'pnpm fetch' + 'pnpm install --offline', which lays out node_modules so PostCSS resolves the plugin relative to the app directory (apps/<app>), where it is not reachable. A plain 'pnpm install' resolves it from tailwind-config's context instead, which is why local builds passed and masked the issue. Declare @tailwindcss/postcss as a direct devDependency of the three apps that run Vite/PostCSS so it is symlinked into each app's node_modules and resolves under the isolated linker regardless of install flow. Verified by reproducing the exact Docker flow (prune -> fetch -> --frozen-lockfile offline install -> build) for admin, space and web: all install in sync and build successfully with full Tailwind CSS output.
