# Dev and production get deliberately different behaviour here.
#
# Production: vendor/ is baked into the image by the `build` stage of the
# Dockerfile and there is no source bind-mount. Running `composer install` at
# boot is never correct - if /var/www/html is empty or masked by a mount there
# is no composer.json to install from, composer exits non-zero, `set -e` kills
# the entrypoint, and `restart: unless-stopped` turns that into a crash loop
# that never reaches PHP-FPM. Fail loudly with an actionable message instead.
#
# Development: the project directory IS bind-mounted from the host, so vendor/
# is legitimately absent on a fresh checkout and installing it here is the
# convenience that makes `docker compose up` work with no host PHP toolchain.
