------------------------------+-----------------------------
 When running `npm run build:dev` or `npm run dev` on a fresh clone of
 wordpress-develop, the build fails silently if PHP is not installed
 locally on the developer's machine.

 The Gutenberg build process reads `.min.asset.php` files to generate
 `script-loader-packages.php`. Without local PHP, this step throws
 "Unknown error while reading PHP source file" for every asset file
 and generates empty package files, causing the block editor to fail
 to load in the local Docker environment.

 == Steps to reproduce

 1. Clone wordpress-develop on a machine without PHP installed locally
 2. Run `npm install`
 3. Run `npm run build:dev`
 4. Run `npm run env:start` and `npm run env:install`
 5. Navigate to wp-admin/post-new.php

 == Expected result
 The block editor loads correctly.

 == Actual result
 The block editor fails to load with PHP notices about missing
 dependencies (wp-a11y, wp-i18n, wp-blocks). The root cause is that
 `script-loader-packages.php` is generated with 0 packages because
 local PHP is not available to parse the `.min.asset.php` files.
