/**
 * Test bootstrap for the flex-objects plugin.
 *
 * The media endpoints live in classes/Api/FlexApiController.php, which extends
 * the API plugin's AbstractApiController and uses its HandlesMediaUploads trait.
 * So three autoloaders have to be wired up:
 *
 *   1. This plugin's own autoloader  → Grav\Plugin\FlexObjects\*
 *   2. Grav core's autoloader        → Grav\Common\* / Grav\Framework\* (+ PHPUnit)
 *   3. The API plugin's autoloader    → Grav\Plugin\Api\*
 *
 * In a real install all three are siblings under user/plugins; for a symlinked
 * development clone we also fall back to the workspace layout. Set GRAV_ROOT to
 * override discovery, e.g. `GRAV_ROOT=/path/to/grav composer test`.
