vendor/autoload.php の事前チェック条件

以下の IF 条件、OR が妥当な気がする。

もしも、AND が妥当な場合、ソースコメントを残したい。

Start with html/define.php at lines 16–20 and inspect the pre-check for vendor/autoload.php. Determine whether the condition should use OR or AND, then make the condition correct or leave a source comment explaining why AND is appropriate; done means the chosen behavior is clearly justified.
