28 + * The "Requires PHP" header above makes WordPress refuse *activation* and
29 + * *updates* on an unsupported version, but it is not re-checked when a host
30 + * later moves an already-active site to an older PHP. Without this guard the
31 + * next request would fatal on 7.4-only syntax inside the files required
32 + * below, leaving the site with a white screen and no explanation.
33 + *
34 + * Everything above this point must stay parseable by old PHP — a parse error
35 + * happens before any code runs, so a guard in an unparseable file is dead
36 + * weight. That is also why CF7DoubleOptIn::$logger carries its type in a
37 + * DocBlock instead of a native (PHP 7.4) property type.
