/**
 * A Blade comment describes a directive. It never spells one.
 *
 * Blade compiles what is inside `{{-- --}}` as well: the comment is stripped
 * from the OUTPUT, but the directives in it are compiled on the way there. So a
 * comment explaining why the parenthesised php directive was avoided produced
 * exactly the open PHP tag it was warning about — and everything after it in the
 * file was swallowed as PHP source.
 *
 * That failure is silent. No exception, no warning, no missing-view error: the
 * page renders, one block short. The term switch on the order page disappeared
 * this way and the only symptom was a test asserting it was there.
 *
 * Scoped to the forms that open a PHP tag, which are the ones that eat the rest
 * of the file. A comment mentioning @if or @disabled is survivable and there are
 * two of those in the repo already; this is not the place to relitigate them.
