/**
 * Login / forgot / reset gate.
 *
 * Every rule is scoped under #pa-gate so it reliably wins over the active
 * theme's element styles (e.g. h1 { font-size: clamp(2rem, 5vw, 3rem) }).
 * Loaded as a real stylesheet (not inline) so HTML/CSS optimisers can't strip
 * or defer it out of the cascade.
 *
 * @package StKlara\ProtectedAreas

/*
 * Pin the base font size on the gate page. The theme intends body = 1rem
 * (its SCSS sets it), but on this PHP-rendered gate the WordPress global-styles
 * fluid rule (body = clamp up to 20px) wins instead, so the whole page — footer
 * included — inherits an oversized base. "html body" (0,0,2) beats both single
 * "body" rules regardless of load order. Only loaded on the gate page.
