/* ==========================================================================
   C4 Fire & Security . /security-integration/
   Scoped stylesheet for page-security-integration.php.

   Every selector is prefixed .si- and every rule is scoped under .si-page,
   so nothing here can reach another template.

   Tokens come from style.css :root. Global .container / .section /
   .section__header / .label / .h1 / .h2 / .h3 / .btn are reused, not redefined.

   MOBILE RULE, learned the hard way on 2026-07-27: grid tracks use
   minmax(0, 1fr), never 1fr. A bare 1fr is minmax(auto, 1fr), so one wide
   child (a table) sets the min-content floor and clips every sibling. That
   defect clipped ~59% of body text on every table-bearing blog post. Any
   wide content here scrolls inside its own overflow-x container instead.
