/* ============================================================
   security.html — page-scoped styles.
   This page previously depended on common.css (base theme) and a
   ruckosplatform.css link that no longer resolves to a file on disk
   (renamed to oldruckosplatform.css). index.css also has rules that
   target this page's markup directly (its .hero-layout comment even
   says "used by pages with no diagram column (e.g. security.html)"),
   but index.css's card/section theme colors are the old purple
   (#667eea/#764ba2/#f093fb) — superseded later in that same file by
   a blue/orange override for .service-card/.card-icon, matching the
   blue/orange theme used everywhere else already migrated (ruckos,
   gitops, observability). Built from oldcommon.css (base) +
   oldruckosplatform.css (hero, buttons, section head, card grid),
   trimmed to only what this page's markup uses.
