/* ==========================================================================
   Corporate LP Design System v4.3 — Layout & Navigation styles
   ──────────────────────────────────────────────────────────────────────────
   Header / Site Nav, Footer, Tabs, Accordion, Table, Pagination, Breadcrumb,
   Modal, Tooltip. Consumes tokens from `colors_and_type.css`. Class names
   match the production wireframe (`pinrich_corporate_wireframe_v32_rewrite.html`)
   so existing markup ports 1:1 to the design system.

   File layout (LP loads three files now):
     <link rel="stylesheet" href="/path/to/colors_and_type.css">
     <link rel="stylesheet" href="/path/to/assets/components.css">  // form / card / alert / chip / chat-dock / release-notice
     <link rel="stylesheet" href="/path/to/assets/layout.css">      // THIS FILE — header / footer / tabs / table / etc.
     <link rel="stylesheet" href="/path/to/assets/logo.css">

   Scope of this file
   ------------------
   • Header (`.site-header` / `.header-nav` / `.nav-item` / `.nav-cta` / `.nav-login` /
     `.megamenu` / `.hamburger` / `.mobile-drawer`) — sticky top nav (64px = `--height-topnav`),
     megamenu dropdown, mobile hamburger drawer with accordion sub-menus. Includes the
     `body.is-top-page` inverse style for navy hero pages.
   • Footer (`.site-footer` / `.footer-inner` / `.footer-section` / `.footer-link` etc.) —
     dark footer, navy-bg, grouped product links, legal row.
   • Tabs (`.tabs` / `.tab` / `.tab-panel`) — inline tab bar plus mobile-scroll variant.
   • Accordion (`.accordion` / `.accordion-item` / `.accordion-toggle` / `.accordion-panel`) —
     FAQ / feature-detail collapsible blocks.
   • Table (`.table`) — pricing comparison / feature comparison.
   • Pagination (`.pagination` / `.pg-btn`) — News / Press list pagination.
   • Breadcrumb (`.breadcrumb`) — inline breadcrumb for News detail / Press detail.
   • Modal (`.modal-backdrop` / `.modal` / `.modal__header` / `.modal__body` /
     `.modal__footer`) — built on `--popover` tokens.
   • Tooltip (`.tooltip-wrap[data-tooltip]`) — pure-CSS hover tooltip on `--popover` tokens.

   Tokens used (no new tokens added; everything maps to existing colors_and_type.css)
   ---------------------------------------------------------------------------------
     --background / --card / --foreground / --foreground-subtle / --muted /
     --muted-foreground / --primary / --primary-foreground / --primary-hover /
     --primary-soft / --accent / --border / --border-strong / --popover /
     --popover-foreground / --shadow-sm / --shadow-md / --shadow-lg / --shadow-xl /
     --radius-sm / --radius-md / --radius-lg / --radius-full /
     --sp-1..16 / --control-h-md / --control-h-sm / --control-px-md /
     --text-body-sm / --text-body-md / --text-body-lg / --text-caption /
     --text-display-sm / --text-display-md / --fs-subheading /
     --font-weight-medium / --font-weight-semibold / --font-weight-bold /
     --tracking-tight / --tracking-normal / --tracking-wide /
     --duration-fast / --duration-base / --duration-slow / --easing /
     --ring-focus / --height-topnav / --container-content / --page-padding-x

   Naming
   ------
   • Block-level names (`site-header`, `site-footer`, `mobile-drawer`) match the
     wireframe HTML; do not rename.
   • Variants follow shadcn vocabulary where applicable.
