/*
  VxOSJ Design System
  ===================
  Shared visual language for all VxOSJ pages. Load this AFTER w3.css and
  ggapicss.css, and BEFORE font-awesome, so these rules can override w3.css
  defaults where needed.

  <link rel="stylesheet" href="./CSS/w3.css">
  <link rel="stylesheet" href="./CSS/ggapicss.css">
  <link rel="stylesheet" href="./CSS/vxosj-design-system.css">
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

  Color tokens (--brand-*)
    --brand-ink    #0f172a  primary text / dark surfaces
    --brand-blue   #1d4ed8  primary accent / links / buttons
    --brand-cyan   #38bdf8  secondary accent
    --brand-gold   #f59e0b  reserved highlight accent
    --brand-soft   #f8fbff  light page background
    --brand-muted  #516276  secondary/body copy on light backgrounds

  Typography: Lato (body + headings). Use w3.css text-size helpers
  (w3-large, w3-xlarge, etc.) rather than custom font-size where possible.

  Reusable components (class names to reuse on new pages):
    .nav-shell / .nav-inner / .nav-brand / .nav-links / .nav-link / .nav-cta
        Floating pill site header. Pair with the standard nav markup in
        index.html (includes a mobile .nav-mobile dropdown driven by
        toggleFunction()/#navDemo).
    .hero-shell / .hero-badge / .hero-subtitle
        Centered glass card used over a full-height parallax hero (bgimg-1).
    .section-label
        Small uppercase eyebrow label above a section heading.
    .section-card
        White rounded content card used for supporting copy blocks.
    .story-band / .story-content / .story-eyebrow / .story-lead /
    .story-chip-row / .story-chip / .story-cta
        Full-bleed cinematic project sections with a fixed background image.
        Use modifier classes .align-left / .align-right / .align-center to
        position the content card and add a unique id for anchor linking.
    .storyline-strip / .storyline-inner / .storyline-text
        Dark supporting panel for a secondary image + caption under a
        story-band.
    .quicknav-card / .quicknav-icon / .quicknav-title / .quicknav-desc /
    .quicknav-cta
        Compact link cards used for in-page "jump to a section" navigation.
    .site-footer / .footer-inner / .footer-brand / .footer-tagline /
    .footer-links / .footer-divider / .footer-fineprint
        Standard site footer. Keep hosting/legal credit inside
        .footer-fineprint so it stays understated.

  When adding a new page: link the three stylesheets above, reuse the
  header/footer markup from index.html verbatim, and build new sections
  with .section-label + .section-card or .story-band rather than inventing
  new one-off styles.
