/* ==========================================================================
   SyTech Multipage — Shared Stylesheet
   Single source of truth for nav, footer, and shared base styles across
   all SyTech multipage pages. Page-specific styles remain in each page's
   inline <style> block (which loads AFTER this file, so per-page overrides
   still win).

   What is in here (byte-identical / visually-identical across all 6 pages):
   - CSS variables: 8 common tokens (--navy, --deep-navy, --gold, --amber,
     --light, --white, --soft-white, --text-body)
   - Universal reset, html/body, .container, a
   - .skip-link + :focus
   - Navigation: .nav, .nav-shape, .nav-inner, .nav-logo, .nav-links,
     .nav-links a (hover + ::after underline), aria-current="page" rules,
     .nav-cta + hover, .nav-hamburger + states, mobile breakpoint @1024px
   - Footer: .site-footer, .footer-grid, .footer-brand, .footer-col,
     .footer-bottom + footer-grid mobile breakpoint @900px

   What is NOT in here (kept inline per-page due to real per-page
   differences — see Kit's extraction report for details):
   - Extra :root vars: --dot-blue (index only), --gold-soft / --navy-soft
     (index + about only)
   - .nav-logo class (used by inline SyTech orbital-ring logo on ALL 12 pages —
     SVG-less logo via the <a><div>...</div></a> pattern)
   - .page-hero, .section, .section.alt (not on all pages; per-page padding
     varies; index uses different .hero pattern)
   - .btn-primary (padding + letter-spacing differs between index, contact,
     and the simple-page set)
   - .cta-strip (background color differs — services uses var(--navy),
     others use var(--deep-navy); index does not use .cta-strip at all)
   - All component styles (.feature-card, .diff-card, .case-card, etc.)
