   VzdelAI — Layout & Component CSS
   -------------------------------------------------------------
   Tento súbor obsahuje VŠETKY layoutové, komponentové a
   responzívne pravidlá. Brand tokens (farby, fonty, premenné)
   sú v <style> bloku v index.html — design system.

   Štruktúra (vyhľadaj komentárové banery):
     1. Reset, body, scroll-padding
     2. Skip link (a11y)
     3. Layout shell — .vz-container, .vz-section
     4. Hero — .vz-hero, animované blobs, neural lines
     5. Nav — .vz-nav-row, .vz-nav-links, mobilné menu
     6. Karty a gridy — .vz-grid-3, .vz-card-pad
     7. Activities row — .vz-activity-row hover
     8. Outputs grid — 12-col, .vz-output-card
     9. Consortium — .vz-partner-card, .vz-partner-media
    10. Stats band — .vz-stat-card, layered background
    11. Footer — .vz-footer-top, .vz-funding-grid
    12. Roadmap rail (HowItWorks) — .vz-roadmap-*
    13. News (zatiaľ nepoužité) — .vz-news-card
    14. Tweaks panel overrides
    15. Fluid typography clamps
    16. RESPONZIVITA — media queries (zoskupené na konci)

  /* ====== BULLETPROOF HORIZONTAL CONTAINMENT ======
     Three layers, because mobile browsers handle each one slightly
     differently and any one of them can leak:
       1. html + body — clip + force width 100%
       2. #root       — same, clips the React tree
       3. overscroll-behavior-x — kills the rubber-band "swipe" gesture
          mobile browsers do even when there's no real content to scroll
          (the slight left/right wobble users feel is this bounce,
          not actual horizontal overflow).
     Use `overflow-x: clip` where supported (no scroll container, so
     position: fixed nav still resolves to viewport); fall back to
     `hidden` for older browsers. */
