feat(home): build complete homepage and global templates

Scaffolds all components needed for the home and ships a working
front-page implementation covering the 9-section wireframe.

Components (assets/css/components.css)
- 13 sections per Design Handoff section 3:
  buttons, links, forms, cards (5 variants), stat callouts, header,
  nav, mega menu, drawer, footer, hero, logo strip, eyebrow,
  section title/lead, conversion banner, scroll reveal.
- All token-driven, prefixed `av-`, BEM-light. Mobile-first with
  768/1024/1280 breakpoints. Respects prefers-reduced-motion.

Global templates
- header.php: sticky header (60px mobile / 72px desktop), 5-item
  nav, language switcher, primary CTA, mobile drawer with hamburger
  toggle. Skip link first focusable element.
- footer.php: 5-column dark footer (Solutions, Industries, Why
  Asterion, Why Asterion, Newsletter), bottom strip with legal
  links + social.
- index.php: archive/search/blog fallback rendering posts in
  card-blog layout.
- front-page.php: full home with 9 sections, EN copy lifted
  verbatim from PDF Strategie D.1:
    1. Hero "Your Last Mistake Should Be in VR." + 2 CTAs
    2. Trust bar (placeholder logos + 4 inline metrics)
    3. Solutions: MY / FLEX / ACADEMY (3 cards)
    4. Industries: Police / SF / Military / Firefighters (2x2)
    5. Feature heroes: UWeD, Instructor Cockpit, AAR (alternating)
    6. Featured case study with 3 stat callouts
    7. Testimonials (3 quote cards)
    8. Latest insights (queries `post`; placeholder when empty)
    9. Conversion banner (Demo / T&E / Quote)

Verified: HTTP 200 on http://localhost:10004/, 73 KB HTML, 418 ms.

Outstanding (deferred)
- Hero video master + photographs (see MISSING-ASSETS.md)
- Mega menu content (links currently flat to section index)
- Form posts (newsletter currently no-op POST)
- Bricks license activation (manual, requires user key)
- WPML setup wizard (manual, requires user key)
- Lighthouse + axe full audit (visual env required)
