feat(child-theme): scaffold asterion-bricks v0.1.0

Initial child theme structure inheriting from Bricks parent. Token-driven,
RGPD-native, mobile-first foundation ready for component and template work.

What's in this commit
- style.css: WP theme metadata (Template: bricks, v0.1.0)
- functions.php: enqueue cascade tokens -> utilities -> components,
  defer-loaded main.js, font preload, theme support, image sizes
  (av-hero 2400x1350, av-card 800x600, av-thumb 400x300), Gutenberg
  default styles dequeued
- theme.json: Gutenberg color/typo palette mirroring tokens
- assets/css/tokens.css: full design system per Design Handoff section 2
  (brand colors, neutrals, semantics, type scale + line-heights, 8pt
  spacing, radii, shadows, z-index, motion, prefers-reduced-motion)
- assets/css/utilities.css: modern reset + .av-container, .av-skip-link,
  .av-sr-only, .av-stack, .av-section helpers, opinionated heading scale
- assets/css/components.css: index of planned components + buttons
  (5 variants x 4 sizes per Design Handoff section 3.1) and links
- assets/js/main.js: vanilla skeleton with header scroll, IntersectionObserver
  reveal, count-up, mobile drawer; respects prefers-reduced-motion
- inc/cpt.php: register_post_type case_study (slug /customers/) + scenario
  (slug /scenarios/) + shared 'industry' taxonomy
- inc/seo.php: Organization JSON-LD on home; placeholders for Product,
  Article, FAQPage, BreadcrumbList
- assets/fonts/: Inter Variable + Italic WOFF2 self-hosted (RGPD; no
  Google Fonts CDN). Inter Display @font-face commented — Inter 4+ uses
  opsz axis from the same file.

Out of scope (intentionally deferred)
- Component fills: cards, forms, navigation, alerts, modals, tabs (placeholders)
- Page templates: home and beyond
- Bricks JSON template exports
- Schema.org Product / Article / FAQPage / BreadcrumbList implementations
