/* =============================================================================
   SmartMBX Academy — Storefront brand layer (store.css)
   Loaded AFTER assets/style.css to upgrade the customer-facing store + product
   pages into a premium extension of the WebGL marketing site: deep dark canvas,
   gold gradient accents, Fraunces/Anton display + Manrope UI + JetBrains Mono
   numerals, and tasteful CSS-only hover motion (lift + gold glow).

   CSP-SAFE: this is an external 'self' stylesheet (allowed). All styling is
   class-driven; the store templates use NO inline style="" attributes (which
   the commerce CSP blocks) and NO <style> blocks.

   Font stacks degrade gracefully: if the Google Fonts <link> is blocked by CSP,
   the system fallbacks keep the layout intact.

   BUNDLE-CARD BOOK FAN  (plan/bundle cards on index.php — #plans)
   ---------------------------------------------------------------------------
   A fanned STACK of Vol-I (SPC™) front covers, built by assets/books.js'
   renderBundle() into each <div class="smbx-books" data-bundle="1" …> host that
   tops a .bundle-card. Reuses the verbatim .bk/.cf/.art look (above) at a small
   "fan" size, but lays the covers out as overlapping 2D cards (a hand of cards /
   shelf fan) — no 3D rotateY, SVG art only (cheap, WebGL-free). A fixed-height
   stage keeps the bundle grid's cards aligned regardless of cover count.
   CSP-safe: class-driven; books.js sets only data-* + a .book-fan class. The
   tiny per-cover rotate/offset live HERE in the sheet, not as inline styles.
