   BOKAJA DESIGN SYSTEM — product-page.css
   "Creative Warm" product detail page
   --------------------------------------------------------------------------
   Page-specific styles for the digital-product detail page.
   Complements (does NOT duplicate) tokens.css + components.css.

   Load order:  tokens.css  →  components.css  →  product-page.css

   This file styles the markup unique to product-page.html:
     • two-column hero (gallery + sticky buybox)
     • image gallery & thumbnail strip
     • price block, trust row, file-info panel, license accordion
     • tabs (Description / Reviews / FAQs)
     • reviews (rating bars + review cards)
     • related-products grid
     • mobile sticky buy bar + single-column stacking

   Conventions:
     - Mobile-first; min-width media queries layer on enhancements.
     - All color / spacing / radius / shadow / motion pulls from tokens.
     - The product-page markup uses BEM `--` modifiers for buttons & a few
       components that differ from components.css' single-dash naming, so the
       relevant variants are (re)declared here to keep the page self-sufficient.
