/* ============================================================
   BackTheme — Mockups
   Load order: 1 tokens > 2 base > 3 components > [4 mockups] > 5 sections

   Every product visual on the site is built here in CSS. There are no
   screenshots and no image assets, which is why the visuals re-theme
   with the colour mode, stay sharp at any pixel density and cost no
   extra requests.

   Contents
     1. App window        .backtheme-mock
     2. Skeleton bars     .backtheme-skeleton
     3. Floating chips    .backtheme-float-card
     4. Code window       .backtheme-code
     5. Phone             .backtheme-phone
     6. Technology wall   .backtheme-tech-wall
     7. Product screens   .backtheme-screen   (CricoScore / BongoKhata)
     8. Storefront        .backtheme-store, .backtheme-thumb
     9. Entrance animations  .backtheme-animate-*
    10. Portfolio previews  .backtheme-web-preview, .backtheme-phone-preview

   The .backtheme-animate-* classes stay idle until `.is-visible` lands
   on the owning .backtheme-reveal ancestor, so a screen plays once when
   its card scrolls in rather than looping off-screen forever.
