   Palette: bg #0a0a0a, ink #dfdfdf, accent #e8632a, muted #666
   Font: GCAkihiko (from fonts.css)

   Device mockup: each thumbnail is framed inside a minimal laptop/monitor
   shell — dark aluminum bezel, 3-dot traffic-light bar (::before), 16:10 screen
   with object-fit cover, and a slim deck/base beneath (::after).
   All frames are identical so the grid reads unified regardless of source AR.

       ::before                     — top chrome bar with 3 traffic-light dots

       ::after                      — slim deck/stand beneath the screen
