/* ==========================================================================
   PlaySheet — "neon arcade" stylesheet (dark-first, no framework, no webfonts)

   The brief: this must read as a GAME site at first glance, not a blog.
   Tools used: near-black canvas, neon cyan/magenta/lime, hard-offset arcade
   buttons, a per-game neon color code, grid + glow textures, scanlines on the
   hero. Body copy stays high-contrast (>= 12:1) because these pages have to
   be read, and Google rewards readable content.

   Class names are load-bearing: build.py emits .card/.k/.game/.thumb/.btn,
   verify.py keys on .ad--live, FAQ is .faq dl/dt/dd. Do not rename.
