/* ===========================================================================
   killpipe — one stylesheet for the whole site.

   Home and TV defined the canonical look (dark #0E1014 body, accent green
   #22CC77, Inter-style sans-serif). Every page — home, games index, each
   individual game, TV — uses *this* file and only this file. Inline CSS
   in a page is reserved for that page's unique gameplay/board surface
   (the math-path grid, scramble's letter cells, etc.), nothing chrome.

   Token names follow the historical retro.css scheme so existing class
   references keep working. Short aliases (--bg, --text, --accent…)
   resolve to the same values for new code.
