   style.css — CYBERPUNK 2077 theme for azrulcode.com

   This is CSS, not JavaScript, but it's where the whole "look" lives:
   the neon yellow/cyan/red palette, the scanlines, the glitching title,
   and the angular "notched" panels.

   HOW THE COLOURS WORK (important for the JS too):
   The accent colour is stored in two CSS variables, --accent and
   --accent-rgb. Everything accent-coloured references those variables,
   so when main.js changes them (the colour picker), the ENTIRE site
   recolours instantly. --accent-rgb holds "r, g, b" numbers so we can
   build translucent colours with rgba(var(--accent-rgb), 0.5).
