/* ============================================================
   FreeBodyEngine docs theme - a green-phosphor terminal look,
   lifted directly from this project's own kitty/waybar configs
   (~/.config/kitty/kitty.conf, ~/.config/waybar/style.css):
   near-black background, mint-green text, a brighter green
   accent for active/hover states, and waybar's own glow effect
   reused for the active nav/tab item. Self-hosted FreeMono (see
   fonts/NOTICE.md) rather than a Google Font - this engine's own
   default UI font too.
