/* ============================================================================
   CHAT-NWAR overlay — style.css
   Design system: "noir sur blanc, retro-tech, sobre, simple".
   STRICTLY black & white. Sharp corners. 2px black borders. Geist Pixel font.
   One allowed effect: a HARD pixel shadow (3px 3px 0 #0a0a0a), used sparingly
   and driven by --hype so the overlay still reacts to sound — but stays sober.

   OBS Browser Source: the page itself stays fully TRANSPARENT. Only the little
   white message boxes + the thin meter/pill paint over the game.
