/* =====================================================================
   IN-ROUND CHAT — speech bubbles, not a chat window.

   The whole point of this file is that chat NEVER costs you a swing:
     - #chat-stack and every descendant is pointer-events:none, so a swipe
       that starts on a bubble still reaches the canvas underneath. There is
       deliberately no tap target here; history lives in the HUD menu.
     - #chat-bar (the typing surface) is the one exception — it IS interactive,
       and while it's open canSwing() is gated off in game.js so a stray
       gesture can't fire a shot behind the keyboard.

   Anchored under the scorecard by anchorChat() (inline `top`), same trick
   anchorMatchBoard() uses, because the scorecard's height moves with the
   viewport.
