/**
 * Match Chat + Open Ranked — PESBUL arena styling.
 *
 * Built to sit inside the ELO hub's card language rather than beside it: the same
 * dark glass panels, the same cyan accent, the same rounded geometry. A chat that
 * looked like a WordPress comment form would announce itself as bolted on.
 *
 * Mobile is not an afterthought here — most players coordinating a match are on a
 * phone. Bubbles cap at 82% of the column, the composer is a full-width row, and
 * nothing has a fixed pixel width, so the panel never pushes the page sideways.
