 * Reply styling — Twitch-flavoured.

 * .reply-header).  Visual treatment:
 *   1. A 3px purple vertical bar runs the full message row height
 *      on the LEFT edge, separating it visually from non-reply
 *      messages stacked above.
 *   2. The body indents slightly to accommodate the bar.
 *   3. A small "↳ Replying to @X" header above the message-meta
 *      mirrors Twitch's "Replying to @..." line.  Useful even
 *      when the @mention is the first token of the message body
 *      because mobile viewers may not scroll up to find the
 *      original message.
 *
 * The bar is positioned via `border-left` on the .message itself
 * (using the .is-reply modifier).  Tip: this DOESN'T conflict
 * with the parent `.messages { padding: 1rem }` because the
 * border lives INSIDE that padding.

   * Mobile split-pane layout — video on top, chat below.
   *
   * History: an earlier version of this query used
   * `.shell { height: auto }` + `body { overflow: auto }`, which
   * made the whole document scroll instead of the messages list
   * scrolling internally — chat input pushed below 200 messages.
   * The first fix put video + chat in a grid with body locked, but
   * set `.stage { max-height: 45dvh; overflow: auto }` which
   * caused the video (with `min-height: min(64vh, 40rem)` from
   * desktop) to be taller than the stage AND positioned BELOW the
   * brand-row + stream-info-form, so it ended up scrolled
   * off-screen.  Streamer reported: "the mobile CHAT looks good
   * however i can no longer see the video at all."
   *
   * Current shape:
   *   - .shell is a flex column (auto stage, 1fr chat).  Stage
   *     gets just-enough height for the 16:9 video; chat gets the
   *     rest of the viewport.
   *   - Video player-card is reordered to TOP of the stage so it's
   *     immediately visible without scrolling.  Brand-row + info
   *     form + meta + controls + diagnostics all stack below the
   *     video; if any of those exceed the stage's natural height
   *     the stage scrolls internally to expose them.
   *   - Player-card's desktop `min-height: min(64vh, 40rem)` is
   *     dropped; aspect-ratio: 16/9 + flex: 0 0 auto handles
   *     sizing.
   *   - Chat keeps its internal grid (header / messages-1fr-scroll
   *     / form-pinned-bottom) so input is always reachable.
   *
   * `100dvh` (dynamic viewport height) handles iOS Safari address
   * bar + keyboard correctly; falls back to 100vh on older
   * browsers (Safari <16, ~2% of mobile users).
