/*
 * PD-1328: Communications > Inbox reply composer (desktop).
 * The message thread is the main content: the list always keeps at least 55%
 * of the conversation pane (a 56% track, so borders and rounding never dip under
 * 55%; never under 240px); the reply box takes at most what is left and scrolls
 * internally, with Send kept visible. The composer starts collapsed to a
 * single "Reply…" bar (communications-inbox-reply-collapse.js).
 * Scoped to #communications-reply-box / the inbox mailbox only: the CRM
 * customer workspace reuses .communications-reply-box but not this pane.
 * Loaded after admin-email-box.css so the editor override wins by order.
 * Phones (<=720px) keep the always-visible composer and is-composer-focused.
