/**
 * Messages hub shared UI — Conversations · Team · Broadcasts · Campaigns
 *
 * Implements the "Kovello messaging UI optimization v2" design handoff:
 * one underline tab bar, a lighter neutral scale, numbered step headers and
 * a single set of stage pills shared by every panel in the hub.
 *
 * The handoff renders the app blue as #1a73e8; we keep the app's own
 * --primary-color (#0d6efd) and adopt the handoff's neutrals and tints.
