/* ============================================================================
   Message Centre — shared sidebar/strip/thread layout used by both the athlete
   portal (athlete-profile.js) and the coach portal (athlete-profile-detail.js)
   via window.MessageCentre.mount(host, opts).

   Mirrors docs/projects/message_centre/wireframe-AP-06-message-centre.html.
   Bubble classes (.acf-msg-out / .acf-msg-in) are reused from
   athlete-condition-feed.css. The .ap-mc- prefix is shared (kept for backward
   compatibility — the rules originated in athlete-profile.css).
