/**
 * McIntosh Cast Receiver — P0 Nest Hub instrument face
 * -----------------------------------------------------------------------------
 * Tokens mirror Apple/McIntoshHome/Theme/McIntoshTheme.swift (legend green,
 * meter blue family, chassis black). Keep hex values in sync when retuning iOS.
 *
 * Layout: brand bar → dual meters → meta (title + seat) → whisper nav.
 * Ambient rule: soft blue/green bloom only under meters — Nest is a room lamp.
