The Quantum Club — Email Chrome Map

The masthead is constant (QC monogram + “THE QUANTUM CLUB”). What varies by audience × mail-class is the FOOTER and the HEADER chip. Every combination the program uses is rendered below with a minimal body, so the chrome is the only thing on display. The full wordmark lives in the footer only.
