The four transactional emails on boas.dev v3.4.0. The house signature reaches
the medium through a pre-rendered procedural band (feTurbulence edge + ordered halftone +
Bricolage wordmark, rasterized from the live system — email has no SVG/filters). Buttons are sharp
bracketed consoles, not pills; data sits in instrument readouts. Each frame is the real
sendable HTML; drop-in {{TOKENS}} preserved.
