Forced dark mode

Preview forced dark mode rendering in Chrome to catch algorithmic color inversions and contrast regressions before launch.

These inversions are common in many Android email clients, including Gmail, Samsung Mail, Yahoo, K-9, and GMX.

Use this alongside light and dark mode captures to validate text readability, brand colors, and CTA visibility.
