The fix for Gmail iOS
Inline all CSS instead of using external stylesheets
The engine still flags this in the fix: Gmail iOS inverts every colour in dark mode, dark backgrounds included: #6d28d9 and the other dark backgrounds turn light, and their light text turns dark. It ignores @media (prefers-color-scheme: dark), so CSS cannot opt out.
<div style="max-width: 600px; margin: 0 auto;">
<div style="background-color: #6d28d9; padding: 32px;"></div>

<link rel="stylesheet" href="styles.css" />
