Patch Changes
- c300cfb: Strip React's auto-injected
<link rel="preload" as="image">resource hints from rendered email HTML. React adds one to the document<head>for every<img>during SSR, but email clients ignore preload hints, so they were just noise in the output. Other<link>tags (stylesheets, fonts, user-authored non-image preloads) are left untouched.
