Client-by-client behaviour for right

Fully supports right (7): Outlook 365, Outlook iOS, Outlook Android, Apple Mail, Apple Mail iOS, Thunderbird, HEY Mail.

Partial support (1): Samsung Mail. Expect rendering quirks unique to each engine — partial support typically means a subset of values, an ignored shorthand, or sanitizer-specific rewrites.

No support (6): Gmail, Gmail Android, Gmail iOS, Outlook (New), Outlook Classic, Yahoo Mail. Plan fallbacks for these clients before relying on right in production sends.

Behaviour unverified in: Superhuman.
