Client-by-client behaviour for text-justify

Partial support (4): Gmail, Outlook 365, Outlook (New), Yahoo 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 (8): Gmail Android, Gmail iOS, Outlook Classic, Outlook iOS, Outlook Android, Apple Mail, Apple Mail iOS, Samsung Mail. Plan fallbacks for these clients before relying on text-justify in production sends.

Behaviour unverified in: Thunderbird, HEY Mail, Superhuman.
