 - docs: add runtime and JSON examples for toggling style markup parsing
 
 ### Notes
-
 - `Auto` currently uses a conservative rule: if `NO_COLOR` exists, ANSI is disabled; otherwise ANSI is enabled
 - inline style markup supports both short close `</>` and named closing tags like `</red>`
 - unknown or invalid inline tags currently fall back to plain text and do not raise formatter errors
