v2.0.2 — clearer syntax roles

Syntax colours and examples became easier to distinguish across twelve languages.

Highlights#

• Reassigned syntax hues using measured perceptual distance so keywords, operators, types, decorators, comments, and errors scan more clearly.
• Added worked token-coverage examples for twelve programming and markup languages.
• Corrected preprocessor directives, Rust attributes, and documentation-comment rendering.
