RattleSnake
A warm, paper-toned VS Code theme. Burnt brown drives the primary syntax highlighting (keywords, functions, types); dark baby blue is used for secondary highlights (strings, constants, class/type names, selections/brackets, links).
Includes light and dark variants that share the same palette roles, plus structural highlighting for Python: class and function bodies get a subtle card-style background with a dashed brown top/bottom border, docstrings get a translucent blue wash, and self/cls are colored to match parentheses.

Python structural highlighting
extension.js (bundled in this same extension, activates on Python files) adds:
- A translucent background + dashed brown top/bottom border around every top-level class and function body.
- A translucent blue background behind docstrings.
Development
- Open this folder in VS Code.
- Press
F5 to launch an Extension Development Host with the theme and highlighting installed.
