Crate typub_theme 

Theme system for HTML output styling

Provides a unified theming system for all HTML-outputting platforms. Themes are CSS files that can be applied with or without inlining.

Themes are loaded in two layers:

1. Builtins - Embedded at compile time from templates/themes/
2. User themes - Loaded at runtime from user’s templates/themes/ directory

User themes with the same ID override builtins; new IDs extend the registry.
