Comprehensive guide for porting UI components from R's bslib package to py-shiny. Use this skill when: (1) User asks to "port this feature" or "port a component" and mentions bslib or links to a bslib PR (e.g., github.com/rstudio/bslib/pull/...), (2) Porting a new component from bslib to py-shiny, (3) Adding a new input, output, or UI component that exists in bslib, (4) Implementing feature parity with bslib, (5) Working on bslib-related features or components. Covers the complete workflow including understanding source implementation, creating Python equivalents, vendoring assets (SCSS, CSS, JavaScript), creating tests, documentation, and all necessary project files.
