## What it is
Sun Valley ttk theme is a modern Tkinter/ttk theme inspired by the Windows 11 (Sun Valley/WinUI) visual style, distributed as the sv-ttk Python package. It lets developers restyle ttk widgets with light and dark modes in just a couple of lines of code.

## Use cases
- make my tkinter app look modern
- apply a windows 11 style theme to tkinter widgets
- add dark mode to a python gui application
- theme ttk widgets with a fluent design look
- switch tkinter between light and dark themes at runtime
- style python desktop gui without changing widget code

## When to choose
- you are building a Tkinter/ttk desktop app and want a modern Windows 11-like appearance
- you need easy light/dark theme switching in a Python GUI
- you want a drop-in theme requiring minimal code changes

## When to avoid
- your app uses only classic Tkinter widgets instead of ttk widgets (only colorscheme applies)
- you need theming for Qt, wxPython, or other non-Tkinter GUI toolkits
- you require deep customization beyond the Sun Valley visual style
