A **tiny, theme‑aware Streamlit component** that adds a one‑click "copy-to-clipboard" button to your app — perfect for the chat UI, URLs or any other text the user might need to copy.

## ✨ Features
- **Streamlit theme aware**: Adapts icon colour & tooltip style automatically; works in both light _and_ dark themes.
- **Two icon styles**: Google *Material Symbols* (default) or the native Streamlit code‑block icon.
- **Custom tooltip & "Copied!" label**: Localised UI in one line.
- **Keyboard‑friendly**: Fully focusable, press **Enter/Space** to copy.

## 🔧 Installation

```bash
pip install st-copy
````

## ⚡ Quick start

```python
import streamlit as st
from st_copy import copy_button

st.title('Minimal demo')

copy_button('Hello, Streamlit!')  # one line – that's it 🎉
```

Run your script:

```
streamlit run app.py
```
