Streamlit copy‑to‑clipboard button component

Streamlit Copy-to-Clipboard Button Component

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

import streamlit as st
