Rewrite README: lead with Python solver, not C++ binaries

- Intro now describes both backends (NumPy/CuPy + C++ binaries)
- Remove Colab reference and Binder badge (dead)
- Remove transducer walkthrough (too specific for README)
- Add uv run example and "no GPU required" note
- Simplify mission statement

-This project is a Python implementation of v1.4.0 of the [MATLAB toolbox k-Wave](http://www.k-wave.org/) as well as an
-interface to the pre-compiled v1.3 of k-Wave simulation binaries, which support NVIDIA sm 5.0 (Maxwell) to sm 9.0a (Hopper) GPUs.
-
-**New in v0.6.0:** Unified `kspaceFirstOrder()` API with a pure NumPy/CuPy solver. See the [API guide](https://k-wave-python.readthedocs.io/en/latest/get_started/new_api.html). The `kspaceFirstOrder()` API is experimental and may change before v1.0.0.
+A Python implementation of [k-Wave](http://www.k-wave.org/) — an acoustics toolbox for time-domain simulation of acoustic wave fields. Includes a pure NumPy/CuPy solver (`backend="python"`) and an interface to the pre-compiled k-Wave C++ binaries (`backend="cpp"`) with NVIDIA GPU support (sm 5.0–9.0a).
 
 ## Mission
 
-With this project, we hope to increase the accessibility and reproducibility of [k-Wave](http://www.k-wave.org/) simulations
-for medical imaging, algorithmic prototyping, and testing. Many tools and methods of [k-Wave](http://www.k-wave.org/) can
-be found here, but this project has and will continue to diverge from the original [k-Wave](http://www.k-wave.org/) APIs
-to leverage pythonic practices.
+Increase the accessibility and reproducibility of [k-Wave](http://www.k-wave.org/) simulations for medical imaging, algorithmic prototyping, and testing.
 
 ## Getting started
 
 ![](_static/example_bmode.png)
 
-A large [collection of examples](../examples/) exists to get started with k-wave-python. All examples can be run in Google Colab notebooks with a few clicks. One can begin with e.g. the [B-mode reconstruction example notebook](https://colab.research.google.com/github/waltsims/k-wave-python/blob/HEAD/examples/legacy/us_bmode_linear_transducer/us_bmode_linear_transducer.ipynb).
+A [collection of examples](../examples/) covers common simulation scenarios. Run any example locally:
+
+```bash
+uv run python examples/ivp_homogeneous_medium.py
+```
 
-This example file steps through the process of:
- 1. Generating a simulation medium
- 2. Configuring a transducer
- 3. Running the simulation
- 4. Reconstructing the simulation
+No GPU required — all examples run on CPU with NumPy.
