catafest/colab_google — reverse-engineered prompt

Build me a Google Colab notebook playground repo that feels like a personal lab for trying lots of small Python and AI examples. I want a bunch of separate notebooks, each one focused on one clear test or mini tutorial, like checking GPU and TPU access, using TensorFlow or PyTorch, working with Google Drive and authentication, simple data and image tasks, web automation, audio and video experiments, language models, diffusion image generation, gradio demos, CUDA examples, and a few IMDB and dataset examples.

Please keep each notebook short, runnable, and easy to understand in Colab, with install cells when needed and quick notes about what the notebook is testing. Add a simple README that lists what every notebook does so I can browse the collection easily.

This does not need to be one polished app, it should feel like a real set of working Colab experiments for learning and testing. If package setup has changed, look up current docs online and make the notebooks work with modern Colab.
