% installPythonEnv  Install standalone Python 3.13 and Gemini Robotics ER dependencies.
%   Downloads a self-contained Python distribution (no system Python needed),
%   then installs packages required by geminiClient.py.

%   Supported architectures: glnxa64 (Linux), win64 (Windows), maca64 (macOS ARM64).
%
%   Run once after cloning:
%     installPythonEnv
