How to replace Blender's builtin CPython with a Miniconda-managed python

Using Blender with Miniconda

If you want to play with Blender scripting but the Python packages it ships with aren't enough, you can replace its built-in Python with your own. Here I give you some instructions to swap in a miniconda-managed environment.

These instructions apply for macOS. YMMV.

1. Install Blender

# If you don't like Homebrew you can just get it from https://www.blender.org/download/

Explainer for init in docker / k8s

The process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels, such as those of Unix, macOS and Windows, to uniquely identify an active process.

In Unix-like operating systems, PID 1 is usually the init[^init-name] process spawned by the kernel and responsible for starting and shutting down the rest of the system.

A process can create child processes using the fork system call. At any arbitrary time, this means processes can be represented by a tree structure. For example:

─┬─ PID 1 (init)
 ├─┬─ PID 2
 │ └─┬─ PID 4

│ └─── PID 7
