I get that “beginner guide” might sound helpful to some, but framing it that way feels a bit dismissive. I’ve rebuilt this kind of system more times than I can count, each time learning from mistakes and real-world constraints. It’s not a toy project—it reflects a lot of iteration, nuance, and scars. Calling it “simple” or “beginner” is a bit like walking into someone’s house and saying, “Nice little place you got here”—maybe not meant to offend, but still pretty reductive.
