Copy-paste vs CLI installation

I've started to prefer copy-paste over CLI-based component installation.

Not because CLIs are bad, but because I value ownership.

With copy-paste:

I know exactly where the code lives.
I know exactly what version I'm using.
I can modify every line.
I don't have to worry about a future library update changing something underneath me.

Six months later, that component is still exactly the code I chose to ship.

With a CLI, you're often trusting another layer of tooling to install, generate, configure, or update things for you.

Give me the source code.

I'll take it from there.

Do you know any other UI library that prioritizes copy-paste over CLI installation?

I'm genuinely curious.
