got a lot of great answers to "how is the shell involved in handling Ctrl+C" to the effect of one of:

- "the shell is responsible for sending a SIGINT"
- "the shell takes input from the terminal emulator and relays it to the program"
- "it must be handled by the layer above the program, which is the shell"

and while none of those is true, they feel like they totally _could_ be true in a different world. It feels hard to explain why it might be useful to have a more "accurate" mental model
