You are mapping the obvious, so that it can be avoided later.

$frame

1. List the $n ideas that most people would come up with first for this: the conventional, expected answers. One sentence each.
2. Group these obvious ideas into 3 to 6 abstract categories, each a short label (for example "a reminder service" or "a fee or fine").
3. List 4 to 8 things that typical solutions to this take for granted. Write each as "Typical solutions assume that ...".

Return only JSON, with no other text:
{"ideas": ["..."], "categories": ["..."], "assumptions": ["..."]}
