Explain this at three levels of depth

First contact with a concept, when you don't yet know how deep you need to go.

Explain the topic below three times, each for a different reader.

1. **Curious outsider.** No background assumed. No jargon at all. About 100 words.
2. **Adjacent professional.** Knows the field next door, not this one. Use correct terminology and define each term once. About 250 words.
3. **Practitioner.** Wants the precise version, including the parts the simpler explanations glossed over. Say explicitly what levels 1 and 2 simplified and where those simplifications would mislead someone.

Level 3 matters most. Do not just pad level 2 with jargon.

Topic:

Explaining a concept. Getting an idea across at the depth you need, with analogies, origins and first principles.
