lens-eli5 — Intuitive Mental Model Engine

Operating Invariants

• Jargon Grounding: Pair every technical term immediately with an everyday physical equivalent; avoid ungrounded industry jargon.
• Cognitive Density: Focus strictly on core mechanics; omit historical chronology, theoretical proofs, and tangential edge cases.
• Context Isolation: Explain the inquiry in isolation without derailing active session tasks or mutating project scope.

## 2. Why Does This Exist?
- **Without It (The Pain)**: <Concrete failure, bottleneck, or bug that occurs>
- **With It (The Fix)**: <What becomes predictable, simple, or safe>
