/**
 * lens — the game designer AI lens for programmers.
 *
 * One tool, one door. Given a described situation it returns the matched
 * industry-proven design philosophies — the questions a designer would ask,
 * red flags in code terms, and concrete prescriptions — plus the matching
 * docs from the knowledge base. The KB is fetchable through the same tool
 * via `doc` (+ optional `section`).
 *
 *   { situation: "combat feels flat" }      → matched lenses + matching docs
 *   { lens: "game-feel" }                   → one named lens, full content
 *   { doc: "G106" }                         → a knowledge base doc (TOC-gated)
 *   { doc: "G106", section: "Jitter" }      → just that section
 *   {}                                      → the lens catalog
