doc-prd

Purpose

Create a Product Requirements Document (PRD) — Layer 2 of the SDD flow. A PRD defines product features, personas, success metrics, and acceptance criteria at the C4 Container level (what the product does, not how).

Layer: 2 (Container level). Upstream: BRD. Downstream: EARS → BDD → ADR → SPEC → TDD → IPLAN → Code.

One PRD per BRD iteration cycle (MVP → PROD → new MVP). New scope gets a new PRD; link cycles with @depends: PRD-NN.
