Produce OOH — Out-of-Home Spec Builder

3 agents (concept → spec-and-legibility → critic) turn a message into an OOH-ready brief + render manifest: one idea, legible in 3 seconds at distance/speed, specced to the placement's real dimensions and production constraints. Like produce-asset, this emits a brief + render-ready prompt + manifest — it holds no API keys and renders no pixels (an operator-connected engine does that via references/_shared/execution-fork.md). Method: references/agent-manifest.md.

Core question: Read at 60 mph from 200 feet in under 3 seconds — does one message land?

Critical Gates — load first

1. One message. OOH is a single idea — a brand, an offer, or a line. Two messages = zero messages.
2. The 3-second read. Legible at the placement's real viewing distance + speed. ≤7 words is the working ceiling for a highway board.
3. Contrast + scale over detail. Big type, high contrast, minimal copy; no small print, no QR-as-the-CTA on a moving placement.
4. Brand-anchored. FORSVN: Forest Shadow / Leaf accent, matte, no gradients/glass; the brand reads even at a glance.
