// Wave 2B — OFFSEASON HUB · FuturesBoard. Source + helper asserts. Futures are
// TRACKED, NOT GRADED — the board carries that label, never renders a grade,
// self-hides on an empty feed, and colors movement per the contract
// (shortening→green / drifting→amber / flat→dim) — NEVER red for a drift.
