Append `(server activation pending — feature dormant until maximus-api
/v1/prices ships)` to the price-fetching entry under [0.9.0] (#160) to
document state at release time. Add a new [Unreleased]/Changed entry
recording that /v1/prices went live in production on 2026-05-05.
Smoke run against prod with a premium token + manual e2e in dev build
are runtime acceptance criteria handled outside this PR.
