/**
 * The one notice a CNY session posts when records had no rate.
 *
 * CNY mode has no fallback, so a model the table cannot price contributes no
 * cost at all; the footer's total is then smaller than the work done, with
 * nothing on screen saying why. This is the one sentence that says it, once per
 * session, and names the two honest fixes rather than picking one: switch to
 * `USD` (Pi's catalog is already per model, tiers included) or state yuan rates
 * under `price.rates`.
 *
 * Pure: the caller has the count, this shapes the answer. No figure is quoted,
 * because there is none to quote.
