 * User-facing display name for a tranche. Maps `Senior` → `Upper Mezzanine`
 * on Apxium pools (identified by pool name, see `partners.ts`); every other
 * tranche/pool combination passes through unchanged.
 *
 * Call this at the view-model boundary (options, cards, transaction views),
 * NEVER in matching/sorting logic — `compareTrancheSeniority` and
 * `pickDefaultTrancheId` rank by the raw subgraph name and must keep doing so.
 * This is the one function in `domain/` that returns a user-visible string,
 * and it is here rather than in each frontend so all three cannot drift.
 *
 * `pool` accepts the raw `PoolOverview` (`poolName`), the facade `Strategy`
 * (`name`), or the name itself.
