-- Iteration 7b: WO-E304 borrow escapes, using CONTAINER values (`multi Text`).
-- A class value that escapes is demand-promoted to traced, so the illustrative
-- escapes must be containers, which are owned and never promoted. Mirrors the
-- run/borrow-escape-return corpus case (a class escape, now legal).
