/**
 * CAPABILITY: `.doWhile` — run a body, then repeat WHILE a condition holds.
 *
 * The condition is checked AFTER each pass, so the body always runs at least
 * once (`core.logic.dowhile`). That is the difference from `.loop()`, which
 * iterates a collection it already has.
 *
 * The container publishes NO data output. Carry results out through a `.var()`
 * written from inside the body with `{ updates }` — here `page` advances the
 * cursor and doubles as the loop's own state. `limit` caps iterations (1–10,000;
 * blank means the platform default of 10,000), and `body.break()` works exactly
 * as it does in `.loop()`.
 *
 * Generic scenario: page through a meteor-shower sightings feed until it ends.
