/**
 * Phase 3 mobile — gestures listed in USER_JOURNEYS.md §17 as **planned**.
 *
 * These tests are marked `test.fixme` so they appear in the report (as
 * pending, not failing) until the feature ships. Each test contains the
 * exact assertion that should pass once the gesture is wired — flip
 * `test.fixme` to `test` when implementing.
 *
 * Why ship the tests now? They document the *contract* — the next person
 * to wire the gesture has a green/red signal instead of needing to invent
 * an interaction model.
