The recovered bottom apron had been represented as one solid collision segment, which prevented the ball from reaching the drain threshold. Split that apron around the visible center drain so a lost ball decrements the ball count and allows player and game-over progression to continue. Add a conservative ball-search impulse after three seconds below the movement threshold. This protects long-running games from other low-energy rests without changing active trajectories, and reuses the original nudge sound as feedback. Test Plan: - `cargo fmt -- --check` -- passed - `cargo test --all-targets` -- passed, including drain and ball-search regressions - `cargo clippy --all-targets -- -D warnings` -- passed - `git diff --check` -- passed
