## What changed - Probe for screen readers at startup on macOS, Windows, and Linux, with a 450 ms timeout. Include Windows Narrator detection in the current login session. - Save `tui.animations = false` when a screen reader is detected and no user animation preference is configured. Preserve explicit preferences and config comments, and retain a session default if saving fails. - Record the attempt in `tui.screen_reader_detection_done`; either boolean value skips future detection. Allow explicit animation preferences to override the screen-reader default on reload. ## Testing Add tests for one-time detection, timeouts, preference preservation, temporary CLI overrides, persistence failures, and preference reloads. Verify rendering without animation frame requests and interactive startup that records detection without replacing an explicit preference. GitOrigin-RevId: f61c19dfd053f97e8cfed68dce7389fa7601120d
