Features and purpose

Visual regression testing for Textual TUI applications using pytest-textual-snapshot. Captures SVG screenshots and compares across test runs to detect visual regressions. Use when: testing visual appearance, detecting layout regressions, testing responsive designs across terminal sizes, verifying CSS styling effects, or setting up CI/CD for visual testing. Covers snap_compare fixture, run_before callbacks, snapshot management, flaky test handling (animations, cursors, timestamps), and CI integration.
