/**
 * Board Background Persistence End-to-End Test
 *
 * Tests that board background settings are properly saved and loaded when switching projects.
 * This verifies that:
 * 1. Background settings are saved to .automaker-local/settings.json
 * 2. Settings are loaded when switching back to a project
 * 3. Background image, opacity, and other settings are correctly restored
 * 4. Settings persist across app restarts (new page loads)
 *
 * This test prevents regression of the board background loading bug where
 * settings were saved but never loaded when switching projects.
