v1.1.8

• Backup recovery now rechecks the wallpaper selection before and during restore, blocks restoring an active wallpaper, and preserves catalogue changes made concurrently.
• Wallpaper activation verifies that macOS applied the requested wallpaper and reports when activation needs attention.
• Import previews stay aligned with the selected video across changes, rotated-video cropping is corrected, and conversion progress remains monotonic.
• Keyboard range selection now starts from the focused wallpaper card.
• The installer handles release checksums and command-line arguments more reliably.
• Expanded regression coverage for catalogue preservation, backup restore, import previews, video geometry, and installation.
