1. Custom Background Status

• 1.1 Show uploaded custom backgrounds as the active background in the profile settings header metric.
• 1.2 Render the selected built-in preset as a clearly labeled fallback while an uploaded background is active.
• 1.3 Preserve fallback preset selection so removing the uploaded background restores the selected built-in desktop.

2. Verification

• 2.1 Add focused rendering coverage for uploaded-background labeling.
• 2.2 Run focused frontend tests.
• 2.3 Run scripts/check-structure.sh.
• 2.4 Run openspec validate fix-custom-background-status --strict.
