# Design QA — Pochette MusicLand Playbacker

- Source visual truth: `/Users/sacha/Library/Containers/net.whatsapp.WhatsApp/Data/tmp/documents/AC89FF71-250F-4949-9D82-F89EE91CF735/PHOTO-2026-07-28-13-57-44.jpg`
- Supplied base asset: `/Users/sacha/Projets/MusicLand/src/assets/UI/musiclandPlaybackCover.png`
- Implementation screenshot: `/Users/sacha/Projets/MusicLand/design-qa-assets/musicland-cover-preview.png`
- Side-by-side comparison: `/Users/sacha/Projets/MusicLand/design-qa-assets/musicland-cover-comparison.png`
- State: deterministic cover with a profile picture, artist name `username`, and `PLAYBACKER`
- Viewport / output: square cover at 1024 × 1024 px
- Density normalization: the 894 × 890 px source photo was cropped to its 661 × 661 px cover region, then normalized to 1024 × 1024 px. The implementation output is native 1024 × 1024 px at density 1.

## Full-view comparison evidence

The comparison places the normalized source on the left and the deterministic implementation on the right. The MusicLand artwork, central profile-photo placement, artist-name hierarchy, `PLAYBACKER` label, rounded corners, palette, and square composition align with the supplied target.

## Focused-region comparison evidence

The full cover is the focused component for this request, so a separate crop was not needed. The critical regions remain clearly readable at 1024 px:

- top MusicLand brand;
- central circular profile picture inside the supplied ring;
- artist name below the profile picture;
- `PLAYBACKER` label at the bottom.

## Required fidelity surfaces

- Fonts and typography: white, light sans-serif text matches the reference hierarchy. Long artist names use a smaller server-side size and the app preview scales the text to one line.
- Spacing and layout rhythm: the profile, artist name, and bottom label follow the same vertical order and approximate positions as the source.
- Colors and visual tokens: the supplied blue-purple-pink artwork is reused directly without recoloring or recreated gradients.
- Image quality and asset fidelity: the supplied PNG is used as the source asset. The final server output is rendered at 1024 × 1024 px. The profile image is center-cropped and circularly masked.
- Copy and content: `MUSICLAND`, the selected artist name, and `PLAYBACKER` are the only cover content.

## Findings

No actionable P0, P1, or P2 visual mismatch remains.

## Comparison history

1. Initial output placed the artist name and `PLAYBACKER` too high and too large.
2. Font sizes and vertical positions were adjusted.
3. The revised side-by-side comparison shows the intended hierarchy and spacing.

## Residual test gaps

The in-app browser blocked local `localhost` navigation during QA, so the surrounding step-2 screen could not be captured there. The web bundle completed successfully, and the actual deterministic cover renderer was executed locally to produce the implementation evidence above.

final result: passed
