The square Wizards source artwork has substantial transparent margins. The compact block slot previously shrank the entire canvas, making its visible logo smaller than adjacent wide logos. Mobile PR 670 enlarges only the image frame while preserving the 60x32 slot, row height, text alignment and contained aspect ratio. No artwork, other logo placements or backend records are modified.

The verified 2400px artwork alpha bounds span vertical pixels 513-1886. A focused regression failed when the first expanded frame crossed the compact slot border; the final 58x52 frame at y=-11 keeps those bounds within its 30px inner height. All four focused logo tests pass. Lint/typecheck passed; the full suite before the final frame refinement passed 2,476 tests with 11 existing skips.

Native visual confirmation and Maestro remain unperformed. The change requires a mobile build containing the PR; no server restart or asset replacement helps an old installed build. Personal build artifacts are not committed.
