Image 1 (OFFICIAL): The reference/ground-truth screenshot of the original app.
Image 2 (RECREATED): A screenshot of a recreated version of the same app.

Visual aspect to evaluate: {aspect}

Compare the two screenshots and rate how faithfully the recreated app reproduces the visual aspect described above.

Focus on:
- Layout and positioning of UI elements
- Text content and formatting
- Colors, icons, and visual styling
- Overall visual similarity for the specified aspect

Rate on a scale of 1-10:
  1-2: Completely different, no resemblance
  3-4: Major differences, some elements recognizable
  5-6: Moderate similarity, layout roughly correct but notable differences
  7-8: Good reproduction, minor visual differences
  9-10: Near-perfect match, only trivial differences (antialiasing, font rendering)

Be lenient on minor pixel differences, font rendering, and antialiasing — focus on functional visual equivalence.
