Role Responsibilities
Render a reference page and two candidate replications at 1920×1080. Judge which is the closer reproduction, state by state.
Diff visual fidelity in detail: box model and spacing, typography (family, size, weight, line-height, letter-spacing), color and border treatment, image and asset handling, z-order, and overflow.
Read the source of both attempts and grade construction quality. Distinguish a replication that is genuinely correct from one that merely looks correct at one viewport.
Test responsiveness. Identify defects such as a nav bar that looks right at 1920px but collapses at 1400px.
Write specific, evidence-cited justifications for every preference.
Provide detailed explanations like "B nests the article body in a single absolutely-positioned div, so the text overlaps the footer below 1600px, while A uses normal document flow."
Use the "this task is broken" escape hatch with judgment. Distinguish a task that genuinely cannot be completed from one that is merely hard.
