Formación

• 3–8 years of professional web development experience in frontend or full-stack work.
• Fluency across web eras, including legacy layouts.
• Command of hand-written HTML and CSS: semantic markup, flexbox, grid, media queries, and legacy layouts.
• Browser DevTools as muscle memory.
• Command-line comfort: unzipping archives, standing up a static local server, and fixing broken image references.
• Enough JavaScript to read a page's scripts and understand their DOM impact.
• Professional written English for task justification.

Responsabilidades

• Render a reference page and two candidate replications at 1920×1080, and judge which is closer.
• Diff visual fidelity in detail: box model, typography, color, borders, images, z-order and overflow.
• Read source of attempts and grade construction quality, distinguishing correct replication from appearance-only accuracy.
• Test responsiveness and identify defects like a navbar collapsing at 1400px.
• Provide evidence-cited justifications for all preferences with concrete examples.
• Apply the "this task is broken" escape hatch when appropriate.
