A single, continuous, and complete mobile e-commerce detail page for an ergonomic office chair, with an aspect ratio of 3:7. The product is the "Axis M3 Ergonomic Chair" concept model, featuring a dark graphite grey mesh back, black frame, silver-grey five-star base, visible headrest, armrests, seat cushion, and lumbar support, maintaining structural consistency across all perspectives. The overall design uses a vertical grid system combining architectural blueprints with modern office spaces, featuring paper white, graphite grey, steel blue, and subtle orange annotations, clear narrow sans-serif, and monospace parameter fonts. The first screen shows the identity of the product with a 3/4 angle view; followed by front, side, back, and top-down auxiliary angles; using human sitting postures and desk relationships to show scale without inferring specific height suitability ranges; labeling headrest, backrest, armrests, seat cushion, lumbar support, and chair feet by outline without providing internal exploded structures; showcasing office, reading, and brief rest scenarios; the evidence section only shows structural descriptions and sources provided by the user, with missing items marked "information to be confirmed"; the parameter section includes full chair dimensions, seat height range, load capacity, materials, and adjustment items, with unknown values not guessed; the packaging section shows the chair body, confirmed accessories, installation instructions, and care information, with missing accessories marked "information to be confirmed"; and ends with a summary of confirmed structures and a "view dimensions and installation instructions" note. Every parameter unit, dimension line, and information card must be fully filled out. Fictional ergonomic certifications, load-bearing values, adjustment levels, health improvements, patents, or test results are prohibited.
