صفحه جزئیات موبایل صندلی اداری ارگونومیک

Create a mobile e-commerce detail page for an ergonomic office chair, specifically the "[مدل صندلی]" concept model. The design should feature 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. Use a vertical grid system that combines architectural blueprints with modern office spaces, employing colors like paper white, graphite grey, steel blue, and subtle orange annotations with clear narrow sans-serif and monospace parameter fonts. The first screen should display the product identity with a 3/4 angle view, followed by front, side, back, and top-down auxiliary angles. Illustrate human sitting postures and desk relationships to show scale without indicating specific height suitability ranges. Label the headrest, backrest, armrests, seat cushion, lumbar support, and chair feet by outline without providing internal exploded structures. Showcase office, reading, and brief rest scenarios. The evidence section should only present structural descriptions and sources provided by the user, marking missing items as "اطلاعات باید تأیید شود". The parameter section must include full chair dimensions, seat height range, load capacity, materials, and adjustment items, without guessing unknown values. The packaging section should display the chair body, confirmed accessories, installation instructions, and care information, marking missing accessories as "اطلاعات باید تأیید شود". Conclude with a summary of confirmed structures and a "مشاهده ابعاد و دستورالعمل‌های نصب" note. Ensure every parameter unit, dimension line, and information card is fully filled out. Fictional ergonomic certifications, load-bearing values, adjustment levels, health improvements, patents, or test results are prohibited.
