看台视线：剖面决定的观赛体验

Show the seating bowl of a mid-sized sports venue from within, composed so the sightline geometry is the subject. Render the tiers rising steeply enough that each row clears the head of the row in front, the risers growing progressively taller toward the back so the rake curves rather than running straight — the profile visible along the side of the block where the steps step up. Detail the seats as individual moulded shells on a slim steel standard, fixed to the concrete tread, in two alternating tones. Show the vomitory openings punching through the bank at two levels with lit signage above them and a handrail down the centre of each stair. Detail the front row with a glazed balustrade rather than a solid one so nothing blocks the lowest sightline, and a wheelchair platform integrated at a mid-level with companion seats beside it. Keep the pitch or court visible below, brightly lit, with the seating in relative shadow. Include scattered spectators. Photorealistic, geometric, focused on the rake, view along the tiers.
