Riveted Roll-Up Metal Cabinet

Generate a 2048×2048 PNG of a single object-only birdhouse disguised as a miniature drift pit garage bay, centered and filling ~75% of the frame on a pure white background. Use a straight-on front view. The roll-up door is 100% fully closed with horizontal slats and decorative side tracks. The real bird entrance consists of two perfectly symmetrical smooth round holes (28.6mm diameter each) positioned evenly in the recessed signage header panel above the door, appearing as clean black voids with soft rounded lips and short internal tube extensions. The roof is a lift-off piece with a boxed awning overhang (~30mm front overhang), drip edge, and slight slope for water shedding. Hidden ventilation slots are under both side roof overhangs. Drainage holes are visible in the floor.
