1970s Route 66 Polaroid

Create a square 1970s instant Polaroid photograph with a thick off-white border and slightly rounded blackened edges, showing exactly 2 young adult friends standing in front of a sun-faded turquoise vintage Chevrolet pickup truck at a Route 66 roadside gas station in the American Southwest. The left friend leans casually against the driver-side front area wearing a blue denim jacket, light button-down shirt, faded jeans, and a belt; the right friend leans on the hood wearing a dark vintage rock band T-shirt, faded jeans, and a belt. Both have shoulder-length wavy {argument name="hair color" default="brown"} hair and relaxed road-trip body language, with softly blurred faces like an old snapshot. Behind them is a low gas station building with a corrugated roof, old fuel pumps, a visible Route 66 shield sign above the canopy, dusty desert hills and washed-out sky in the distance. Use sun-bleached warm cyan-and-yellow color grading, heavy vintage film grain, slight lens softness, faded contrast, dust specks, tiny scratches, uneven exposure, and a strong yellow-orange light leak blooming from the upper left. Add handwritten blue ink text centered on the bottom Polaroid border reading {argument name="handwritten caption" default="Summer 76"}. Make it feel like an authentic found 1976 vacation photo shot on instant film, nostalgic, imperfect, candid, and weathered.
