Create a clean black-and-white coloring-book line drawing on a wide horizontal white canvas. Center the scene on a whimsical hot air balloon floating in the sky, drawn with smooth hand-inked outlines and no color or shading except sparse hatch marks. The balloon envelope is large and rounded with vertical stitched panel lines and a curved bunting garland wrapped across its lower half; the garland has exactly 7 triangular pennant flags with alternating plain and dotted fill textures. Below the balloon, attach a small woven basket with two suspension ropes, and place one smiling child inside, wearing a brimmed hat and scarf, with one arm raised in a friendly wave. Surround the balloon with exactly 4 puffy cartoon clouds: one small cloud in the upper left, one large cloud in the lower left, one medium cloud at mid-right, and one large cloud in the lower right. Add exactly 3 simple flying bird silhouettes shaped like loose curved V marks: two small birds to the left of the balloon and one to the right. Keep the composition airy with lots of blank white space, rounded cute proportions, child-friendly line art, consistent medium-weight black strokes, minimal interior detail, no background horizon, no text, no color, and no watermark. The main subject should feel like {argument name="theme" default="a cheerful child riding a hot air balloon"} in a simple printable coloring page style.
