Create a square anime-style CD jacket cover illustration for a sentimental Japanese school rock ballad. The scene shows a beautiful teenage girl standing on a cherry-blossom-lined path outside a school campus at golden-hour sunset, turned slightly back toward the viewer with a calm, wistful expression. She has very long flowing black hair, soft red-brown eyes, pale skin, and wears a frilly ivory blouse with ruffled sleeves and a layered pale lavender-gray skirt, giving a romantic gothic-lolita school-uniform feeling. She holds a glossy black electric guitar with chrome hardware and a shoulder strap across her body, the guitar angled diagonally in the lower right foreground. Cherry blossom branches fill the upper left and top edge, with pink petals drifting through the warm orange air; the background includes a school gate, fence, trees, and softly blurred school buildings bathed in sunset light. Use highly detailed painterly anime rendering, warm cinematic lighting, delicate linework, emotional album-cover composition, rich peach, coral, amber, and rose tones, soft depth of field, nostalgic atmosphere, and subtle film-grain texture. Add exactly two visible text elements in elegant Japanese typography: the large title {argument name="album title" default="放課後の約束"} placed on the left side in translucent deep red, and the smaller artist name {argument name="artist name" default="朱内 愛"} below it. Keep the text integrated like professional music cover art, with no extra logos, borders, track lists, or watermarks.
