Masterful Watercolor Manga Locked Room Page Masterpiece

Goal: Create a watercolor manga page in a vertical comic layout about three anime girls trapped in a gloomy closed room, with Japanese speech text. Canvas: Portrait page, approximately 2:3 aspect ratio, off white paper texture, hand painted watercolor and ink line art, soft washes, visible panel borders, no digital UI, no watermark. Layout: Use exactly 4 comic panels: (1) top left small panel, (2) top right small panel, (3) one large central panel spanning the width, and (4) a narrow bottom reaction strip. Keep the page reading like a Japanese manga, with vertical speech balloons. Characters: Show exactly 3 girls. Girl A is a confident purple haired girl with long curled hair, a side braid, green eyes, cat ear like black silhouette behind her head, wearing a shiny gold sleeveless turtleneck; she looks angry and sweaty in the top left panel and appears again as an intense close up in the bottom strip. Girl B is a cheerful blonde bob haired girl with purple eyes, wearing a red frilled coat and a dark green scarf; she raises one fist triumphantly in the top right panel. Girl C is a quiet black haired girl with very long straight hair and red eyes, wearing a loose green dress; she sits barefoot on the floor in the central panel, knees bent, one hand near her lips, looking thoughtful and worried. Panel details: Top left panel has a dark bluish background and Girl A speaking with frustration. Top right panel has a bright yellow starburst background with sparkles, Girl B smiling confidently, and a red Japanese sound effect near the top. The large middle panel shows Girl C seated in a dim, concrete or stone walled room with a vertical metal pipe on the left, cold blue gray shadows, and a small bright window or opening at the right casting pale light. The bottom strip shows only Girl A’s narrowed green eyes and purple hair against a red background, emphasizing suspicion and irritation. Text content: Include exactly 5 vertical Japanese speech balloons and 1 red sound effect. Top left panel has two speech balloons: {argument name="top left speech one" default="もう一ドヤって場合じゃないよ！"} and {argument name="top left speech two" default="こんな不気味な所に閉じ込められて……入り口、塞がってる!!"}. Top right panel has one speech balloon: {argument name="top right speech" default="わははっ！ほら、入れるって言ったっしょ！さあ、手がかりを探そう！"}. Middle panel has one speech balloon: {argument name="middle speech" default="脱出も大事だけど…それより犯人、まだいるかもよ？"}. Bottom strip has one speech balloon: {argument name="bottom speech" default="ったく……いっつも後先考えないんだから……"}. Add the red sound effect 「ドヤ!」 in the top right panel. Visual style: Delicate shoujo manga faces, expressive eyes, thin ink outlines, watercolor gradients, slightly uneven hand painted panel edges, soft paper grain, dramatic color contrast between the cheerful yellow top right panel, cold blue gray central room, and red bottom reaction strip. Constraints: Count and show exactly 4 panels, exactly 3 recurring characters, exactly 5 speech balloons, and exactly 1 sound effect. Keep all dialogue vertical Japanese text, but do not add extra captions or additional text.
