ภาพประกอบย่อของอาหารญี่ปุ่นคัตสึด้ง

Create a bright, high-impact Japanese YouTube thumbnail about diet-friendly eating, in a clean split composition. The left half is a white background filled with oversized bold Japanese headline text stacked vertically and diagonally for maximum readability: the top line says "カツ丼" in huge vivid orange with a thick white outline and soft drop shadow, below it "食べても" in dark brown, then "太らない方法" in hot pink with a white outline and a yellow underline swoosh, and at the bottom a gigantic red-orange "5" with white outline next to "選!" in dark brown with a white outline. Add small yellow sparkle accents and comic-style emphasis marks around the headline. In the lower left corner, place a simple flat illustration of 1 smiling woman from the waist up wearing a yellow tank top, brown hair tied back in a ponytail, making an OK hand gesture, set over a pale yellow circle. The right half shows a close-up, appetizing katsudon bowl photographed in warm light: 1 ceramic bowl with blue vertical stripe patterns, filled with sliced golden-brown breaded pork cutlet over egg and onion on rice, glossy sauce, visible steam rising, and 1 small green herb leaf garnish on top. In the upper right corner, add 1 white circular badge with a dotted yellow border containing the Japanese text "おいしく楽しく♪ 賢くコントロール!" in a friendly handwritten style, with yellow accent marks around the badge. Along the entire bottom, include a pale cream horizontal information strip with 5 circular icons and 5 labels separated evenly from left to right: 1 salad bowl icon with the text "バランスの良い食事", 1 scale icon with "カロリーを意識", 1 walking person icon with "適度な運動", 1 glass of water icon with "水分をしっかり", and 1 clock icon with "食べる時間を工夫". Use a glossy commercial thumbnail aesthetic, warm food photography, thick outlined typography, cheerful health-themed colors, and strong contrast optimized for social media click-through.
