Miniatura YouTube Dieta con Katsudon Giapponese

Bright, high-impact Japanese YouTube thumbnail design about diet-friendly eating with a split composition. Left half: white background with oversized bold Japanese headline text stacked diagonally. Top line reads "カツ丼" in vivid orange with a thick white outline and subtle drop shadow; below it reads "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; bottom line features a gigantic red-orange "5" with white outline beside "選!" in dark brown with a white outline. Comic-style emphasis lines and yellow sparkle accents surround the text. Lower-left corner features a flat vector illustration of a smiling woman from the waist up, wearing a yellow tank top with brown hair in a ponytail, giving an OK hand gesture, over a pale yellow circle. Right half: close-up, appetizing food photography of a katsudon bowl under warm lighting. Ceramic bowl with blue vertical stripes, topped with sliced golden-brown breaded pork cutlet simmered in egg and onion over rice, glossy glaze, visible gentle steam, and a fresh green herb garnish. Upper-right corner has a circular white badge with a dotted yellow border reading "おいしく楽しく♪ 賢くコントロール!" in handwritten Japanese script. Bottom section: a full-width pale cream horizontal bar containing 5 evenly spaced circular icons with Japanese captions: a salad bowl ("バランスの良い食事"), a scale ("カロリーを意識"), a walking figure ("適度な運動"), a water glass ("水分をしっかり"), and a clock ("食べる時間を工夫"). Commercial graphic thumbnail style, bold outlined typography, cheerful health-oriented colors, and strong visual contrast.
