Korean Sleep Tips Thumbnail

Goal: Create a bright Korean YouTube style thumbnail about improving sleep, combining a lifestyle portrait with bold editorial typography. Canvas: 1200×675 horizontal 16:9 thumbnail, soft warm indoor bedroom/living room background, thin white rectangular border inset from the edges. Main subject: On the right half, show a young East Asian woman with long dark wavy hair wearing an off shoulder cream knit sweater, sitting in a cozy room and touching her cheek with one hand. Her face is intentionally covered by a large centered square blur/mosaic block in muted skin tone colors, obscuring all facial features. Keep the portrait softly lit, feminine, and clean. Layout: Left half is dominated by oversized stacked Korean headline typography with thick white outline and subtle black drop shadow. Use three main headline lines: line 1 black text, line 2 pink text, line 3 pink text. The woman overlaps slightly behind the typography, creating a magazine thumbnail composition. Text content: Include exactly 4 text blocks: 1) a pink brush stroke banner at upper left reading {argument name="top banner text" default="요즘 제가 빠진!"}; 2) the main headline reading {argument name="headline text" default="삶의 질을 높여준 8가지"}; 3) a pink oval brush label near the lower center reading {argument name="callout text" default="꼭 해보세요!"}; 4) a small handwritten note on the right reading {argument name="side note text" default="일상이 달라져요!"}, with the second phrase in pink and underlined. Decorative elements: Include exactly 2 pink outline hearts, one near the top banner and one near the right handwritten note. Include exactly 4 star/sparkle doodles: two white sparkle marks above the headline near the center, one pink star outline on the left edge, and one small white star near the lower callout label. Add hand drawn underline strokes under the callout and side note. Visual style: Korean lifestyle content thumbnail, cute and polished, high contrast, bold rounded sans serif Korean lettering, black and hot pink palette with white outlines, soft beige background, playful brush strokes, clean social media design. Constraints: Do not add extra text blocks, extra people, logos, or watermarks. Keep the face fully obscured by the square blur block while preserving the hair, sweater, hand, and shoulders.
