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.
