[Purpose]
Lo-fi BGM video cover for study and work, illustrated editorial YouTube thumbnail with a calm rainy-city atmosphere.
Designed as a familiar study-with-me / ambient beats cover that still feels like a real uploaded video thumbnail: readable title, channel identity, cozy desk narrative, and small clickable details.

[Composition]
- Main scene: {장면 컨셉} as the central narrative, with the desk area occupying about 55% of the frame and the window/city area filling the remaining 45%.
- Subject placement: desk and listening zone slightly lower-left, with the laptop glow, coffee steam, and cat forming a warm focal triangle near the center.
- Background treatment: layered room interior with bookshelf edges, pinned notes, charging cable, rain-dotted window glass, neon reflections, and small signage outside for a lived-in rainy Tokyo night mood.
- YouTube thumbnail layout: integrate a bold title block for {메인 타이틀} in the upper-left to top-center area, supported by {서브타이틀}, a compact channel tag {채널 핸들}, and a view-bait pill reading {시청 유도 문구}.
- Add one soft accent graphic such as a rounded cyan-lilac speech bubble, small coffee emoji-style icon, or vinyl-disc sticker behind the title so the thumbnail feels clickable while staying cozy.
- Keep the desk, laptop, headphones, coffee, notebook, rain window, and cat readable at thumbnail scale, with natural small objects enhancing the scene rather than flattening it.

[3. CORE STRUCTURE]
- Foreground desk zone (bottom 35%): laptop, headphones, coffee cup, small cat, open notebook, pencil, sticky notes, book stack, and a loosely coiled cable arranged as a gentle diagonal from left to right; the laptop screen is the brightest practical object.
- Midground work zone (center 30%): matte wooden desk surface, warm desk lamp spill, playlist card on the laptop screen, subtle waveform graphic, tiny calendar note, and a paper tag showing {업로드 정보}.
- Window zone (upper-right 40%): rainy Tokyo night view with reflected neon signage, soft apartment lights, wet street color streaks, and a few legible tiny shop-sign shapes softened by glass and rain.
- Character/mascot treatment: if a seated figure is implied by {장면 컨셉}, keep it small and secondary to the room atmosphere, wearing headphones or a hoodie silhouette, matched to the classic lo-fi cover language.
- Text system: {메인 타이틀} appears largest, {서브타이틀} below it, {배지 문구} inside a small rounded badge, {채널 핸들} near the lower-left or beside a tiny avatar circle, and {시청 유도 문구} as a warm callout near the laptop glow.
- Style translation: {화풍} should appear as polished 2D illustration with soft cell-shaded edges, subtle gradient shadows, hand-drawn line clarity, and tactile paper grain.

[4. STYLE RULES]
- Typography: use Pretendard SemiBold for Korean and a clean sans serif for numerals, 42–64 px range for the main title, 22–30 px for the subtitle, and 16–20 px for channel/date microcopy, with slightly expanded letter spacing.
- Color palette: draw from {컬러 톤} plus deep navy #1B2333, soft cream #F4EBDD, muted teal #6C98A8, dim neon pink #D97A9A, and warm lamp amber #E0A85A as small accents.
- Border/shadow: soft drop shadow 4px y-offset, 14px blur, 18% opacity for text, stickers, laptop, and desk objects; edge highlights should feel hand-painted rather than glossy.
- Surface texture: lightly paper-like illustration grain, faint brush texture in the sky, raindrop trails on glass, matte tabletop reflections, soft fabric texture on the chair or hoodie, and gentle steam from the coffee.
- Thumbnail readability: emphasize large Korean title hierarchy, strong light-dark grouping around the desk, and recognizable silhouette shapes for cat, headphones, laptop, cup, and window.

[5. VISUAL STYLE]
- Camera / lens: 35mm equivalent, slightly elevated indoor perspective with a gentle wide-angle feel, as if framed for a YouTube thumbnail rather than a full illustration plate.
- Lighting: {시간대} ambient room light from the left window side, cool neon spill from the rainy city outside, and a small warm desk lamp fill from lower-left.
- Color grade: faded amber, cyan, and lilac with restrained contrast, soft blacks, slightly hazy highlights, and a calm editorial thumbnail finish.
- Aspect treatment: compose for {비율}, with important title and face/desk details visible even when cropped by platform previews.

[6. MOOD]
Classic lofi study stream cover — quiet-focus atmosphere, rainy Tokyo night, warm desk routine, coffee steam, gentle cat presence, and a clickable but soothing YouTube music thumbnail mood.

[7. CRITICAL]

- Exact rendered channel handle: {채널 핸들}
- Exact rendered badge text: {배지 문구}
