• Texture and warmth — Organic elements such as paper wrinkles, handwritten strokes, seals, tapes, etc.
• Handwritten/calligraphy fonts — Especially suitable for note-style, personal sharing scenarios
• Text fills the screen — Xiaohongshu is for mobile vertical screens, text should be large enough to be seen at a glance
• Core element enhancement — Key numbers/keywords as visual heroes (enlarge 3 times, change color, add decoration)
• Clear structure — Main title > Subtitle > List, distinct hierarchy
• Warm tones — Cream color, warm orange, warm gold perform well

• HTML screenshots — Too flat, like PPT templates, no soul (only fallback for precise data tables)
• Cyber neon/dark blue background — Dark blue backgrounds such as #0D1117 are aesthetic forbidden areas
• Signature/watermark — Cover images should not have "花生", "花叔", "@花生"
• Excessive white space — Better to be full than empty

• Theme: What is this content about?
• Core keywords: Which words/numbers need to be made into visual heroes?
• Mood/tone: Suspense? Dry content? Warm? Shocking?
• Number and type of images: Single cover / Carousel set / Infographic?

• Visual style: [One sentence describing the visual sense, e.g. "warm notebook paper + brush calligraphy large text + hand-drawn small icons"]
• Color: [Background color + main color + accent color]
• Copy layout: [Which text to enlarge as hero, which as subtitle, overall arrangement]
• Mood: [First impression of users after seeing it]

1. Each direction has clear differences (at least one of style, mood, color is completely different)
2. Mark recommendations (explain why a direction is recommended based on content characteristics)
3. Copy should be specific (not "enlarge the title", but "the number '28' is a 200px hero element, emphasized with orange")
4. No more than 3 directions (too many choices make selection harder)

Direction A: Handwritten note style (Recommended)

• Visual style: Cream checkered paper background + brush calligraphy main title + hand-drawn technology small icons
• Color: Background #FDF6EC + main color #D97706 (warm orange) + accent circle lines
• Copy layout: "Alibaba C4 Building" and "A group of Cantonese people came" fill the upper half as hero, "AI Open Source Champion" is highlighted in orange as visual anchor, "Qianwen APP" seal at the bottom right corner
• Mood: Friendly, real, like a friend sharing inside information

Direction B: Dark gold reveal style

• Visual style: Dark frosted background + large gold text + badge decoration
• Color: Background #1A1A1A + main color #E2B714 (gold) + white auxiliary
• Copy layout: "Global AI Open Source Champion" giant gold text fills the screen, "Big Factory Inside Information" gold badge at the top, subtitle in white at the bottom
• Mood: Shocking, inside information, sense of weight

• Select one directly → Enter generation
• Request mixing/adjustment → Modify the direction and confirm again
• Not satisfied with any → Ask for preferences and re-propose
