Infocard Generator

Quick Start: Analyze content (density × structure × mood) → Auto-sense tone for color palette → Pick a layout skeleton → Embed HTML directly in Markdown with <style scoped>.

Critical Rules

Rule 1: Direct HTML Embedding

IMPORTANT: Write info cards as direct HTML in Markdown. NEVER use code blocks (```html). The HTML should be embedded directly in the document without any fencing.

Rule 2: No Empty Lines in HTML Structure

CRITICAL: Do NOT add any empty lines within the HTML info card structure. Keep the entire HTML block continuous to prevent parsing errors.

Rule 3: Content Analysis Before Layout

REQUIRED: Analyze content along three dimensions before designing:

Density (determines breathing rhythm):

Density	Content Volume	Visual Treatment
Low	≤ 50 words core	"Big-character" composition. One oversized element dominates. Generous whitespace.
Medium	50–200 words	Hero + supporting panels. 2–3 main blocks with clear hierarchy.
High	200+ words	Asymmetric multi-column grids. Primary/secondary/supporting blocks. Never equal-weight tiles.

Structure (determines layout geometry):

Structure	Signal	Layout Pattern
Single point	One core concept	One anchor element dominates, rest recedes
Contrast	A vs B, old vs new	Split panel, two poles
Hierarchy	Layers build on each other	Stacked modules, pyramid
Flow	Sequential steps	Vertical cascade, numbered items
Radial	Core + derivatives	Hub with surrounding panels
Parallel	Multiple equal concepts	Asymmetric grid (never equal columns)

Mood (determines color temperature):

Mood	Visual Feel
Reflective	More whitespace, serif-heavy, lower contrast
Sharp	Strong contrast, bold type, vivid accent
Warm	Earth tones, rounded feel, gentle rhythm
Technical	Monospace accents, grid-like density

Rule 4: Tone Sensing

REQUIRED: Auto-select color palette based on content topic. Scan content keywords and match the closest tone:

Content Tone	Background	Accent	Trigger Keywords
Philosophical	#FAF8F4	#7C6853	cognition, thinking, meaning, philosophy, essence
Technical	#F5F7FA	#3D5A80	architecture, algorithm, system, API, code
Literary	#FBF9F1	#6B4E3D	story, narrative, writing, poetry, character
Scientific	#F4F8F6	#2D6A4F	experiment, data, research, paper, discovery
Business	#F4F3F0	#2D6A4F	market, strategy, growth, finance, investment
Creative	#F6F3F2	#B8432F	design, art, aesthetics, inspiration, creation
Default	#FAFAF8	#4A4A4A	When no clear match — prefer default over wrong match

When a style template is explicitly chosen, its colors take precedence over tone sensing. Use tone sensing as the default when no style is specified.

Rule 5: Title Protection

If the user provides a title explicitly, use it as-is for the main headline. Put editorial interpretation into subtitle, summary, or side modules. Do not silently rewrite the user's title.

Rule 6: Typography Hierarchy

Maintain a clear type scale and use it consistently:

• Hero title: 32px–48px, weight 700–900, tight letter-spacing (-0.02em)
• Subtitle / summary: 16px–20px, weight 400–500
• Body text: 14px–16px, weight 400, line-height 1.6–1.7
• Meta / tags / captions: 11px–13px, weight 500–700, uppercase with letter-spacing
• Body text color: never pure black — use #1a1a1a, #333, or #4a4a4a

Rule 7: Visual Weight Distribution

At least one module should feel visually heavier than the others. Avoid making every panel use the exact same treatment. Differentiate through scale, background tone, typographic weight, or accent rules.

Rule 8: Taste Rules (Anti-AI Checklist)

Before finalizing any card, check against these common AI-generated visual patterns:

Layout:

• No centered hero — Do not default-center titles. Prefer left-aligned or asymmetric
• No equal-width tiles — Three equal columns side by side is the #1 AI signature. Use 2fr 1fr, asymmetric grids, or staggered layouts
• No uniform panels — At least one panel must differ in scale, weight, or treatment

Typography:

• No pure black #000000 — Use off-black (#1a1a1a, #2d2a26) or warm/cool dark
• No oversized-only hierarchy — Build hierarchy with weight and color, not just font-size scaling

Color:

• Max 1 accent color, saturation < 80%
• No neon gradients — No purple-blue AI glow, no gradient-filled headlines
• Consistent temperature — Do not mix warm gray and cool gray in one card

Content:

• No filler data — Avoid 99.99%, 50%, 1234567. Use organic numbers (47.2%, 3.8M)
• No AI phrasing — Avoid "empower", "seamless", "unleash", "next-generation"

Spacing:

• Padding and margins must be mathematically precise, no awkward gaps
• Adjacent elements must be visually aligned

Style Examples

Partner Brief	layouts/partner-brief.md	Alliance updates, co-sell notes, partner summaries, channel reviews

Family Alignment Notes

• Prefer existing family primitives before inventing new class names. Current aligned layout families include card-doc-*, card-kpi-*, card-sequence-*, card-tile-*, card-map-*, card-compare-*, card-review-*, card-topic-*, and card-brief-*.
• When a new layout clearly belongs to one of those families, vary geometry and modifiers first. Do not create a parallel primitive vocabulary for the same role.
• Explicit special cases remain intentionally separate: quote-card, terminal-window, news-bulletin, and the strongest identity-driven style themes such as deep-night and glassmorphism.
• If a layout or style only shares mood and not structure, document the family relationship in prose rather than forcing additional primitive convergence.

Design Principles

Space and Breathing Room

• Card padding: 32px–48px from edges
• Module gaps: 16px–24px
• Title area must have generous line-height (1.1–1.3) and clear separation from body
• Never crowd content against card edges

Visual Accents

• Use 4px–6px thick rules as section dividers or accent borders
• Use subtle tinted backgrounds (rgba(0,0,0,0.03) or style-specific tints) for secondary panels
• Accent colors should be restrained: one highlight color used for rules, tags, or key numbers
• Optional: 4% noise overlay for paper texture (see style templates)

Content Rhythm

• High-density cards: group into overview → core judgment → supporting modules → conclusion
• Ranking content: asymmetric hero + structured list (avoid equal tiles)
• Tutorial/analysis content: overview → core insight → detail blocks → boundary/caveats → summary

Styling Reference

Common Classes (shared across all styles)

• .card-frame — outer container with max-width and padding

• .card-meta — meta line (category, date, version) in small uppercase
• .card-title — main headline
• .card-subtitle — secondary headline or summary
• .card-bar — thick accent rule divider
• .card-body — body text paragraph
• .card-body.dropcap — first paragraph with drop cap initial letter (editorial opening)
• .card-highlight — standalone short sentence (< 25 chars) with left accent border for key insights
• .card-grid — grid container; .card-grid-2 for two columns
• .card-panel — content panel with border-top accent
• .card-panel.heavy — heavier panel with more padding
• .card-panel.light — lighter panel with thinner border

• .card-divider — thin horizontal rule between sections
• .card-footer — bottom strip for source, attribution, or notes
• .card-endmark — end-of-content mark (∎) for editorial closure

Rich Text Elements

Drop cap (first paragraph only — creates editorial opening ceremony):

<p class="card-body dropcap">First paragraph text...</p>

Highlight quote (standalone insight, < 25 chars, with accent left border):

<p class="card-highlight">Key insight phrase</p>

Titled item (label + description pairs, for structured lists):

<div class="card-item">
  <p class="card-item-label">Item Title</p>
  <p class="card-panel-text">Item description text.</p>
</div>

Section divider:

<div class="card-divider"></div>

End mark (editorial closure, placed at content end):

<span class="card-endmark">∎</span>

Best Practices

Content Guidelines

1. Direct embedding only — Always embed HTML directly in Markdown, never use ```html code blocks
2. No empty lines in structure — Keep the entire HTML block continuous
3. Judge density first — Decide low/medium/high before picking layout
4. Protect user titles — Never silently rewrite a user-provided headline
5. Balance visual weight — At least one heavy block, one medium, one light
6. Use type scale consistently — Follow the size hierarchy defined above
7. Accent with restraint — One accent color, used sparingly for rules and highlights
8. Fill space intentionally — If a section looks empty, restructure hierarchy before adding filler content

Capability Upgrade

Mode Selection

• Quick: 把一段内容压缩成单张信息卡。
• Standard: 设计有层级、重点、数据和视觉节奏的信息卡。
• Deep: 根据受众、渠道、品牌语气和内容密度，生成系列化信息卡或汇报页组件。

Information Design Logic

先判断内容类型：概念解释、数据摘要、事件公告、风险提示、方法框架或项目状态。不同类型应使用不同层级，而不是套同一个版式。

Quality Gates

• 主标题能表达核心信息，而不是泛泛命名。
• 信息密度与卡片尺寸匹配。
• 关键数字、标签和结论有视觉优先级。
• HTML 可直接嵌入 Markdown，无代码围栏。
• 颜色、字体和留白不会压过内容。
