小耳 Art Studio — Design Methodology Skill

Not a CSS copy. A methodology. Read references/DESIGN_PRINCIPLES.md first — the rest of this skill operationalizes those 8 principles.

v2.0 adds the interaction layer (the half of the site that lives in app.js, not styles.css) — physics garden, per-character text spring, tangential rotor, idle-spin. Without this layer, a reproduction looks like the site but doesn't feel like it.

What This Skill Reproduces

A trilingual (JA/EN/ZH) artist-portfolio aesthetic that reads like a Muji-meets-Hayao-Miyazaki zine, alive to the visitor's cursor:

Visual layer (Principles 1–7)

• Tender whitespace, not clinical minimalism
• Dual typography: DM Serif Display (editorial) × Caveat (handwritten) × system-ui (body)
• Pastel section palette (薄荷/奶油/樱粉/天青) with ONE high-saturation lime accent #c8ff00
• Hand-drawn SVG vocabulary: floral blobs, botanical vines, wavy underlines, dotted-line dividers
• Poetic micro-copy with onomatopoeia (uki uki / doki doki) and single-kanji product names
• Idle motion: 4–7s float / sway / rotate on decorations; hero text slide-in

Interaction layer (Principle 8)

• Physics garden — decorative SVGs are Matter.js rigid bodies with gravity; the cursor can grab and throw them
• Text spring (pencil) — bio paragraphs split into per-character spans, repelled by a custom pencil cursor
• Text spring (plain) — news titles split into chars, repelled by raw cursor proximity
• Tangential rotor — small spinnable marks (sakura nav button) transfer cursor tangent as angular velocity
• Idle-spin — ornament plus-marks rotate slowly always, accelerate 6× on hover
• Nav ↔ physics coupling (optional) — opening the nav panel pushes the physics world's right wall left, compressing the decorations

When to Use (trigger conditions)

Invoke this skill when the user's request matches any of:

• "做一个艺术家作品集 / 独立品牌站 / 日系风格网站"
• "按小耳 Art Studio 的调性做一个 …"
• "做一个手作品牌 / 衍生品商店 / 策展人主页"
• "日系 / 手帐 / 生活杂志风的着陆页"
• Explicit reference to this captured site, xiaoer-art.com, xiaoerai.xyz, xiaoercamera.xyz

If none of these match → don't invoke.

How to Use (for any model, in any agent)

Step 0 — Orient (every invocation)

Read in this exact order:

1. references/DESIGN_PRINCIPLES.md — the "why" (now 8 principles, includes interaction)
2. references/TOKENS.json — the "what" in machine-readable form
3. Whichever of TYPOGRAPHY.md / COLOR_SYSTEM.md / LAYOUT_RHYTHM.md / SVG_VOCABULARY.md / MOTION.md / COPYWRITING.md / INTERACTION.md / PHYSICS_GARDEN.md / TEXT_SPRING.md are relevant to the subtask

Step 1 — Classify the task

Step 2 — Generate

Follow the references. Do not invent colors/fonts outside the token system unless explicitly remixing (and then document what you swapped).

Step 3 — Verify (required before claiming done)

Run the Fidelity Checklist in references/DESIGN_PRINCIPLES.md#fidelity-checklist. If the output fails ≥2 checks, regenerate.

Cross-Agent Portability Notes

This skill uses only plain text formats:

• Markdown (.md) — any model can read
• JSON (.json) — any model can parse
• Inline SVG (in MD) — any model can emit
• Plain JS (.js) — pasteable, no build tooling (Matter.js loaded from CDN)

No Claude-Code-specific features in the content. The SKILL.md YAML frontmatter follows the Anthropic Skills spec but is also trivially ignorable by other frameworks. To port:

• Hermes: drop the folder into your skills directory, reference by name
• openclaw: same — the YAML name + description are the invocation trigger
• OpenAI / Gemini / Qwen / DeepSeek: prepend the SKILL.md body to your system prompt; load references on demand
• Raw CLI / no framework: cat SKILL.md references/DESIGN_PRINCIPLES.md and hand it to any LLM

Extension Points (what you're invited to change)

See references/REMIX_GUIDE.md for the full list, but the short version:

• Palette swap: keep the 1+4+1 structure (1 cream base + 4 pastel rotations + 1 lime accent), change the hues
• Font duo swap: keep the serif+handwritten pairing; swap DM Serif → Playfair / Lora, Caveat → Indie Flower / Caveat Brush
• SVG vocabulary theme: swap florals → marine creatures / kitchen herbs / mid-century shapes
• Language mix: JA/EN/ZH is not mandatory — any three-language split works if you keep the bilingual-column layout

What NOT To Change (brand-safe core)

• The three-role type system (editorial serif / handwritten cursive / body sans). Dropping to 2 collapses the charm.
• The dotted-line + wavy-line section dividers. Swapping these for <hr> kills the handcrafted feel.
• The 1 lime accent in a sea of pastels rule. Adding a second saturated color breaks the tension.
• The bilingual parallel column in the brand-intro section. Stripping translations makes it feel like generic e-commerce.
• The two cursor contracts (drag for decorations, opacity for controls). Mixing them — e.g., scaling product cards on hover — instantly looks like a SaaS site.
• At least one physics garden + one text-spring section. A reproduction with zero interaction layers looks like the site but doesn't feel like it. See references/DESIGN_PRINCIPLES.md § Principle 8.
