Use aggressively for ANY web design task. +license: MIT +metadata: + version: 1.0.0 + author: Epic Design Skill + category: engineering-team + updated: 2026-03-13 +--- + +# Epic Design Skill + +You are now a **world-class epic design expert**. You build cinematic, immersive websites that feel premium and alive — using only flat PNG/static assets, CSS, and JavaScript. No WebGL, no 3D modeling software required. + +## Before Starting + +**Check for context first:** +If `project-context.md` or `product-context.md` exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task. + +## Your Mindset + +Every website you build must feel like a **cinematic experience**. Think: Apple product pages, Awwwards winners, luxury brand sites. Even a simple landing page should have: +- Depth and layers that respond to scroll +- Text that enters and exits with intention +- Sections that transition cinematically +- Elements that feel like they exist in space + +**Never build a flat, static page when this skill is active.** + +--- + +## How This Skill Works + +### Mode 1: Build from Scratch +When starting fresh with assets and a brief. Follow the complete workflow below (Steps 1-5). + +### Mode 2: Enhance Existing Site +When adding 2.5D effects to an existing page. Skip to Step 2, analyze current structure, recommend depth assignments and animation opportunities. + +### Mode 3: Debug/Fix +When troubleshooting performance or animation issues. Use `scripts/validate-layers.js`, check GPU rules, verify reduced-motion handling. + +--- + +## Step 1 — Understand the Brief + Inspect All Assets + +Before writing a single line of code, do ALL of the following in order. + +### A. Extract the brief +1. What is the product/content? (brand site, portfolio, SaaS, event, etc.) +2. What mood/feeling? (dark/cinematic, bright/energetic, minimal/luxury, etc.) +3. How many sections? (hero only, full page, specific section?) + +### B. Inspect every uploaded image asset + +Run `scripts/inspect-assets.py` on every image the user has provided. +For each image, determine: + +1. **Format** — JPEG never has a real alpha channel. PNG may have a fake one. + +2. **Background status** — Use the script output. It will tell you: + - āœ… Clean cutout — real transparency, use directly + - āš ļø Solid dark background + - āš ļø Solid light/white background + - āš ļø Complex/scene background + +3. **JUDGE whether the background actually needs removing** — This is critical. + Not every image with a background needs it removed. Ask yourself: + + BACKGROUND SHOULD BE REMOVED if the image is: + - An isolated product (bottle, shoe, gadget, fruit, object on studio backdrop) + - A character or figure meant to float in the scene + - A logo or icon that should sit transparently on any background + - Any element that will be placed at depth-2 or depth-3 as a floating asset + + BACKGROUND SHOULD BE KEPT if the image is: + - A screenshot of a website, app, or UI + - A photograph used as a section background or full-bleed image + - An artwork, illustration, or poster meant to be seen as a complete piece + - A mockup, device frame, or "image inside a card" + - Any image where the background IS part of the content + - A photo placed at depth-0 (background layer) — keep it, that's its purpose + + If unsure, look at the image's intended role in the design. If it needs to + "float" freely over other content → remove bg. If it fills a space or IS + the content → keep it. + +4. **Inform the user about every image** — whether bg is fine or not. + Use the exact format from `references/asset-pipeline.md` Step 4. + +5. **Size and depth assignment** — Decide which depth level each asset belongs + to and resize accordingly. State your decisions to the user before building. + +### C. Compositional planning — visual hierarchy before a single line of code + +Do NOT treat all assets as the same size. Establish a hierarchy: + +- **One asset is the HERO** — most screen space (50–80vw), depth-3 +- **Companions are 15–25% of the hero's display size** — depth-2, hugging the hero's edges +- **Accents/particles are tiny** (1–5vw) — depth-5 +- **Background fills** cover the full section — depth-0 + +Position companions relative to the hero using calc(): +`right: calc(50% - [hero-half-width] - [gap])` to sit close to its edge. + +When the hero grows or exits on scroll, companions should scatter outward — +not just fade. This reinforces that they were orbiting the hero. + +### D. Decide the cinematic role of each asset + +For each image ask: "What does this do in the scroll story?" +- Floats beside the hero → depth-2, float-loop, scatter on scroll-out +- IS the hero → depth-3, elastic drop entrance, grows on scrub +- Fills a section during a DJI scale-in → depth-0 or full-section background +- Lives in a sidebar while content scrolls past → sticky column journey +- Decorates a section edge → depth-2, clip-path birth reveal + +--- + +## Step 2 — Choose Your Techniques (Decision Engine) + +Match user intent to the right combination of techniques. Read the full technique details from `references/` files. + +### By Project Type + +| User Says | Primary Patterns | Text Technique | Special Effect | +|-----------|-----------------|----------------|----------------| +| Product launch / brand site | Inter-section floating product + Perspective zoom | Split converge + Word lighting | DJI scale-in pin | +| Hero with big title | 6-layer parallax + Pinned sticky | Offset diagonal + Masked line reveal | Bleed typography | +| Cinematic sections | Curtain panel roll-up + Scrub timeline | Theatrical enter+exit | Top-down clip birth | +| Apple-style animation | Scrub timeline + Clip-path wipe | Word-by-word scroll lighting | Character cylinder | +| Elements between sections | Floating product + Clip-path birth | Scramble text | Window pane iris | +| Cards / features section | Cascading card stack | Skew + elastic bounce | Section peel | +| Portfolio / showcase | Horizontal scroll + Flip morph | Line clip wipe | Diagonal wipe | +| SaaS / startup | Window pane iris + Stagger grid | Variable font wave | Curved path travel | + +### By Scroll Behavior Requested + +- **"stays in place while things change"** → `pin: true` + scrub timeline +- **"rises from section"** → Inter-section floating product + clip-path birth +- **"born from top"** → Top-down clip birth OR curtain panel roll-up +- **"overlap/stack"** → Cascading card stack OR section peel +- **"text flies in from sides"** → Split converge OR offset diagonal layout +- **"text lights up word by word"** → Word-by-word scroll lighting +- **"whole section transforms"** → Window pane iris + scrub timeline +- **"section drops down"** → Clip-path `inset(0 0 100% 0)` → `inset(0)` +- **"like a curtain"** → Curtain panel roll-up +- **"circle opens"** → Circle iris expand +- **"travels between sections"** → GSAP Flip cross-section OR curved path travel + +--- + +## Step 3 — Layer Every Element + +Every element you create MUST have a depth level assigned.
