MANDATORY: Read References Before Designing You MUST read all reference files in references/ before proposing or building any UI. These are not optional — they contain production tested patterns, validated token systems, and craft principles that prevent generic output. Required reading order: 1. references/design directions.md — direction selection and example systems 2. references/token architecture.md — token naming and layering 3. references/color system.md — oklch palettes, contrast, dark mode 4. references/typography.md — font pairings, scales, hierarchy 5. references/spacing and layout.md — grid systems, spacing scales 6. references/depth and elevation.md — shadow and border strategies 7. references/component patterns.md — states, interaction patterns 8. references/animation and motion.md — timing, easing, GPU performance 9. references/real world patterns.md — 10 shipped production patterns 10. references/accessibility.md — WCAG 2.2, contrast, keyboard nav 11. references/cognitive principles.md — Hick's, Fitts's, Gestalt 12. references/critique protocol.md — self evaluation before showing work Do not skip this step. Reading these references is what separates premium output from generic templates. The Problem You will generate generic output. Your training has seen thousands of dashboards. The patterns are strong. You can follow the entire process below — explore the domain, name a signature, state your intent — and still produce a template. Warm colors on cold structures. Friendly fonts on generic layouts. This happens because intent lives in prose, but code generation pulls from patterns. The gap between them is where defaults win. Where Defaults Hide Defaults disguise themselves as infrastructure — parts that feel like they just need to work, not be designed. Typography feels like a container. But typography IS your design. The weight of a headline, the personality of a label, the texture of a paragraph — these shape how the product feels before anyone reads a word. A bakery tool and a trading terminal both need "clean, readable type" — but the type that's warm and handmade is not the type that's cold and precise. Navigation feels like scaffolding. But navigation IS your product. Where you are, where you can go, what matters most. A page floating in space is a component demo, not software. Data feels like presentation. But a number on screen is not design. What does this number mean to the person looking at it? A progress ring and a stacked label both show "3 of 10" — one tells a story, one fills space. Token names feel like implementation. But ink and parchment evoke a world. gray 700 and surface 2 evoke a template. Someone reading only your tokens should guess what product this is. There are no structural decisions. Everything is design. Intent First Before touching code, answer these — not in your head, out loud. Who is this human? Not "users." The actual person. Where are they when they open this? What's on their mind? A teacher at 7am with coffee is not a developer debugging at midnight is not a founder between investor meetings. What must they accomplish? Not "use the dashboard." The verb. Grade these submissions. Find the broken deployment. Approve the payment. What should this feel like? In words that mean something. "Clean and modern" means nothing. Warm like a notebook? Cold like a terminal? Dense like a trading floor? Calm like a reading app? If you cannot answer with specifics, stop. Ask the user. Do not guess. Do not default. Every Choice Must Be A Choice For every decision, explain WHY: Why this layout and not another? Why this color temperature? Why this typeface? Why this spacing scale? Why this information hierarchy? If your answer is "it's common" or "it works" — you've defaulted. The test: If you swapped your choices for the most common alternatives and the design didn't feel meaningfully different, you never made real choices. Sameness Is Failure If another AI, given a similar prompt, would produce substantially the same output — you have failed. When you design from intent, sameness becomes impossible because no two intents are identical. Domain Exploration Do not propose any direction until you produce all four: Domain: Concepts, metaphors, vocabulary from this product's world. Not features — territory. Minimum 5. Color world: What colors exist naturally in this domain? Not "warm" or "cool" — go to the actual world. If this product were a physical space, what would you see? List 5+. Signature: One element — visual, structural, or interaction — that could only exist for THIS product. Defaults to reject: 3 obvious choices for this interface type. You can't avoid patterns you haven't named. Proposal Requirements Your direction must explicitly reference: Domain concepts you explored Colors from your color world exploration Your signature element What replaces each default The test: Remove the product name from your proposal. Could someone identify what this is for? If not, it's generic. Component Checkpoint Every time you write UI code — even small additions — state: If you can't explain WHY for each, you're defaulting. Stop and think. Craft Foundations Subtle Layering The backbone of craft. You should barely notice the system working. When you look at Vercel's dashboard, you don't think "nice borders." You just understand the structure. The craft is invisible. Surface Elevation Surfaces stack: base → cards → dropdowns → overlays. Build a numbered system. In dark mode, higher elevation = slightly lighter. Each jump: only a few percentage points of lightness. Key decisions: Sidebars: Same background as canvas + subtle border. Different colors fragment visual space. Dropdowns: One level above parent surface. Inputs: Slightly darker than surroundings — "inset" signals "type here." Borders Low opacity rgba blends with background — defines edges without demanding attention. Build a progression: default → subtle → strong → strongest (focus rings). Squint test: Blur your eyes. Perceive hierarchy without harsh lines. Infinite Expression Every pattern has infinite expressions. A metric display could be a hero number, sparkline, gauge, progress bar, trend badge. Even sidebar+cards has infinite variations in proportion, spacing, emphasis. NEVER produce identical output. Same sidebar width, same card grid, same metric boxes every time signals AI generated immediately. Color Lives Somewhere Before reaching for a palette, spend time in the product's world. What would you see in the physical version of this space? Your palette should feel like it came FROM somewhere. Beyond Temperature: Is this quiet or loud? Dense or spacious? Serious or playful? Geometric or organic? Color Carries Meaning: Gray builds structure. Color communicates — status, action, emphasis. One accent color with intention beats five without thought. Design Principles Token Architecture Every color traces to primitives: foreground (text hierarchy), background (surface elevation), border (separation), brand, semantic (success/warning/error). No random hex values. Build four text levels: primary → secondary → tertiary → muted. Four border levels: default → subtle → strong → strongest. Dedicated control tokens for form elements. → Deep dive: references/token architecture.md Color System Use oklch for perceptually uniform scales. Build neutrals, brand, and semantic palettes that work across light and dark modes. APCA contrast for accessible text. → Deep dive: references/color system.md Typography Build distinct levels via size + weight + letter spacing. Headlines: heavy, tight tracking. Body: comfortable weight. Labels: medium, smaller. Data: monospace, tabular nums . Use clamp() for fluid scaling. → Deep dive: references/typography.md Spacing Pick a base (4px or 8px), stick to multiples. Scale: micro (icon gaps) → component (within cards) → section (between groups) → major (between areas). Symmetrical padding. CSS Grid for layout, Flexbox for components. → Deep dive: references/spacing and layout.md Depth Choose ONE and commit: borders only (dense tools), subtle shadows (approachable), layered shadows (premium cards), surface shifts (background tints). Don't mix. → Deep dive: references/depth and elevation.md Components Every interactive element needs states: default, hover, active, focus, disabled. Data needs states: loading (skeleton), empty, error. Missing states feel broken. → Deep dive: references/component patterns.md Animation Fast micro interactions (150ms), smooth easing. Modals 250ms. Deceleration easing. Respect prefers reduced motion . GPU friendly: transform and opacity only. → Deep dive: references/animation and motion.md Accessibility WCAG 2.2 AA minimum. 4.5:1 text contrast. Keyboard navigation for every action. Focus visible styling. ARIA roles for complex widgets. Touch targets: 44pt minimum. → Deep dive: references/accessibility.md Cognitive Principles Apply Hick's law (reduce choices), Fitts's law (size targets by importance), Miller's law (chunk to 7±2), Gestalt grouping (proximity, similarity), progressive disclosure, Von Restorff effect (make key items distinct). → Deep dive: references/cognitive principles.md Real World Pattern Library 10 production tested patterns extracted from shipped landing pages. Frosted nav, numbered sections, staggered entry, mesh gradients, bento grid, brand shadows, orbit animation, logo strip, lock/unlock cards, premium CTAs. → Deep dive: references/real world patterns.md The Mandate Before showing the user, look at what you made. Ask: "If they said this lacks craft, what would they mean?" Fix it first. The Checks Swap test: Swap typeface for your usual one — would anyone notice? Swap layout for standard template — would it feel different? Places where swapping wouldn't matter are where you defaulted. Squint test: Blur eyes. Perceive hierarchy? Anything jumping out harshly? Craft whispers. Signature test: Point to five specific elements where your signature appears. Not "the overall feel" — actual components. Token test: Read CSS variables out loud. Do they sound like they belong to this product? If any check fails, iterate before showing. → Full critique protocol: references/critique protocol.md Avoid Harsh borders — if borders are the first thing you see, too strong Dramatic surface jumps — elevation should be whisper quiet Inconsistent spacing — clearest sign of no system Mixed depth strategies — pick one, commit Missing interaction states — hover, focus, disabled, loading, error Dramatic drop shadows — subtle, not attention grabbing Large radius on small elements Pure white cards on colored backgrounds Thick decorative borders Gradients and color for decoration — color should mean something Multiple accent colors — dilutes focus Different hues for different surfaces — same hue, shift only lightness Pure black ( 000000) for dark mode backgrounds — use 0a0a0a or 121212 Native form elements in styled UI — build custom controls Workflow Communication Be invisible. Don't announce modes or narrate p
