High-Agency Frontend Skill

1. ACTIVE BASELINE CONFIGURATION

• DESIGN_VARIANCE: 8 (1=Perfect Symmetry, 10=Artsy Chaos)
• MOTION_INTENSITY: 6 (1=Static/No movement, 10=Cinematic/Magic Physics)
• VISUAL_DENSITY: 4 (1=Art Gallery/Airy, 10=Pilot Cockpit/Packed Data)

**AI Instruction:** The standard baseline for all generations is strictly set to these values (8, 6, 4). Do not ask the user to edit this file. Otherwise, ALWAYS listen to the user: adapt these values dynamically based on what they explicitly request in their chat prompts. Use these baseline (or user-overridden) values as your global variables to drive the specific logic in Sections 3 through 7.

2. DEFAULT ARCHITECTURE & CONVENTIONS

Unless the user explicitly specifies a different stack, adhere to these structural constraints to maintain consistency:

• **DEPENDENCY VERIFICATION [MANDATORY]:** Before importing ANY 3rd party library (e.g. `framer-motion`, `lucide-react`, `zustand`), you MUST check `package.json`. If the package is missing, you MUST output the installation command (e.g. `npm install package-name`) before providing the code. **Never** assume a library exists.
• **Framework & Interactivity:** React or Next.js. Default to Server Components (`RSC`).
• **RSC SAFETY:** Global state works ONLY in Client Components. In Next.js, wrap providers in a `"use client"` component.
• **INTERACTIVITY ISOLATION:** If Sections 4 or 7 (Motion/Liquid Glass) are active, the specific interactive UI component MUST be extracted as an isolated leaf component with `'use client'` at the very top. Server Components must exclusively render static layouts.
• **State Management:** Use local `useState`/`useReducer` for isolated UI. Use global state strictly for deep prop-drilling avoidance.
• **Styling Policy:** Use Tailwind CSS (v3/v4) for 90% of styling.
• **TAILWIND VERSION LOCK:** Check `package.json` first. Do not use v4 syntax in v3 projects.
• **T4 CONFIG GUARD:** For v4, do NOT use `tailwindcss` plugin in `postcss.config.js`. Use `@tailwindcss/postcss` or the Vite plugin.
• **ANTI-EMOJI POLICY [CRITICAL]:** NEVER use emojis in code, markup, text content, or alt text. Replace symbols with high-quality icons (Radix, Phosphor) or clean SVG primitives. Emojis are BANNED.
• **Responsiveness & Spacing:**
• Standardize breakpoints (`sm`, `md`, `lg`, `xl`).
• Contain page layouts using `max-w-[1400px] mx-auto` or `max-w-7xl`.
• **Viewport Stability [CRITICAL]:** NEVER use `h-screen` for full-height Hero sections. ALWAYS use `min-h-[100dvh]` to prevent catastrophic layout jumping on mobile browsers (iOS Safari).
• **Grid over Flex-Math:** NEVER use complex flexbox percentage math (`w-[calc(33%-1rem)]`). ALWAYS use CSS Grid (`grid grid-cols-1 md:grid-cols-3 gap-6`) for reliable structures.
• **Icons:** You MUST use exactly `@phosphor-icons/react` or `@radix-ui/react-icons` as the import paths (check installed version). Standardize `strokeWidth` globally (e.g., exclusively use `1.5` or `2.0`).

3. DESIGN ENGINEERING DIRECTIVES (Bias Correction)

LLMs have statistical biases toward specific UI cliché patterns. Proactively construct premium interfaces using these engineered rules:

**Rule 1: Deterministic Typography**

• **Display/Headlines:** Default to `text-4xl md:text-6xl tracking-tighter leading-none`.
• **ANTI-SLOP:** Discourage `Inter` for "Premium" or "Creative" vibes. Force unique character using `Geist`, `Outfit`, `Cabinet Grotesk`, or `Satoshi`.
• **TECHNICAL UI RULE:** Serif fonts are strictly BANNED for Dashboard/Software UIs. For these contexts, use exclusively high-end Sans-Serif pairings (`Geist` + `Geist Mono` or `Satoshi` + `JetBrains Mono`).
• **Body/Paragraphs:** Default to `text-base text-gray-600 leading-relaxed max-w-[65ch]`.

**Rule 2: Color Calibration**

• **Constraint:** Max 1 Accent Color. Saturation < 80%.
• **THE LILA BAN:** The "AI Purple/Blue" aesthetic is strictly BANNED. No purple button glows, no neon gradients. Use absolute neutral bases (Zinc/Slate) with high-contrast, singular accents (e.g. Emerald, Electric Blue, or Deep Rose).
• **COLOR CONSISTENCY:** Stick to one palette for the entire output. Do not fluctuate between warm and cool grays within the same project.

**Rule 3: Layout Diversification**

• **ANTI-CENTER BIAS:** Centered Hero/H1 sections are strictly BANNED when `LAYOUT_VARIANCE > 4`. Force "Split Screen" (50/50), "Left Aligned content/Right Aligned asset", or "Asymmetric White-space" structures.

**Rule 4: Materiality, Shadows, and "Anti-Card Overuse"**

• **DASHBOARD HARDENING:** For `VISUAL_DENSITY > 7`, generic card containers are strictly BANNED. Use logic-grouping via `border-t`, `divide-y`, or purely negative space. Data metrics should breathe without being boxed in unless elevation (z-index) is functionally required.
• **Execution:** Use cards ONLY when elevation communicates hierarchy. When a shadow is used, tint it to the background hue.

**Rule 5: Interactive UI States**

• **Mandatory Generation:** LLMs naturally generate "static" successful states. You MUST implement full interaction cycles:
• **Loading:** Skeletal loaders matching layout sizes (avoid generic circular spinners).
• **Empty States:** Beautifully composed empty states indicating how to populate data.
• **Error States:** Clear, inline error reporting (e.g., forms).
• **Tactile Feedback:** On `:active`, use `-translate-y-[1px]` or `scale-[0.98]` to simulate a physical push indicating success/action.

**Rule 6: Data & Form Patterns**

• **Forms:** Label MUST sit above input. Helper text is optional but should exist in markup. Error text below input. Use a standard `gap-2` for input blocks.
