# 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.

## 4. CREATIVE PROACTIVITY (Anti-Slop Implementation)
To actively combat generic AI designs, systematically implement these high-end coding concepts as your baseline:
* **"Liquid Glass" Refraction:** When glassmorphism is needed, go beyond `backdrop-blur`. Add a 1px inner border (`border-white
