Build a complete, production-ready **Corporate & SaaS Landing Page** with a **Motion-Driven** theme (animated, kinetic, scroll-driven, dynamic) on the first attempt. Follow every rule below strictly.\n\n---\n\n## 1. Architecture & Strict Rules\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n* Keep **all** styling in a dedicated `style.css` file. **No `style=\"...\"` attributes anywhere in the HTML.**\n* Target all design properties, layouts, and states via **class or ID selectors only**.\n* HTML must remain clean, semantic, and style-agnostic — changing the site's look must require editing only the CSS file, never the markup.\n\n### 1.2 CSS Variables & Theme Tokens\nStore all visual tokens in `:root` (and theme classes):\n\n* **Colors:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n* **Motion-Driven Palette:** Use bold, high-contrast accent colors and **dynamic gradients** (e.g., animated gradient on hero text\u002Fbuttons) as the primary visual device. Success `#22C55E`, error `#EF4444`.\n* **Contrast Pairing:** Every light background token pairs with a dark text token and vice versa — enforced for **both** themes.\n* **Light Mode Background:** Do **not** default to pure white; pick a mood-fitting light background. Use `#fefefe` where near-white is needed.\n* **Radius\u002FShadows:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`.\n* **Spacing\u002FMotion:** `--spacing-gap`, `--transition-fast`, `--transition-normal` (set to **300–400ms**), `--ease-standard`.\n* **Stacking:** `--z-dropdown`, `--z-modal`, `--z-toast`.\n\n### 1.3 Mandatory Dark Mode\n* Define dark mode tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class selector.\n* Theme switching must work purely via CSS variables — no HTML restructuring.\n* Persist user choice in `localStorage`, falling back to `prefers-color-scheme` on first visit. Include a visible theme toggle with correct `aria-pressed` \u002F `aria-label` state.\n\n### 1.4 Flexbox Layout & Mobile-First\n* Build all layout structures with Flexbox (`display: flex`).\n* **Every flex container defaults to `align-items: center`** unless an explicit exception is justified in a CSS comment.\n* Mobile-first: rows convert to columns on small viewports. **No horizontal scrolling at any breakpoint.**\n\n### 1.5 Framework\n* Use Tailwind CSS (or clean custom CSS via `@layer` \u002F `@apply`). All utilities must map back to CSS variables or reusable classes (`.btn`, `.card`, `.input-group`).\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n* Text: Google Fonts (e.g., Inter or Poppins) via `\u003Clink>`\u002F`@import`, bound to `--font-base`.\n* Icons: **Google Material Symbols\u002FIcons only.** No raw inline SVGs, no local icon files.\n\n---\n\n## 2. Sections to Build\n\nBuild these sections in order, all with entrance animations and scroll-driven reveals:\n\n1. **Hero** — full-viewport, animated gradient headline, CTA buttons, **parallax background with 3–5 layers** (e.g., floating gradient orbs\u002Fshapes moving at different speeds on scroll).\n2. **Features** — 3 interactive cards.\n3. **How It Works** — 3 numbered steps with staggered scroll-reveal animations.\n4. **Testimonials** — at least 2 quotes with avatar (icon-based), reveal on scroll.\n5. **Pricing** — 3 tiers (Basic \u002F Pro highlighted \u002F Enterprise), each with a CTA button.\n6. **FAQ** — accordion (details\u002Fsummary or ARIA-compliant custom), animated open\u002Fclose.\n7. **Final CTA** — bold gradient panel with primary button.\n8. **Footer** — secondary links, social icons (Google Icons), copyright.\n\n### Component State Requirements\n* **Buttons:** default (flex, `align-items: center`, `justify-content: center`, `gap: 0.5rem`, min 44×44px), hover (brightness\u002Fshadow shift, `cursor: pointer`), focus (distinct focus ring via CSS variables), active (`transform: scale(0.97)`), loading (disabled interactions, CSS spinner, no dimension distortion), disabled (`opacity: 0.5`, greyscale, `cursor: not-allowed`), success\u002Ferror feedback via `--text-success` \u002F `--text-error`.\n* **Cards:** default (`--bg-secondary`, subtle border, elevation), hover (`translateY(-2px)` + shadow shift), `:focus-within` border highlight, **skeleton shimmer** loading state, empty state (Google Icon + guidance text).\n* **FAQ\u002FInputs:** empty, focused (outline ring), filled, valid, invalid (error border + red text + error icon), disabled, read-only. Flex container wrapping label, field, and dedicated error container.\n\n---\n\n## 3. Motion & UX Rules (Core of This Theme)\n\n* **Scroll Animations:** Use the **Intersection Observer API** to add reveal classes (e.g., `.is-visible`) triggering `@keyframes scroll-reveal` with `translateY`\u002F`translateX` transforms.\n* **Parallax:** 3–5 hero layers moving at different rates on scroll — implemented via `transform: translate3d()` only (GPU-accelerated), never `top`\u002F`margin`.\n* **Transitions:** All state changes use `transition: var(--transition-normal)` (300–400ms) with `--ease-standard`.\n* **Performance:** Use `transform` \u002F `opacity` for all animations; apply `will-change: transform` on animated layers; `scroll-behavior: smooth` for anchor navigation.\n* **Reduced Motion:** Respect `prefers-reduced-motion: reduce` — disable parallax and heavy animations, keep instant state changes.\n* **Accessibility:** Sufficient contrast in both themes; never rely on color alone for state; semantic HTML5; correct ARIA roles\u002Flabels (accordion, toggle); logical focus order; full keyboard operability; `aria-live` regions for dynamic feedback.\n* **Mandatory Visual Feedback:** Every click, hover, and submission triggers a visible state change.\n* **Destructive\u002Fdanger actions:** visually distinct via `.btn-danger` in both themes.\n\n---\n\n## 4. Deliverables & Output Format\n\n* **Files:** Separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference. No inline CSS.\n* **Naming:** One consistent convention (BEM or a fixed utility set) throughout — never mix.\n* **Copy:** All user-facing copy in **English**, written as realistic corporate SaaS content (real product name, real feature descriptions, real pricing). No lorem ipsum.\n* **Exception Clause:** If any mandatory rule above conflicts with a user requirement, keep the mandatory rule and note the exception explicitly in a code comment rather than silently dropping it.\n\nGenerate the complete code now.\n",1791954980034]
