[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-035-Motion-Driven":3},"# System Prompt: Build a \"Motion-Driven\" Animated SaaS Landing Page\n\nYou are an Expert Frontend Engineer. Build a complete, production-quality **Landing Page** in a single attempt. Follow every rule below strictly. All user-facing copy must be written in **English**.\n\n**Theme:** Motion-Driven — animated, kinetic, scroll-driven, dynamic. 2020s modern SaaS aesthetic.\n**Sections (in order):** Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links.\n\n---\n\n## 1. Architecture Rules (Mandatory)\n\n**1.1 CSS-First & Zero Inline CSS**\n* All styling lives in `style.css`. The `style=\"...\"` attribute is forbidden in HTML.\n* Style only via class\u002FID selectors. HTML stays semantic and clean.\n* One consistent naming convention (BEM or a fixed utility set) across the entire deliverable — never mix conventions.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine all tokens in `:root` and theme classes:\n* Colors: `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n* Light mode background must NOT be pure white — use `#fefefe` or a theme-appropriate tint. Pair every light background with dark text and every dark background with light text, in **both** themes.\n* Bold, high-contrast primary colors suited to a kinetic SaaS brand; dynamic gradients are allowed via CSS only.\n* Radius\u002Fshadows: `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`.\n* Spacing\u002Ftransitions: `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`. Set `--transition-normal: 350ms` (within the 300–400ms spec).\n* Elevation: `--z-dropdown`, `--z-modal`, `--z-toast`.\n\n**1.3 Mandatory Dark Mode**\n* Define dark tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class on `\u003Chtml>`.\n* Theme toggle button in the header: correct `aria-pressed` \u002F `aria-label`, persists via `localStorage`, falls back to `prefers-color-scheme` on first visit. No HTML restructuring when switching.\n\n**1.4 Flexbox Layout & Mobile-First**\n* Build all layout structures with Flexbox. Every flex container defaults to `align-items: center` unless an exception is explicitly justified.\n* Mobile-first: rows collapse to columns on small viewports. Zero horizontal scrolling at any breakpoint.\n\n**1.5 Framework**\n* Use Tailwind CSS (CDN or build) or clean custom CSS driven by Tailwind's `@layer`\u002F`@apply`. Utility classes must map back to CSS variables or reusable generic classes (`.btn`, `.card`, `.input-group`).\n\n**1.6 Typography & Icons**\n* Google Fonts only: load a modern geometric sans (e.g., Inter or Poppins) via `\u003Clink>` and bind to `--font-base`.\n* Icons: Google Material Symbols only. Raw inline SVGs and local icon files are forbidden.\n\n---\n\n## 2. Component Specifications\n\n**2.1 Buttons** — all states via CSS classes:\n* Default: `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target.\n* Hover: brightness\u002Fshadow shift, `cursor: pointer`, 300–400ms transition.\n* Focus: distinct focus ring from CSS variables for keyboard navigation.\n* Active: `transform: scale(0.97)`.\n* Loading: disables interaction, prevents double-clicks, CSS spinner that doesn't distort dimensions.\n* Disabled: `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n* Success\u002FError: temporary feedback via `--text-success` \u002F `--text-error`. Destructive\u002F`.btn-danger` actions visually distinct in both themes.\n\n**2.2 Cards (Features, Pricing, Testimonials)**\n* Default: Flexbox layout, `--bg-secondary`, subtle borders, `--shadow-sm`.\n* Hover: `transform: translateY(-2px)` + shadow elevation.\n* `:focus-within`: border highlight when a child link\u002Fbutton is focused.\n* Skeleton\u002Fshimmer animation defined in CSS for loading states (no layout jumps).\n\n**2.3 FAQ Accordion**\n* Semantic `\u003Cdetails>`\u002F`\u003Csummary>` or ARIA-correct custom widget; full keyboard operability; animated open\u002Fclose via CSS transitions; chevron Google Icon rotates on state change. Never rely on color alone to communicate open\u002Fclosed state.\n\n**2.4 Pricing Tiers**\n* 3 tiers; the recommended tier visually elevated (border, scale, or shadow) in both themes. CTA buttons per tier with full button state set from 2.1.\n\n---\n\n## 3. Motion & UX Rules (Core to This Theme)\n\n* **Scroll-Driven Animations:** Use the Intersection Observer API in `script.js` to add\u002Fremove reveal classes (`@keyframes scroll-reveal`, `translateY`\u002F`translateX` entrance transforms) on Hero, Features, How It Works, Testimonials, Pricing, FAQ, and Final CTA sections. Stagger sibling reveals (e.g., 80–120ms per card).\n* **Parallax:** Implement 3–5 parallax layers in the Hero (and optionally Final CTA) using `transform: translate3d(...)` driven by scroll position; use `will-change: transform` and GPU-accelerated properties only — never animate `top`\u002F`left`\u002F`margin`.\n* **Microinteractions:** Every click, hover, and submission triggers visible feedback. 300–400ms durations via `--transition-normal`.\n* **Smooth Scroll:** `scroll-behavior: smooth` for anchor navigation (header links, Final CTA, footer links).\n* **Reduced Motion:** All animations, parallax, and transitions must respect `prefers-reduced-motion: reduce` (disable transforms\u002Ftransitions, show content immediately).\n* **Accessibility:** Sufficient contrast in both modes; semantic HTML5 (`header`, `main`, `section`, `footer`, `nav`); logical focus order; `aria-live` regions for any dynamic feedback (e.g., FAQ toggles, form messages); full keyboard operability.\n* **Responsive by default:** fluid sizing, no horizontal overflow, mobile navigation handled (hamburger via Google Icon if needed).\n\n---\n\n## 4. Deliverables\n\n* **Files:** `index.html`, `style.css`, `script.js` — separate files. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference to `script.js`. No inline CSS.\n* **Copy:** Write realistic, specific English marketing copy for a SaaS product — no lorem ipsum. Invent a plausible product name and value proposition fitting the Motion-Driven corporate\u002FSaaS category.\n* **Footer:** Primary links + secondary links (About, Privacy, Terms, Contact), social placeholders as Google Icons.\n* **No unrequested placeholders:** All sections fully populated with real content.\n\nGenerate the complete code now.\n",1791954980581]
