[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-604-Dark-Glassmorphism-Infographic":3},"# SYSTEM PROMPT — BUILD SPEC: \"DARK GLASSMORPHISM INFOGRAPHIC\" LANDING PAGE\n\n**Role & Objective:** Act as a Senior Frontend Engineer and Expert UI Designer. Your task is to code a complete, production-quality Landing Page on the first attempt — no TODOs, no truncated code, no second-pass placeholders. Theme: **Dark Glassmorphism Infographic** (Type: Infographic · Era: 2020s Glassmorphism · Mood: premium, modern UI).\n\n---\n\n## 0. PROJECT BRIEF & PAGE BLUEPRINT\n\n**0.1 Theme Identity & Keywords**\nGlassmorphic containers, frosted glass effects, semi-transparent panels, dark ambient, neon accent lighting, layered glass depth, premium, modern UI. Visual direction: frosted glass containers (`backdrop-filter: blur`) floating over a dark ambient background (#1A1A2E), lit by neon cyan\u002Fpurple accent lighting, with layered glass depth and glow effects.\n\n**0.2 Color Palette → Token Mapping**\n- Primary: Dark Navy `#1A1A2E` (base background), White Text `#FFFFFF`, Cyan `#00D4FF`, Lavender `#E0AAFF`\n- Secondary: Pink `#FFB6FF`, Rose `#FF6B9D`, Purple `#9D4EDD`, Deep Purple `#3A0CA3`, plus glow effects (neon box-shadows\u002Ftext-shadows derived from these hues)\n\n**0.3 Mandatory Glass Baseline (exact values)**\nEvery glass surface must use, via CSS variables: `backdrop-filter: blur(20px) saturate(150%)` (with `-webkit-` prefix), `background: rgba(255,255,255,0.08)`, `border: 1px solid rgba(255,255,255,0.15)`, `box-shadow: 0 8px 32px rgba(0,0,0,0.3)`, `color: #FFFFFF`, and neon `text-shadow` on accent headlines only.\n\n**0.4 Signature Visual Effects (implement as reusable CSS keyframes\u002Fclasses)**\nNeon accent lighting, dark ambient background, glass panel fade-in, blur depth animations, glow pulse on hover, layered reveal transitions (staggered).\n\n**0.5 Required Sections (in this order)**\n1. **Global chrome:** Sticky glass navbar (frosted, semi-transparent) with logo, anchor links to every section, primary CTA; collapses into a glass hamburger menu on mobile (panel at `--z-dropdown`, keyboard operable, `aria-expanded`, closes on `Esc`). Fixed dark ambient background layer built purely in CSS: base `#1A1A2E` + layered radial gradients (cyan, purple, deep purple, lavender at low alpha) + 2–3 large blurred glow orbs drifting slowly. This layer MUST sit behind all glass panels so `backdrop-filter` has rich content to frost.\n2. **Hero:** Full-viewport glass composition — display headline with neon gradient text (cyan→lavender) and subtle neon text-shadow, subcopy, dual CTAs (primary neon-gradient button + secondary glass-outline button), and a layered glass \"infographic\" visual (stacked translucent stat panels with Material Symbols icons) entering with staggered layered-reveal. Include 2–3 glass stat chips with real metrics.\n3. **Features (3 cards):** Grid of three glass cards, each with a Material Symbols icon inside a neon-glowing glass badge, title, description; hover = glow pulse + `translateY(-2px)`; staggered fade-in on scroll.\n4. **How It Works (3 steps):** Three numbered glass step panels (01\u002F02\u002F03) connected by a glowing gradient connector line (CSS pseudo-element), each with icon + short copy; layered reveal on scroll.\n5. **Testimonials:** Three glass quote cards, each with a CSS-drawn avatar (glass circle with initials — no external images), quote, name, role, decorative quote Material icon.\n6. **Pricing (3 tiers):** Three glass pricing panels; the middle tier is the featured tier (`.glass-card--featured`) with a neon gradient border, elevated glow\u002Fscale, and a \"Most Popular\" badge; each tier lists name, price, feature list with Material check icons, and a CTA button.\n7. **FAQ:** Accessible accordion of 4–6 glass panels — each trigger is a `\u003Cbutton>` with `aria-expanded` + `aria-controls` (native `\u003Cdetails>\u002F\u003Csummary>` is an acceptable alternative), animated expansion, rotating chevron Material icon, fully keyboard operable.\n8. **Final CTA:** Large glass panel with glow pulse, headline, and an email-capture form (glass input + button) implementing every state in §2.3, with inline success\u002Ferror feedback in an `aria-live` region.\n9. **Footer:** Glass-bordered footer with brand, secondary link columns (Product \u002F Company \u002F Support), social icons (Material Symbols), copyright, and a \"back to top\" control.\n\n**0.6 Copy:** Write realistic, on-brand English marketing copy for a plausible premium tech product (invent a product name and value proposition). Lorem ipsum is forbidden.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n* **No Inline CSS:** The `style=\"...\"` attribute is forbidden anywhere in the HTML, as are `\u003Cstyle>` blocks in the markup.\n* **Class\u002FID Selectors Only:** All design properties, layout rules, and states must be targeted via class or ID selectors in `style.css`.\n* **Minimal HTML Modifications:** HTML must remain clean, semantic, and agnostic of visual styling — restyling the site requires editing only `style.css`, never the markup.\n\n**1.2 CSS Variables (`var(--...)`) & Theme Tokens**\nStore every visual token in `:root`:\n* **Colors:** `--primary: #00D4FF` (Cyan), `--secondary: #E0AAFF` (Lavender), `--bg-primary: #1A1A2E`, `--bg-secondary: #232344` (elevated navy for solid surfaces), `--text-primary: #FFFFFF`, `--text-secondary: rgba(255,255,255,0.72)`, `--text-success: #4ADE80`, `--text-error: #FF6B9D` (Rose), `--border-default: rgba(255,255,255,0.15)`, `--border-error: rgba(255,107,157,0.65)`, `--border-success: rgba(74,222,128,0.65)`.\n* **Accent\u002FGlow Tokens:** `--accent-pink: #FFB6FF`, `--accent-rose: #FF6B9D`, `--accent-purple: #9D4EDD`, `--accent-deep-purple: #3A0CA3`, `--glow-cyan`, `--glow-purple` (low-alpha neon shadows), `--neon-text-shadow`.\n* **Glass Tokens (mandatory baseline, §0.3):** `--glass-bg: rgba(255,255,255,0.08)`, `--glass-border: rgba(255,255,255,0.15)`, `--glass-shadow: 0 8px 32px rgba(0,0,0,0.3)`, `--glass-blur: blur(20px) saturate(150%)`.\n* **Contrast Pairing:** Every dark\u002Fglass background token pairs with `--text-primary`\u002F`--text-secondary` (light text); never place white text on light surfaces. Never use `#ffffff` as a background — the theme background is `#1A1A2E`; near-white appears only as low-alpha glass tints.\n* **Radius & Shadows:** `--radius-sm: 8px`, `--radius-md: 16px`, `--radius-lg: 24px`, `--shadow-sm`, `--shadow-md`.\n* **Spacing & Transitions:** `--spacing-gap`, `--transition-fast: 150ms`, `--transition-normal: 300ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`.\n* **Elevation\u002FStacking:** `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300` — layered components must never conflict.\n\n**1.3 Mandatory Dark Mode Support**\nDark Mode must always be defined:\n* **Implementation:** Provide the dark color tokens under `@media (prefers-color-scheme: dark)` and\u002For a `.dark` class selector, in addition to the `:root` defaults.\n* **Theme Switching:** Background and text variables must switch seamlessly with zero HTML restructuring.\n* **Persistence:** Any user theme choice must persist via `localStorage`, falling back to `prefers-color-scheme` on first visit; a visible toggle, if present, must expose correct `aria-pressed`\u002F`aria-label` state.\n* **Exception (dark-only theme):** The source spec mandates \"Light: ✗ No \u002F Dark: ✓ Full\" — this landing page is dark-only, so the dark glassmorphism palette is the single default theme (declared in `:root` and mirrored in `.dark` and the `prefers-color-scheme: dark` block so the dark aesthetic renders identically under any OS setting); do NOT invent a light palette, and omit the visible light\u002Fdark toggle.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n* **Default Alignment Rule:** Every flex container defaults to `align-items: center` (`items-center`) unless an exception is explicitly justified in a CSS comment (e.g., step connectors using `stretch`).\n* **Mobile-Friendly First:** All flex layouts must be responsive out of the box — nav → hamburger, all card\u002Fstep\u002Fpricing\u002Ftestimonial rows → single column, hero text stacks above visual. No horizontal scrolling at any viewport from 320px upward.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n* Use Tailwind CSS for layout\u002Fspacing utilities; all visual identity (glass, neon, components) must live in `style.css` as reusable component classes (`.glass-panel`, `.btn`, `.card`, `.input-group`, `.faq-item`) bound to the CSS variables above.\n* Utility classes and arbitrary values must reference `var(--...)` tokens — never hardcode hex values in class names or markup.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n* **Text:** Load Google Fonts via `\u003Clink>` — a premium geometric display face for headings (e.g., \"Sora\" or \"Space Grotesk\") and \"Inter\" for body — bound to `--font-display` and `--font-base`; apply fluid sizing with `clamp()`.\n* **Icons:** Use Google Material Symbols (Rounded variant) exclusively. Raw inline SVGs, local icon files, emoji-as-icons, and third-party icon libraries are forbidden.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component Requirements**\nStyle all states via CSS classes (`.btn`, `.btn--primary`, `.btn--glass`, `.btn--danger`):\n* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` with a minimum 44×44px touch target. `.btn--primary` = neon gradient (cyan→purple) with glow shadow; `.btn--glass` = frosted glass with 1px glass border.\n* **Hover:** Glow pulse — neon box-shadow intensifies with slight brightness lift; `cursor: pointer`; `transition: var(--transition-normal)`.\n* **Focus:** Distinct focus ring via `outline`\u002F`box-shadow` using `--primary` (e.g., 2px cyan ring with offset), clearly visible on glass backgrounds; never remove focus outlines.\n* **Active\u002FPressed:** `transform: scale(0.97)`.\n* **Loading:** `.is-loading` disables pointer events, prevents double-clicks, and renders a CSS spinner or animated Material icon in place of the label without changing button dimensions.\n* **Disabled:** `opacity: 0.5`, greyscale filter, `cursor: not-allowed`.\n* **Success\u002FError:** Temporary feedback classes driven by `--text-success` \u002F `--text-error`, announced via an `aria-live` region.\n* **Destructive:** `.btn-danger` must be visually distinct in the dark theme (rose-tinted glass\u002Fborder + icon + label — never color alone).\n\n**2.2 Card Component Requirements** (`.glass-card`)\n* **Default:** Flexible flexbox layout with `--glass-bg`, `--glass-blur` (with `-webkit-backdrop-filter`), 1px `--glass-border`, `--glass-shadow`, `--radius-lg`, consistent internal padding.\n* **Hover:** Elevation\u002Fglow shift plus `transform: translateY(-2px)` and a glow pulse (low-alpha cyan\u002Fpurple neon shadow).\n* **Focus-within:** Card border brightens (e.g., toward `rgba(255,255,255,0.35)` or a cyan tint) when any child link\u002Fbutton receives focus.\n* **Loading (Skeleton):** Glass-tinted shimmer animation on placeholder blocks with fixed heights to prevent layout jumps.\n* **Empty State:** Structured fallback layout with a Material Symbols icon and clear guidance text.\n\n**2.3 Form & Input Requirements** (`.input-group`)\n* **Structure:** Flex container wrapping a `\u003Clabel>`, the input field, and a dedicated error-feedback container (`aria-live`, linked via `aria-describedby`).\n* **States (all class-driven):** Empty; Focused (cyan outline ring via `box-shadow`); Filled; Valid (`--border-success` + Material check icon + `--text-success` message); Invalid (`--border-error`, `--text-error` message + Material error icon, announced via `aria-live`); Disabled (`opacity` + `cursor: not-allowed`); Read-only.\n* Apply to the Final CTA email capture (and any other input); validate email format in `script.js`; never rely on color alone — pair borders with icons and text messages.\n\n**2.4 Modal \u002F Popup Requirements**\nGoverns any overlay you introduce (e.g., a plan-details or confirmation dialog; the mobile menu follows dropdown rules instead):\n* **States:** Opening, Open, Loading, Success\u002FError, Closing — all animated via CSS transitions (glass panel scale\u002Fblur-in, backdrop fade).\n* **UX Features:** Centered flex container (`align-items: center; justify-content: center`), blurred dark backdrop overlay (`rgba(0,0,0,0.6)` + `backdrop-filter`), close button with a Material Symbols icon and `aria-label=\"Close\"`, keyboard focus trap, close via `Esc` and overlay click, focus returns to the trigger on close, `role=\"dialog\"` + `aria-modal=\"true\"`.\n* **Stacking:** Backdrop\u002Fmodal at `--z-modal`; any toast feedback at `--z-toast`.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n* **Responsive by Default:** Fluid `clamp()` typography, standard breakpoints, zero horizontal overflow from 320px upward; all grids stack to a single column on mobile.\n* **Smooth Animations:** `transition: var(--transition-normal)` on all state changes. Implement the theme's signature effects as reusable keyframes: glass panel fade-in, layered reveal transitions (staggered via `transition-delay` or a custom-property index), blur depth animations (subtle `blur → 0` + `translateY` on reveal), glow pulse on hover. Scroll reveals use `IntersectionObserver` toggling an `.is-visible` class as progressive enhancement — all content must be visible with JS disabled.\n* **Reduced Motion:** Under `prefers-reduced-motion: reduce`, disable orb drift, pulses, shimmer, and reveal transforms; keep instant opacity changes only.\n* **Accessibility (a11y):** WCAG AA contrast in the dark theme — body text is `#FFFFFF` or `rgba(255,255,255,0.72)+` on glass over `#1A1A2E`. Neon text-shadow and glow are decorative only, never the sole state indicator. Use semantic HTML5 (`header`, `nav`, `main`, `section` with `aria-labelledby`, `footer`), a skip-to-content link, smooth scrolling with `scroll-padding-top` for the sticky header, logical DOM\u002Ffocus order, full keyboard operability (menu, accordion, modal, forms), and `aria-live` regions for dynamic feedback (form errors, submit success, loading).\n* **Mandatory Visual Feedback:** Every click, hover, and submission triggers a visible state change (hover glow, pressed scale, submit → loading → success\u002Ferror).\n* **Destructive Actions:** Any delete\u002Fdanger control uses `.btn-danger` — distinct in the dark theme via rose border\u002Fglow plus icon and label.\n* **Glass Technical Enforcement:** Every `backdrop-filter` usage includes the `-webkit-backdrop-filter` prefix; glass panels must always have the ambient gradient\u002Forb layer behind them so the frost effect is visible.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n* **File Structure:** Three separate files — `index.html`, `style.css`, `script.js`. `index.html` links `style.css` and references exactly one deferred entry point (`\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`). No inline `\u003Cscript>` blocks, no inline styles, no `\u003Cstyle>` tags in the HTML.\n* **Naming Convention:** One consistent convention across the entire deliverable — BEM (e.g., `.glass-card`, `.glass-card__title`, `.glass-card--featured`, `.btn--primary`). Never mix conventions; Tailwind utilities are permitted only for layout\u002Fspacing and must not duplicate BEM component responsibilities.\n* **No Unrequested Placeholders:** All eight sections fully built and wired (nav anchors, mobile menu, accordion, form validation, reveal animations) with realistic English copy per §0.6. Lorem ipsum and empty stub sections are prohibited.\n* **Assets:** No external assets beyond Google Fonts and Google Material Symbols; avatars and all decorative visuals are CSS-drawn (initials, gradients, glow orbs) — no raster images required.\n* **First Attempt:** Deliver the complete, final code immediately in one pass.\n",1791954989872]
