Your task is to code a complete, production-quality Landing Page on the first attempt. Every rule in this specification is mandatory. Where your habits conflict with a rule, the rule wins.\n\n**Mission:** Build a single-page marketing site in the **\"Degraded Colorful \u002F Vibrant Gradient\"** style — an energetic, modern, infographic-flavored landing page featuring rainbow-spectrum gradients, gradient text fills, glossy finishes, animated color flows, and color-coded sections — with full Light and Dark mode support.\n\n---\n\n## 0. DESIGN BRIEF\n\n**0.1 Style Definition**\n- **Name:** Degraded Colorful \u002F Vibrant Gradient\n- **Type:** Infographic\n- **Era:** Modern Vibrant\n- **Modes:** Full Light ✓ \u002F Full Dark ✓ (both mandatory)\n- **Keywords:** color gradient transitions, vibrant hues, dynamic color flows, modern aesthetics, rainbow spectrum, glossy finishes, energetic, contemporary\n\n**0.2 Color Palette**\n- **Primary:** White `#FFFFFF` (surfaces\u002Fgloss only — see exception clause in 1.2), Dark Text `#222222`, multi-gradient rainbow accent\n- **Spectrum accents:** Red `#FF0000`, Orange `#FF7F00`, Yellow `#FFFF00`, Green `#00FF00`, Blue `#0000FF`, Indigo `#4B0082`, Violet `#9400D3`\n\n**0.3 Visual Effects (all must be implemented)**\n- High-key bright lighting (airy, luminous hero in light mode; glowing gradients in dark mode)\n- Gradient flow animations (animated `background-position`)\n- Color bleeding (soft, blurred radial-gradient blobs)\n- Vibrant highlight transitions on hover\u002Ffocus\n- Smooth gradient morphing\n- Energetic reveals (scroll-triggered entrance animations)\n\n**0.4 Visual Direction**\nMulti-color gradient transitions, rainbow spectrum effects, dynamic color flows, glossy finishes, gradient text fills (display headings only), color-coded sections, modern energetic aesthetic, smooth gradient backgrounds.\n\n**0.5 Required CSS Techniques**\n- Multi-stop `linear-gradient(135deg, ...)` backgrounds\n- `background-clip: text` + `-webkit-background-clip: text` + `color: transparent` for gradient text\n- Animated gradient flow via oversized backgrounds (`background-size: 200% 200%` or larger) and:\n```css\n@keyframes gradient-shift {\n  0%   { background-position: 0% 50%; }\n  50%  { background-position: 100% 50%; }\n  100% { background-position: 0% 50%; }\n}\n```\n- `filter: saturate(1.2)` on gradient surfaces and imagery\n- Glossy overlay sheen via translucent white `linear-gradient` layer\n- Color-coded sections via per-section accent variables (see 5.x)\n\n**0.6 Content Direction**\nInvent a fitting fictional product\u002Fbrand (e.g., a gradient\u002Fcolor design platform such as \"ChromaFlow\" or \"Prism\") and author realistic, energetic, contemporary **English** marketing copy for every section. No lorem ipsum anywhere.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n- All styling lives in `style.css`. The `style=\"...\"` attribute is **forbidden** anywhere in the HTML.\n- All design properties, layout rules, and states are targeted via **class or ID selectors only**.\n- HTML remains clean, semantic, and style-agnostic — re-theming the site must require editing `style.css` only, never the markup.\n\n**1.2 CSS Variables & Theme Tokens**\nStore every visual token in `:root`, overridden per theme:\n\n- **Base tokens (light mode):** `--primary` (Violet `#9400D3` as lead brand accent), `--secondary` (Indigo `#4B0082`), `--bg-primary: #fefefe`, `--bg-secondary` (very light tint, e.g., `#F6F4FB`), `--text-primary: #222222`, `--text-secondary` (e.g., `#55555E`), `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n- **Spectrum tokens (decorative only):** `--spectrum-red: #FF0000`, `--spectrum-orange: #FF7F00`, `--spectrum-yellow: #FFFF00`, `--spectrum-green: #00FF00`, `--spectrum-blue: #0000FF`, `--spectrum-indigo: #4B0082`, `--spectrum-violet: #9400D3`.\n- **Text-safe spectrum variants:** Pure hues such as Yellow `#FFFF00` and Green `#00FF00` fail contrast on light backgrounds. Define darkened text-safe variants for light mode (e.g., `--spectrum-yellow-text: #8A6D00`, `--spectrum-green-text: #047857`, `--spectrum-orange-text: #B45309`) and brightened variants for dark mode (e.g., `--spectrum-yellow-text: #FFE066`, `--spectrum-blue-text: #748FFC`). Any text, meaningful icon, or focus ring uses text-safe variants; pure hues are reserved for decorative gradients, borders, glows, and background layers.\n- **Gradient tokens:** `--gradient-rainbow`, `--gradient-features` (Blue→Indigo), `--gradient-steps` (Green→Blue), `--gradient-testimonials` (Orange→Red), `--gradient-pricing` (Indigo→Violet), `--gradient-faq` (Yellow→Orange), `--gradient-cta` (rainbow), `--gloss-overlay` (translucent white sheen).\n- **Shape, elevation, motion tokens:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`, `--shadow-glow` (colored soft glow), `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`, `--z-dropdown`, `--z-modal`, `--z-toast`.\n- **Contrast pairing:** Every light background token pairs with dark text tokens and every dark background token pairs with light text tokens — enforced in **both** themes. The light-mode page background must be `#fefefe`, never `#ffffff`.\n- **Exception clause:** The source palette designates White `#FFFFFF` as primary — `#FFFFFF` is permitted for card surfaces, glossy sheen layers, and button fills paired with `#222222` text, but the light-mode `--bg-primary` token must remain `#fefefe`.\n- **Gradient text rule:** Gradient text fills apply **only** to large display type (H1 and section headings ≥ 2rem). Select gradient stop ranges that maintain ≥ 3:1 contrast against the section background (favor red→violet ranges on light backgrounds; brighter ranges on dark). Body copy always uses solid `--text-primary`.\n\n**1.3 Mandatory Dark Mode Support**\n- Define dark tokens under **both** `@media (prefers-color-scheme: dark)` **and** a `.dark` class on `\u003Chtml>`.\n- Dark theme: deep near-black background (e.g., `#0C0C14`), light text (e.g., `#F4F4F8`), gradients glowing against the dark canvas.\n- Theme toggle in the header: Google Material Symbols icon, correct `aria-pressed` and `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\"), persisted via `localStorage`, falling back to `prefers-color-scheme` on first visit.\n- Switching themes must require **zero HTML restructuring** — only CSS variable overrides.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with **Flexbox**.\n- Every flex container **defaults to `align-items: center`** unless an exception is explicitly justified in a CSS comment.\n- Mobile-first: rows collapse to columns on small viewports; **zero horizontal scrolling** at any width from 320px up.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS (or clean custom CSS driven by `@layer` \u002F `@apply`). All utilities must map back to CSS variables or generic reusable classes (`.btn`, `.card`, `.input-group`, `.section`, `.nav`, `.footer`).\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- **Text:** Google Fonts — a display face (Sora or Poppins) bound to `--font-display` for headings, and Inter bound to `--font-base` for body. Include via `\u003Clink>` or `@import`.\n- **Icons:** Google Material Symbols exclusively. Raw inline SVGs and local icon files are **forbidden**.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component** (`.btn` base + variants: `.btn--primary` gradient, `.btn--secondary` outline, `.btn--ghost`)\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px.\n- **Hover:** brightness\u002Fshadow shift with `cursor: pointer`.\n- **Focus:** distinct focus ring via CSS variables (`outline` \u002F `box-shadow`) for keyboard navigation.\n- **Active\u002FPressed:** `transform: scale(0.97)` feedback.\n- **Loading:** disables interaction, prevents double-clicks, renders a CSS spinner or animated Google Icon without distorting button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback styles driven by `--text-success` \u002F `--text-error`.\n- **Gradient buttons:** the label must hold ≥ 4.5:1 contrast at **every point** of the gradient — achieve this via stop-range selection (e.g., red→violet with white text) or a scrim overlay layer.\n\n**2.2 Card Component** (`.card` + modifiers)\n- **Default:** flexible Flexbox layout, `--bg-secondary`, subtle border, elevation via variables, glossy sheen overlay, color-coded gradient accent (top border or icon badge) per section.\n- **Hover:** elevation\u002Fshadow shift plus `transform: translateY(-2px)`.\n- **Focus-within:** card border highlights when a child link\u002Fbutton receives focus.\n- **Loading (Skeleton):** shimmer animation defined in CSS, no layout jumps.\n- **Empty State:** structured fallback with a Google Icon and clear guidance text.\n\n**2.3 Form & Input Requirements** (`.input-group` — used for the Final CTA email capture)\n- **States:** Empty, Focused (outline ring), Filled, Valid (success border\u002Ficon), Invalid (error border, red text, error icon), Disabled, Read-only.\n- **Structure:** flex container wrapping a label, input field, and a dedicated error feedback container.\n- Errors announced via `aria-live`.\n\n**2.4 Modal \u002F Popup Requirements** (only if one is implemented, e.g., a \"Choose Plan\" confirmation)\n- **States:** Opening, Open, Loading, Success\u002FError, Closing — all animated via CSS transitions.\n- **UX:** centered flex container (`align-items: center`), backdrop overlay, Google Icon close button, keyboard focus trapping, close via `Esc` or overlay click.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing and breakpoints with no horizontal overflow.\n- **Smooth animations:** `transition: var(--transition-normal)` on all state changes; `gradient-shift` runs continuously on hero and CTA backgrounds.\n- **`prefers-reduced-motion`:** disable gradient-shift and morphing, make reveals instant, disable smooth scrolling.\n- **Accessibility (a11y):** AA contrast in both Light and Dark modes; never rely on color alone to communicate state; semantic HTML5 (`header`, `nav`, `main`, `section`, `footer`); correct ARIA roles\u002Flabels on all custom widgets (FAQ accordion, mobile menu, theme toggle, pricing toggle if present); logical DOM\u002Ffocus order; full keyboard operability; `aria-live` regions for dynamic feedback (form errors, toasts, loading states).\n- **Mandatory visual feedback:** every click, hover, or submission triggers a visible state change.\n- **Destructive actions** (if any appear): visually distinct in both themes.\n- **Performance:** animate only `transform`, `opacity`, and `background-position`; apply `saturate(1.2)` statically, never animated on large surfaces.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File structure:** separate `index.html`, `style.css`, and `script.js`. No inline styles. No inline `\u003Cscript>` blocks beyond a single deferred entry point: `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`.\n- **Naming convention:** BEM exclusively (e.g., `.hero__title`, `.pricing-card__feature-list`). If Tailwind is used, it is compiled **behind** BEM class names via `@apply` — the HTML carries only BEM class names. Never mix conventions.\n- **No unrequested placeholders:** content was left unspecified, so author real English marketing copy for every section — lorem ipsum is prohibited.\n- All user-facing copy, class names, variable names, and file names in English\u002FASCII.\n\n---\n\n## 5. PAGE BLUEPRINT — SECTION-BY-SECTION REQUIREMENTS\n\n**Global:** sticky header; skip-to-content link; smooth anchor scrolling with `scroll-padding-top` for the header; scroll-triggered reveal animations via `IntersectionObserver` toggling a class (CSS performs the motion). Implement color-coding architecturally, e.g. `.section--features { --section-gradient: var(--gradient-features); --section-accent: var(--spectrum-blue-text); }`.\n\n**5.1 Header \u002F Nav** — gradient-text logo, anchor links to all sections, theme toggle (per 1.3), primary CTA. Mobile: hamburger button with `aria-expanded` \u002F `aria-controls`, closes on `Esc` and link click, focus managed, layered at `--z-dropdown`.\n\n**5.2 Hero** — full rainbow animated gradient background (`gradient-shift` keyframes, oversized `background-size`), soft color-bleed blobs, high-key bright lighting; H1 with gradient text fill; subheadline; dual CTAs (primary gradient + secondary outline); optional infographic stats strip (big numbers + Material icons). Energetic staggered entrance reveals.\n\n**5.3 Features (3 cards)** — color-coded **Blue→Indigo**. Each card: gradient icon badge (Material symbol), title, description. All card states per 2.2.\n\n**5.4 How It Works (3 steps)** — color-coded **Green→Blue**, infographic style: numbered gradient step markers, a connecting gradient line built in pure CSS, icon + title + text per step; stacks vertically on mobile.\n\n**5.5 Testimonials** — color-coded **Orange→Red**. Three cards: quote, five-star Material icon rating with accessible label (\"Rated 5 out of 5 stars\"), gradient-circle avatar with initials, name and role.\n\n**5.6 Pricing (3 tiers)** — color-coded **Indigo→Violet**. Middle tier highlighted as \"Most Popular\" with gradient border\u002Fglow and elevated styling. Each tier: name, price, feature list with Material check icons, CTA button. Optional monthly\u002Fyearly toggle — if present, it must be a keyboard-operable switch with `aria-checked` and a clearly visible state.\n\n**5.7 FAQ** — color-coded **Yellow→Orange**. Five to six accordion items: question as a `\u003Cbutton>` with `aria-expanded` + `aria-controls`, rotating `expand_more` Material icon, animated panel (CSS `grid-template-rows` or equivalent), fully keyboard operable.\n\n**5.8 Final CTA** — full-spectrum gradient panel with gloss overlay; headline, supporting copy, email capture form (`.input-group` per 2.3) whose submit button transitions through loading → success\u002Ferror feedback announced via `aria-live`.\n\n**5.9 Footer** — dark surface with light text in light mode (contrast-paired); subtle animated spectrum top border; secondary link groups (Product, Company, Resources); social icons (Material symbols with `aria-label`s); copyright with dynamic year; small gradient-text brand mark.\n",1791954989714]
