Build a complete, production-quality landing page on the first attempt — no drafts, no partial output. The result must be responsive, accessible, glass-morphed, and fully theme-switchable, matching the design brief below exactly.\n\n---\n\n## 0. THEME BRIEF & CREATIVE DIRECTION\n\n- **Theme Name:** GLYPH RAIN — composed cascade\n- **Type:** Cyberpunk · **Era:** 2020s Contemporary · **Keywords:** glyph, rain, matrix, glass, translucent, blur\n- **Concept:** A fictional product landing page built around the image of neon-green glyph rain — a matrix-like cascade of falling characters — streaming behind frosted-glass panels. Author a plausible fictional product consistent with this concept (e.g., *\"GlyphRain — a real-time generative typography engine that turns live data streams into composed cascades of type\"*). You have creative authority over the product name and copy, but all copy must be original, realistic, professional, and written in English.\n- **Palette tokens:** Primary `#7dffb0` (neon green), Secondary `#fff`, deep surfaces `#0a0f0c` and `#040705`.\n- **Light\u002FDark:** The style spec marks **Light mode as primary (✓)** and Dark as supported (○). Implement **both modes fully**; the cyberpunk mood must remain convincing in each.\n- **Required visual effects:** Glassmorphism (`backdrop-filter` blur + translucent surfaces), hover effects, CSS filters, transitions, transforms, box shadows, text shadows (neon glow), border radius. Technical toolkit: Flexbox, Backdrop Filter, CSS Filters, Transitions.\n\n---\n\n## 1. PAGE SECTIONS & CONTENT REQUIREMENTS\n\nBuild the sections in this order. All section copy is authored by you — realistic, English, theme-consistent. No lorem ipsum anywhere.\n\n**1.1 Glass Header & Navigation**\n- Fixed header with strong glass effect (blur + translucency) over the page; contains a text logo, anchor links to each section, a **theme toggle button** (§2.3), and a compact CTA scrolling to Pricing.\n- On viewports where links no longer fit: collapse to a Material Symbols hamburger button that toggles a glass dropdown drawer (`--z-dropdown`), with `aria-expanded`\u002F`aria-controls`, Esc-to-close, and focus moved into the drawer.\n- Apply `scroll-margin-top` to all anchored sections so the fixed header never covers content.\n\n**1.2 Hero — Glyph Rain**\n- Full-viewport hero with an animated **glyph rain background**: repeated monospace glyph characters (katakana, digits, code symbols) falling in staggered vertical columns, animated purely with CSS keyframes (`translateY` only), colored as low-opacity neon green, faded at top\u002Fbottom via a linear-gradient mask. The rain container is decorative: `aria-hidden=\"true\"`.\n- Foreground: a frosted-glass panel (eyebrow badge, glowing H1, subheadline, two CTAs — a primary button and a glass\u002Fghost button) plus a small stats row and a scroll-cue icon. Headline gets a neon text-shadow glow in dark mode; the glow is restrained in light mode.\n- Rain must be CSS-driven (text content, not SVG), GPU-friendly (`transform`-only animations), and fully disabled under `prefers-reduced-motion`.\n\n**1.3 Features — 3 Glass Cards**\n- Three glass cards, each with a Material Symbols icon, title, and description. Cards demonstrate the full card state spec (§3.2), including a hover lift with a green glow-shadow shift.\n\n**1.4 How It Works — 3 Steps**\n- Three numbered steps (01\u002F02\u002F03) in a flex row that stacks to a column on mobile, each with a Material Symbols icon, a numbered glass badge, and copy. Connect the steps with a CSS-drawn vertical\u002Fhorizontal guide line.\n\n**1.5 Testimonials**\n- Three quote cards with monogram avatars (styled initials in a glass circle — no external images), fictional names, and roles.\n- **Exercise the card loading and empty states here:** on first load, render shimmer skeleton cards with `aria-busy=\"true\"` for ~600ms, then transition to real content. Also define and render the CSS empty-state pattern (Material Symbol icon + guidance text) if the testimonial data set is empty.\n\n**1.6 Pricing — 3 Tiers**\n- Three tiers (theme the names, e.g., Signal \u002F Cascade \u002F Deluge) in glass cards; the middle tier is visually elevated and carries a \"Most popular\" badge.\n- Each tier CTA opens the plan-selection modal (§3.4). The featured tier CTA uses the primary button style; others use ghost\u002Fglass.\n\n**1.7 FAQ — Accessible Accordion**\n- 5–6 questions. Each item is a `\u003Cbutton>` with `aria-expanded`\u002F`aria-controls` toggling a panel; animate open\u002Fclose with CSS only (e.g., `grid-template-rows: 0fr → 1fr`) — never JS height measuring. Panels are keyboard operable and announce state changes.\n\n**1.8 Final CTA — Email Capture**\n- A large glass panel with a headline, supporting copy, and an email-capture form exercising the full form state spec (§3.3): inline validation, error messages in an `aria-live` region, a loading button state, success feedback, and a confirmation toast (§3.4).\n\n**1.9 Footer — Secondary Links**\n- Multi-column footer (Product \u002F Company \u002F Resources \u002F Legal) with secondary links, Material Symbols social icons, and a copyright line. Style must stay legible in both themes.\n\n---\n\n## 2. STRICT RULES & ARCHITECTURE\n\n**2.1 CSS-First Architecture & Zero Inline CSS**\n- **No inline CSS:** the `style=\"...\"` attribute is forbidden in HTML.\n- **Class\u002FID selectors only:** every design property, layout rule, and state is targeted via classes\u002FIDs in `style.css`.\n- **Minimal HTML coupling:** markup stays semantic and styling-agnostic — restyling the site must require editing CSS only.\n\n**2.2 CSS Variables & Theme Tokens**\n- Store all tokens in `:root`, overridden by the `.dark` theme class:\n  - **Colors:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n  - **Radius & shadows:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`.\n  - **Spacing & transitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.\n  - **Stacking:** `--z-dropdown`, `--z-modal`, `--z-toast`.\n  - **Theme extras:** `--font-display`, `--font-mono`, `--primary-strong`, `--glass-bg`, `--glass-border`, `--blur-strength`, `--glow`, `--rain-color`.\n- **Token mapping:** Light mode — `--bg-primary` is a mood-fitting tinted near-white (e.g., desaturated pale green such as `#e9f2ec`), **never pure white**; use `#fefefe` only where a near-white surface is required; text tokens are deep dark greens (`#0a0f0c` family). Dark mode — `--bg-primary: #040705`, `--bg-secondary: #0a0f0c`, text tokens are light.\n- **Contrast pairing (mandatory, both themes):** every light background token pairs with a dark text token; every dark background token pairs with a light text token. `#7dffb0` is a *light* color — when used as a fill, it must always carry dark text (`#040705`). Never use `#7dffb0` as text on light backgrounds; in light mode, interactive text\u002Flinks\u002Fborders use a darkened green variant `--primary-strong` (e.g., `#0c7a44`) to preserve WCAG AA.\n- All glass surfaces read from `--glass-bg` \u002F `--glass-border` \u002F `--blur-strength` so both themes stay consistent. Provide a solid-background fallback via `@supports not (backdrop-filter: …)`.\n\n**2.3 Mandatory Dark Mode**\n- **Implementation:** Dark tokens are defined under the `.dark` class selector applied to `\u003Chtml>`. *(Exception per style spec: because the spec marks Light (✓) as primary, first visit defaults to **Light** rather than `prefers-color-scheme`; the .dark-class approach covers all other requirements.)*\n- **Theme switching:** Background\u002Ftext\u002Fvariable swaps must occur with zero HTML restructuring; also set `color-scheme: light` \u002F `dark` so native controls follow the theme.\n- **Persistence:** Save the user's choice to `localStorage`; restore it on every visit. Provide a visible toggle in the header with correct `aria-pressed` state and descriptive `aria-label` (e.g., \"Toggle dark mode\"), swapping Material Symbols `light_mode`\u002F`dark_mode` icons via CSS. Theme changes must animate smoothly via `--transition-normal`.\n\n**2.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with **Flexbox**: containers default to `align-items: center` (`items-center`) unless a spec point explicitly justifies an exception (e.g., card body text).\n- Mobile-first: rows collapse to columns at defined breakpoints, fluid sizing, no horizontal overflow at any width (fix layout by design, not with `overflow-x: hidden` band-aids).\n\n**2.5 Framework — Tailwind CSS**\n- Use Tailwind CSS by default; define reusable component classes (`.btn`, `.card`, `.input-group`, etc.) via `@layer`\u002F`@apply` so every utility maps back to the CSS variables. Never hardcode hex values inside utilities.\n\n**2.6 Typography & Icons — Google Fonts Mandatory**\n- **Text:** load Google Fonts via `\u003Clink>` — a cyber display font (e.g., Chakra Petch or Space Grotesk) bound to `--font-display`, Inter bound to `--font-base`, and JetBrains Mono bound to `--font-mono` (glyph rain, code accents, step numerals).\n- **Icons:** Google Material Symbols only. **Raw inline SVGs and local icon files are forbidden.** The glyph-rain characters are text content, not icons, and are permitted.\n\n---\n\n## 3. COMPONENT DESIGN SPECIFICATIONS\n\n**3.1 Button Component**\nAll states styled via classes; base button is `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` with a 44×44px minimum touch target.\n- **Default:** primary variant = neon-green fill with dark text; ghost variant = glass surface with themed border.\n- **Hover:** brightness\u002Fshadow shift (green glow allowed), `cursor: pointer`.\n- **Focus:** distinct neon focus ring built from CSS variables (`outline` and\u002For `box-shadow`) — never remove it.\n- **Active:** `transform: scale(0.97)` press feedback.\n- **Loading:** disables interaction and double-clicks; renders a CSS spinner or animated Google icon **without changing button dimensions**.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** transient feedback styles driven by `--text-success` \u002F `--text-error`. `.btn-danger` must be visually distinct in both themes.\n\n**3.2 Card Component**\n- **Default:** flexible Flexbox layout styled with `--bg-secondary`\u002F`--glass-*` tokens, subtle border, and elevation via `--shadow-sm`.\n- **Hover:** `transform: translateY(-2px)` plus a shadow\u002Fglow shift.\n- **Focus-within:** border highlights when a child link\u002Fbutton receives focus.\n- **Loading (Skeleton):** shimmer animation defined purely in CSS to prevent layout jumps (exercised in Testimonials, §1.5).\n- **Empty State:** structured fallback layout with a Material Symbol icon and clear guidance text.\n\n**3.3 Form & Input Component**\n- **Structure:** flex container wrapping a `\u003Clabel>`, the input, and a dedicated error-feedback element (`aria-live=\"polite\"`).\n- **States (all class-driven):** empty, focused (neon outline ring), filled, valid (success border + Material check icon), invalid (error border, red text, error icon, message), disabled, and **read-only** (demonstrate via a locked \"Selected plan\" field in the modal).\n- Validate on blur\u002Fsubmit client-side; never rely on color alone — pair borders with icons and text.\n\n**3.4 Modal & Toast**\n- **Modal (plan selection, opened from Pricing CTAs):** covers all states — opening, open, loading, success\u002Ferror, closing — each animated via CSS transitions (opacity + scale; backdrop blur-in). Centered with `align-items: center`; semi-transparent backdrop; close button with a Material Symbol (\"close\"); full **focus trap** with focus returned to the trigger on close; closable via `Esc` and overlay click; layered at `--z-modal`. Contains a short form (§3.3) whose submit runs loading → success → auto-close.\n- **Toast:** fixed-position notification at `--z-toast`, `role=\"status\"`, auto-dismiss with a close button; used for newsletter\u002Fform feedback.\n\n---\n\n## 4. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid type\u002Fsizing, standard breakpoints, zero horizontal overflow.\n- **Smooth animations:** every state change transitions with `transition: var(--transition-normal)`; fully respect `prefers-reduced-motion` (glyph rain pauses, lifts\u002Fparallax\u002Ftransitions are disabled, reveal animations show content immediately).\n- **Accessibility:** AA contrast in both Light and Dark modes; never communicate state by color alone; semantic HTML5 throughout; correct ARIA roles\u002Flabels on the accordion, mobile drawer, modal, toggle, and toast; logical DOM\u002Ffocus order; complete keyboard operability — no mouse-only interactions; `aria-live` regions for all dynamic feedback.\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Micro-interactions:** `scroll-behavior: smooth` anchor navigation (disabled under reduced motion); subtle reveal-on-scroll via IntersectionObserver adding a single class, with CSS handling the transition; glass depth and glow respond to hover across cards, buttons, and the header.\n\n---\n\n## 5. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** separate `index.html`, `style.css`, and `script.js`. HTML references exactly one script — `\u003Cscript src=\"script.js\" defer>` — and no other inline `\u003Cscript>` blocks.\n- **Naming convention:** one consistent convention across the entire deliverable (BEM recommended: `block__element--modifier`); never mix conventions.\n- **Copy:** all user-facing copy in English, authored by you — realistic headlines, feature names, testimonials, tier descriptions, FAQ entries. No lorem ipsum, no \"TODO\" stubs. Placeholder `href=\"#\"` is permitted only for footer links with no real target.\n- **Greenfield build:** you author the markup freely — this is not an edit of existing code.\n- Deliver the finished site in one pass: complete HTML, complete CSS, complete JS.\n",1791954992472]
