Your task is to code a complete, production-quality landing page on the first attempt — full, final code in a single response, no TODOs, no partial output.\n\n## 0. PROJECT BRIEF\n\n**Theme:** Creative Voltage — Bold, Creative, Energetic, Retro-Modern (2024–2026 Creative Energy). **Output category:** Retro & Pop. **Mode:** Dark-only.\n\n**Brand & copy:** Invent one fictional creative brand (a design studio or creative toolkit) with a coherent name, tagline, and consistent, realistic copy. All user-facing copy must be written in English.\n\n**Visual direction:** Split panels (electric blue left \u002F dark navy right), CSS-only halftone textures, neon yellow badges and callouts, script-typography flourishes, bold 200ms transitions. Reuse the split-panel motif in section headers (blue chip + navy chip) for cohesion. Neon badge spec: `.neon-badge { background: #d4ff00; color: #1a1a2e; padding: 4px 12px; border-radius: 4px; font-weight: 700 }` (Space Mono 700, uppercase, letter-spaced).\n\n**Palette (bind to tokens):**\n- Electric Blue `#0066ff` — primary, left panels, primary buttons\n- Dark Navy `#1a1a2e` — page background, right panels\n- Neon Yellow `#d4ff00` — badges, callouts, featured pricing, accents\n- White `#ffffff` — text on blue\u002Fnavy only; never a page background (if a white surface is ever required, use `#fefefe`)\n- Dark Grey `#333333` — text on yellow surfaces only\n- Light Blue `#3388ff` — links\u002Faccents on navy\n\n**Fonts (Google Fonts only):** Syne 700\u002F800 (display), Space Mono 400\u002F700 (body, labels, numerals, code accents), Caveat 600\u002F700 (script flourishes).\n\n**Page sections (build in this order):**\n1. **Sticky header** — Syne 800 wordmark, anchor nav, `.btn--neon` CTA, mobile hamburger (`aria-expanded`, animated panel).\n2. **Hero** — split panel: left `.panel--blue` with `.halftone`; right `.panel--dark` with `.halftone--light`. Left: neon-badge eyebrow, Syne 800 uppercase headline (fluid `clamp()` size), Space Mono subcopy, `.btn--neon` + `.btn--ghost`. Right: CSS-only collage (rotated neon badges, halftone circle, mono \"sticker\" card, Caveat annotation with arrow icon). Panels stack on mobile.\n3. **Marquee divider** (decorative retro-pop strip) — repeating brand phrase, CSS keyframe scroll, duplicated content `aria-hidden=\"true\"`, pauses on hover, disabled under `prefers-reduced-motion`.\n4. **Features — 3 cards** (flex row that wraps) — Material Symbol in a neon chip, Syne 700 title, Space Mono body, hover lift + yellow glow.\n5. **How It Works — 3 steps** — 01\u002F02\u002F03 numerals in Space Mono 700, dashed CSS connector line, icon + title + short copy, stacks on mobile.\n6. **Testimonials — 3 quote cards** — oversized yellow quote glyph, quote, author + role, initials-avatar circle (no external assets; picsum placeholders permitted only if photos are preferred).\n7. **Pricing — 3 tiers** — middle tier featured on neon yellow (`#d4ff00` bg, `#1a1a2e` text, \"MOST POPULAR\" badge); monthly\u002Fyearly toggle button (`aria-pressed`, 200ms price swap, `aria-live` price region); per-tier CTA; check-icon feature lists.\n8. **FAQ — accessible accordion** — 5–6 items, `\u003Cbutton aria-expanded>` + region, plus\u002Fminus Material icon rotation, 200ms CSS height animation, fully keyboard operable.\n9. **Final CTA** — full-bleed `.panel--blue` with `.halftone`: huge Syne headline, Caveat accent line, email-capture form with submit showing loading → success\u002Ferror states.\n10. **Footer** — dark navy: brand block, secondary link columns (Product \u002F Company \u002F Resources), Material social icons, mono copyright line.\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 applied via class\u002FID selectors only.\n- HTML stays clean and semantic; changing the look must never require markup edits.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine in `:root`:\n- **Colors:** `--primary: #0066ff`; `--secondary: #d4ff00`; `--bg-primary: #1a1a2e`; `--bg-secondary: #232342` (lifted navy for cards); `--text-primary: #ffffff`; `--text-secondary: #b8b8d0`; `--text-success: #58e07d`; `--text-error: #ff6b6b`; `--border-default: rgba(255,255,255,0.16)`; `--border-error` \u002F `--border-success` in matching hues.\n- **Extra theme tokens:** `--accent-blue: #3388ff`; `--ink: #1a1a2e` (text on yellow); `--grey-dark: #333333` (yellow surfaces only); `--glow-yellow` \u002F `--glow-blue` neon box-shadows.\n- **Shape\u002Fdepth:** `--radius-sm: 4px`; `--radius-md: 8px`; `--radius-lg: 16px`; `--shadow-sm`; `--shadow-md`.\n- **Motion\u002Fspace:** `--spacing-gap` (with a defined scale); `--transition-fast: 120ms`; `--transition-normal: 200ms` (bold, per spec); `--ease-standard: cubic-bezier(0.34, 1.56, 0.64, 1)` (energetic overshoot).\n- **Stacking:** `--z-dropdown: 100`; `--z-modal: 200`; `--z-toast: 300`.\n- **Contrast pairing is mandatory for every surface:** navy\u002Fblue backgrounds pair with white\u002F`#fefefe` text; yellow backgrounds pair with `#1a1a2e` text. Verify ≥ 4.5:1 for body text and ≥ 3:1 for large display text.\n\n**1.3 Mandatory Dark Mode — Explicit Dark-Only Exception**\nDark mode must always be defined. **Exception for this theme:** Creative Voltage is specified dark-only (\"Light: ✗ No \u002F Dark: ✓ Full\") — therefore define the dark palette as the single canonical theme directly in `:root`; do not build a light palette, a theme toggle, or `localStorage` persistence. Keep tokens structured so a light theme could later be added via a class without HTML changes.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with Flexbox. Every flex container defaults to `align-items: center` unless a documented exception exists (e.g., card bodies using `flex-start` for text alignment — justify in a CSS comment).\n- Mobile-first: split panels, card rows, steps, and pricing tiers collapse to a single column below 768px. No horizontal scrolling at any viewport from 320px upward.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS (CDN) or clean custom CSS driven by `@layer` \u002F `@apply`. Every utility must map back to the CSS variables or generic reusable classes: `.btn`, `.card`, `.input-group`, `.neon-badge`, `.halftone`, `.panel--blue`, `.panel--dark`, `.accordion`, `.toast`.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load via Google Fonts: Syne (700;800), Space Mono (400;700), Caveat (600;700). Bind `--font-display: 'Syne'`; `--font-base: 'Space Mono'`; `--font-script: 'Caveat'`.\n- Icons: Google Material Symbols (Outlined) icon font only. Raw inline SVGs and local icon files are forbidden.\n- Halftone textures are pure CSS: `.halftone { background-image: radial-gradient(circle, #000 1px, transparent 1px); background-size: 8px 8px; opacity: 0.1 }` for blue\u002Flight surfaces, plus a `.halftone--light` variant (white dots, opacity ≈ 0.08) for navy surfaces. No image files.\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component**\n- **Base `.btn`:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target; Space Mono 700 uppercase with letter-spacing; `border-radius: var(--radius-sm)`.\n- **Variants:** `.btn--primary` (blue bg, white text), `.btn--neon` (yellow bg, `#1a1a2e` text), `.btn--ghost` (transparent, 2px border), `.btn--danger` (visually distinct coral\u002Fred in the dark theme).\n- **Hover:** brightness shift + neon glow (`var(--glow-yellow)` \u002F `var(--glow-blue)`); `cursor: pointer`.\n- **Focus:** distinct 3px yellow focus ring (`outline` + offset) visible on both blue and navy.\n- **Active\u002Fpressed:** `transform: scale(0.97)`.\n- **Loading:** `.is-loading` blocks pointer events and double submits; CSS border spinner or animated Material icon; button dimensions must not change.\n- **Disabled:** `opacity: 0.5`; greyscale; `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback styles driven by `--text-success` \u002F `--text-error` (used by the Final CTA submit flow).\n\n**2.2 Card Component** (features, testimonials, pricing tiers)\n- **Default:** flex column, `--bg-secondary` surface, 1px `--border-default`, `--radius-md`.\n- **Hover:** `transform: translateY(-2px)` plus shadow\u002Fglow shift.\n- **Focus-within:** border shifts to `--secondary` when a child link\u002Fbutton receives focus.\n- **Loading skeleton:** `.card--skeleton` with a CSS shimmer animation and stable dimensions (no layout jumps).\n- **Empty state:** reusable pattern — Material icon plus short guidance text.\n\n**2.3 Form & Input Requirements** (Final CTA email capture)\n- **Structure:** `.input-group` flex container wrapping a `\u003Clabel>`, the `\u003Cinput>`, and a dedicated error-feedback element (flex row with error icon).\n- **States:** empty, focused (yellow ring), filled, valid (success border + check icon), invalid (error border, `--text-error` message, error icon), disabled, read-only.\n- Errors are tied via `aria-describedby`; success\u002Ferror announced in an `aria-live=\"polite\"` region.\n\n**2.4 Modal \u002F Popup Requirements** (apply if any dialog is used, e.g., a hero showreel)\n- **States:** opening, open, loading, success\u002Ferror, closing — all animated with 200ms CSS transitions.\n- **UX:** centered flex overlay (`align-items: center`) with backdrop; Material icon close button; keyboard focus trap; close via `Esc` and overlay click; `role=\"dialog\"` + `aria-modal`.\n- The FAQ section uses an accordion, not modals (spec in Section 0).\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid type via `clamp()`; zero horizontal overflow from 320px to 1440px; `scroll-margin-top` on anchor targets under the sticky header; smooth scrolling disabled under `prefers-reduced-motion`.\n- **Smooth animations:** `transition: var(--transition-normal)` (200ms) on all state changes; energetic hover transforms via `--ease-standard`; respect `prefers-reduced-motion` (disable marquee, transforms, shimmer, smooth scroll).\n- **Accessibility (a11y):** AA contrast throughout the dark theme; never rely on color alone — pair every state with an icon or text; semantic HTML5 landmarks (header\u002Fnav\u002Fmain\u002Fsection\u002Ffooter); skip-to-content link; logical DOM\u002Ffocus order; full keyboard operability (nav, accordion, pricing toggle, form); `aria-live` regions for form feedback and toasts (`.toast` rendered at `--z-toast`).\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Destructive actions** (if any appear) must be visually distinct via `.btn--danger` in the dark theme.\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File structure:** separate `index.html`, `style.css`, and `script.js`. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference.\n- **Naming convention:** one consistent BEM system (`block__element--modifier`) across HTML, CSS, and JS — the spec's `.neon-badge` and `.halftone` remain as block names; `.panel-dark` is implemented as `.panel--dark`. Never mix conventions.\n- **No unrequested placeholders:** author realistic English copy for the fictional brand; use `\"#\"` placeholder hrefs only for genuinely unspecified destinations (e.g., social profiles). No lorem ipsum.\n- **Ship complete, functional code on the first attempt:** sticky nav with working anchors, marquee, accordion, pricing toggle, form validation states, and toast feedback all operational.\n",1791954984985]
