Your task is to code a complete, production-ready landing page **on the first attempt** — no drafts, no partial output, no clarifying questions. Generate the final code immediately, following every rule in this specification. Where this spec is silent, make the most accessible, most on-theme decision and proceed.\n\n**Objective:** A single-page marketing site in the **Aurora** theme (Fantasy & Sci-Fi category) with the following sections, in this order: **Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links** — plus a sticky glass navigation bar.\n\n**Product concept (commit to one, keep all copy consistent):** *Aurora* — an AI-powered \"dream canvas\" that turns ideas into living, luminous art. All user-facing copy is written in **English**, in a dreamy, cosmic, wonder-filled tone. Lorem ipsum is prohibited.\n\n---\n\n## 0. THEME DEFINITION — \"AURORA\"\n\n**Mood:** Dreamy, luminous, gradient-driven, cosmic. A 2020s digital-art aesthetic inspired by the aurora borealis — fluid color that drifts and breathes over deep night skies. Dark mode is the **primary** experience; light mode is a softer, luminous variant.\n\n**Palette (bind every color to a CSS variable — no raw hex values inside component rules):**\n- Primary: Aurora Purple `#7B2FBE`, Cosmic Pink `#FF6B9D`, Deep Blue `#1A0533`, Emerald Glow `#00D4AA`\n- Secondary: Soft Lavender `#C4A1FF`, Sky Cyan `#67E8F9`, Warm Rose `#FFB3C6`, Midnight `#0A0A1A`\n\n**Signature effects (apply consistently across the page):**\n- **Multi-stop gradients (3–5 colors):** `linear-gradient(135deg, #1A0533, #7B2FBE, #FF6B9D, #00D4AA)` for aurora bands, the Final CTA panel, and gradient borders. Gradient headline text uses luminous stops on dark (`#C4A1FF → #FF6B9D → #67E8F9`) and deep stops on light (`#7B2FBE → #FF6B9D → #1A0533`).\n- **Backdrop blur (15–25px):** glassmorphic cards, nav, and modal surfaces (`backdrop-filter: blur(20px)` with the `-webkit-` prefix).\n- **Grain overlay:** subtle SVG-turbulence noise via `filter: url(#grain)` (see the exception clause in 1.6).\n- **Fluid transitions:** 600ms ease on color, gradient, and theme shifts.\n- **Glow on hover:** `box-shadow: 0 0 60px rgba(123,47,190,0.3)` plus pink and emerald glow variants.\n- **Radial gradient backgrounds:** layered radial \"aurora curtains\" drifting behind sections.\n- **Radius:** 16px default surface radius.\n\n**Contrast guardrails (mandatory):**\n- The full 4-stop gradient is **decorative only** — never place body text directly on its pink\u002Femerald stops. Where text sits on a gradient panel (Final CTA), add a dark overlay (e.g., `rgba(10,10,26,0.55)`) beneath the text.\n- Primary buttons use a purple-only gradient deep enough for white text (e.g., `#6B22A6 → #8B3FC7`); never place white labels on pink or emerald gradient stops.\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 `index.html`.\n- **Class\u002FID selectors only:** every design property, layout rule, and state lives in `style.css`, targeted via classes\u002FIDs.\n- **Minimal HTML modifications:** markup stays semantic and style-agnostic (`header`, `nav`, `main`, `section`, `footer`, `h1–h3`, `p`, `ul`, `form`, `button`, `details`). Reskinning the site must require editing `style.css` only, never the markup.\n\n**1.2 CSS Variables & Theme Tokens**\n- Define all tokens in `:root` (light) and override under both `.dark` and `@media (prefers-color-scheme: dark)`:\n  - **Colors:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`, plus Aurora extensions: `--accent-glow`, `--glass-bg`, `--focus-ring`, `--gradient-aurora`, `--glow-primary`, `--glow-pink`, `--glow-emerald`.\n  - **Light mode:** `--bg-primary` is a soft lavender wash (e.g., `#F4F0FF`) — never pure white; use `#fefefe` only where a near-white surface is genuinely required. `--text-primary: #1A0533`.\n  - **Dark mode:** `--bg-primary: #0A0A1A`, `--bg-secondary: #1A0533`, `--text-primary: #F2EDFF`, `--text-secondary: #C4A1FF`, `--text-success: #00D4AA`, `--text-error: #FF5252` (a true red, visually distinct from Cosmic Pink).\n  - **Contrast pairing:** every light background token pairs with a dark text token and every dark background token with a light text token — enforced in both themes. Success\u002Ferror tokens must pass WCAG AA on their theme's surfaces.\n  - **Radius & shadows:** `--radius-sm: 8px`, `--radius-md: 12px`, `--radius-lg: 16px`, `--shadow-sm`, `--shadow-md`.\n  - **Spacing & transitions:** `--spacing-gap`, `--transition-fast: 200ms`, `--transition-normal: 600ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`. Use `--transition-normal` for aurora color\u002Ftheme drift and `--transition-fast` for hover\u002Fpress micro-feedback. Prefer explicit transition properties over `transition: all`.\n  - **Stacking:** `--z-bg: 0`, `--z-grain: 50`, `--z-dropdown: 100` (nav), `--z-modal: 1000`, `--z-toast: 1100` — layered components must never conflict.\n\n**1.3 Mandatory Dark Mode Support**\n- Dark mode is the primary Aurora experience; **both modes must be fully defined**.\n- Provide dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`, so switching never requires HTML restructuring.\n- Persist the user's choice in `localStorage`; fall back to `prefers-color-scheme` on first visit. Run theme initialization as the first statements in `script.js` to avoid a flash of the wrong theme.\n- Provide a visible toggle in the nav (sun\u002Fmoon Google Material Symbols) with correct `aria-pressed` and dynamic `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\"), swapping icons per state.\n- Aurora background bands stay vibrant in both modes; adjust band opacity\u002Fblend per theme via variables only.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build every layout structure with Flexbox. **Every flex container defaults to `align-items: center`** unless an exception is explicitly justified in a CSS comment.\n- **Mobile-first:** multi-column rows (features, steps, testimonials, pricing, footer columns) wrap into a single column on small viewports. No horizontal scrolling at any width — clip the fixed aurora background (`overflow-x: hidden` on `body` or `overflow: clip` on the background layer) and mark all decorative layers `pointer-events: none`.\n\n**1.5 Framework & CSS Architecture**\n- Per the theme's raw-CSS technical specification, deliver **clean, hand-authored modern CSS** in `style.css` (the custom-CSS allowance of the framework rule), organized in clear layers: base → layout → components → utilities. Do not add framework CDN scripts. All reusable classes (`.btn`, `.card`, `.input-group`) must map back to the CSS variables.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- **Text:** Google Fonts only — **Space Grotesk** for display headings (bound to `--font-display`) and **Inter** for body text (bound to `--font-base`). Include preconnect and stylesheet `\u003Clink>` tags.\n- **Icons:** Google **Material Symbols Rounded** via the official stylesheet (use `font-variation-settings`, e.g., `FILL 1`, for filled icons such as stars). Raw inline SVG icons and local icon files are forbidden.\n- **Exception clause (theme-mandated):** the Aurora grain texture requires `filter: url(#grain)`. Exactly one hidden `\u003Csvg>` block containing `\u003Cdefs>\u003Cfilter id=\"grain\">` (feTurbulence noise) is permitted in `index.html`, marked `aria-hidden=\"true\"`. This is the only inline SVG allowed; every icon must still be a Material Symbol. If the SVG filter proves too GPU-intensive, an equivalent noise `background-image` (inline data-URI inside `style.css`) may substitute — the grain effect itself must never be dropped.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\nAll state styles must be defined via CSS classes using BEM.\n\n**2.1 Buttons (`.btn`, `.btn--primary`, `.btn--secondary`, `.btn--danger`)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px, `border-radius: var(--radius-md)`.\n- **Primary:** purple gradient fill per the contrast guardrails, white text. **Secondary:** glass surface (`--glass-bg`, blur, 1px `--border-default`).\n- **Hover:** glow (`--glow-primary`) plus a brightness shift; `cursor: pointer`.\n- **Focus:** distinct `:focus-visible` ring using `--focus-ring` (Sky Cyan on dark, Aurora Purple on light) via `outline`\u002F`box-shadow`.\n- **Active\u002Fpressed:** `transform: scale(0.97)`.\n- **Loading (`.btn--loading`):** disables interaction, prevents double-clicks, renders a CSS spinner or animated Material Symbol without distorting button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`, no hover glow.\n- **Success\u002FError (`.btn--success`, `.btn--error`):** temporary feedback driven by `--text-success` \u002F `--text-error`, always paired with an icon and `aria-live` text — never color alone.\n- **`.btn--danger`:** a distinct red treatment legible in both light and dark themes; define it in the stylesheet even if the page contains no destructive action.\n\n**2.2 Cards (`.card` and variants)**\n- **Default:** flexible flex layout, glass surface (`--glass-bg` + `backdrop-filter: blur(20px)`), 1px `--border-default`, `border-radius: var(--radius-lg)`, subtle `--shadow-sm`.\n- **Hover:** `transform: translateY(-2px)` plus an intensified glow shadow.\n- **Focus-within:** border shifts to `--focus-ring` when a child link\u002Fbutton receives focus.\n- **Loading (`.card--skeleton`):** shimmer keyframe animation defined in CSS, sized to prevent layout jumps.\n- **Empty (`.card--empty`):** structured fallback layout with a Google Material Symbol and clear guidance text, defined in CSS.\n\n**2.3 Forms & Inputs (`.input-group`)**\n- **Structure:** flex container wrapping a `\u003Clabel>`, the input field, and a dedicated error-feedback element with `aria-live=\"polite\"`.\n- **States — all styled:** empty, focused (`--focus-ring` ring), filled, valid (Emerald Glow border + check icon), invalid (`--border-error`, error icon, red error text), disabled, read-only.\n- Labels may be visually hidden only where a visible label is impractical (email captures); the `\u003Clabel for>` association must still exist.\n\n**2.4 Modal (`.modal`) — required once: the featured pricing tier's CTA opens a \"Start your journey\" signup modal**\n- **States:** opening (fade\u002Fscale-in), open, loading (submit button spinner), success (check icon + confirmation, then auto-close), error, closing (fade-out) — all animated via CSS transitions.\n- **UX:** centered flex container (`align-items: center; justify-content: center`), dark translucent backdrop with blur, Material Symbol close button (top-right, 44×44px), keyboard focus trapped while open, close via `Esc` and overlay click, background scroll locked, focus returned to the trigger on close, `role=\"dialog\"`, `aria-modal=\"true\"`, labelled by the modal title.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid type via `clamp()`, mobile-first breakpoints, zero horizontal overflow.\n- **Smooth animations:** all state changes transition (`--transition-fast` for interactions, `--transition-normal` for aurora drift); background aurora bands animate with slow transform keyframes (20–35s, alternate). **`prefers-reduced-motion`: disable band drift, bouncing cues, and shimmer; make state changes instant.**\n- **Accessibility (a11y):** WCAG AA contrast in both modes (verify gradient text, glass surfaces, and glow states); never rely on color alone to communicate state; semantic HTML5; correct ARIA roles\u002Flabels on the nav toggle, accordion, modal, and forms; logical DOM\u002Ffocus order; full keyboard operability; `aria-live` regions for form errors, loading, and success feedback.\n- **Mandatory visual feedback:** every click, hover, focus, and submission triggers a visible state change.\n- **Sticky nav:** glass bar with `backdrop-filter: blur(20px)` over `--glass-bg`; anchor links use `scroll-behavior: smooth` and `scroll-padding-top` for the nav offset (smooth scrolling disabled under reduced motion).\n\n---\n\n## 4. PAGE STRUCTURE & SECTION REQUIREMENTS\n\nHeading hierarchy: exactly one `\u003Ch1>` (Hero), one `\u003Ch2>` per section, `\u003Ch3>` inside cards\u002Fsteps. Every content section opens with an eyebrow label, a gradient-text `\u003Ch2>`, and a supporting paragraph.\n\n**4.1 Navigation (`.nav`)** — sticky glass bar: logo (Material Symbol \"auto_awesome\" + \"Aurora\" wordmark in `--font-display`), anchor links (Features, How It Works, Testimonials, Pricing, FAQ), the theme toggle (1.3), and a primary CTA. Mobile: links collapse behind a hamburger button with `aria-expanded` \u002F `aria-controls`, closing on link click and `Esc`.\n\n**4.2 Hero (`.hero`)** — full-viewport (`min-height: 100vh` with a `100svh` fallback) flex column, centered, over the drifting aurora field and grain. Contents: a glass badge chip (sparkle icon + short label), `\u003Ch1>` in gradient text at the largest `clamp()` size, a supporting subheadline, a CTA row (`.btn--primary` \"Start creating\" + `.btn--secondary` \"See how it works\" scrolling to How It Works), and a row of three small glass stat chips (e.g., \"120k dreamers\", \"4.9 rating\", \"Free to start\"). Optional scroll cue (Material Symbol \"keyboard_arrow_down\", gentle bounce, reduced-motion safe).\n\n**4.3 Features (`.features`)** — section header plus 3 glass cards in a flex row (wrapping to a column on mobile). Each card: a gradient icon tile (Material Symbol, e.g., \"brush\", \"auto_awesome\", \"hub\") with glow, an `\u003Ch3>` title, and a 2–3 sentence description. Hover\u002Ffocus states per 2.2.\n\n**4.4 How It Works (`.how`)** — 3 steps in a flex row (column on mobile), connected by a horizontal gradient line on desktop only. Each step: an oversized gradient number (01\u002F02\u002F03), a Material Symbol, an `\u003Ch3>`, and a description, following a \"describe → generate → share\" narrative arc.\n\n**4.5 Testimonials (`.testimonials`)** — 3 glass cards: a 5-star row (Material Symbol \"star\", filled, Cosmic Pink), the quote, a divider, and an author row (gradient circular avatar with initials, name, role). Fictional but realistic names and roles consistent with the product concept.\n\n**4.6 Pricing (`.pricing`)** — 3 tier cards (flex row → column): **Stardust** (free), **Nebula** (featured: \"Most popular\" badge, gradient border via the padding technique, stronger glow, slight scale-up), **Supernova** (premium). Each card: tier name, monthly price, short pitch, a feature list with Material Symbol \"check_circle\" in Emerald Glow, and a CTA. The featured tier's CTA opens the signup modal (2.4); the other tiers' CTAs anchor to the Final CTA form.\n\n**4.7 FAQ (`.faq`)** — 5 questions as a native `\u003Cdetails>\u002F\u003Csummary>` accordion: default marker removed, `cursor: pointer`, Material Symbol \"expand_more\" rotating 180° when open, smooth open\u002Fclose transition where supported, visible `:focus-visible` ring on the summary. Real questions and answers about the product.\n\n**4.8 Final CTA (`.cta`)** — full-width panel with the 4-stop aurora gradient, dark overlay, grain, and glow. Headline, subheadline, and an inline email-capture `.input-group` (visually hidden label, email input with all 2.3 states, `.btn--primary` submit). Submit → button loading state → inline success message (Emerald Glow check icon + text) announced via `aria-live`; invalid email → inline error message with error icon.\n\n**4.9 Footer (`.footer`)** — deep-toned panel: brand block (logo + one-line tagline), 3–4 secondary link columns (Product, Company, Resources, Legal — real English labels; `href=\"#\"` is acceptable only because no real URLs were supplied), a social\u002Fcommunity row using Material Symbols or text labels (inline SVG brand icons are forbidden), and a copyright line with the year injected by JS.\n\n---\n\n## 5. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** `index.html`, `style.css`, `script.js` — three separate files. The only script reference is a single `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`. No inline `\u003Cscript>` blocks, no inline styles, no inline event handlers (`onclick` etc. are forbidden — bind with `addEventListener`). `index.html` must include `lang=\"en\"`, the viewport meta, a descriptive `\u003Ctitle>`, and a meta description.\n- **Naming convention:** BEM everywhere — one convention, never mixed (e.g., `.hero__title`, `.card--featured`, `.pricing__card`, `.modal__overlay`).\n- **Copy:** real, polished English marketing copy in the Fantasy & Sci-Fi tone. Lorem ipsum is prohibited; neutral placeholders are permitted only where the user supplied no real destination or content.\n- **JS scope (vanilla, minimal):** theme initialization\u002Ftoggle with persistence (runs first), mobile nav toggle, modal open\u002Fclose with focus trap, both form validations with loading\u002Fsuccess\u002Ferror states, and the footer year. Nothing beyond this list.\n- **First attempt:** output the complete final code for all three files in a single response.\n",1791954986056]
