## 0. PROJECT BRIEF & DESIGN DIRECTION

**Theme:** Vaporwave — nostalgic, pastel, surreal, digital. Retro-futuristic 1980s–90s aesthetic: synthwave, neon, glitch, sunset gradients, dreamy atmosphere, VHS effects, retro grid horizons.

**Product Concept:** Invent one coherent fictional product that fits the theme (e.g., a retro-futuristic music streaming service for "lost 80s frequencies," a synthwave audio toolkit, or a nostalgia media platform). Author all copy in polished English marketing voice consistent with that single concept. **No lorem ipsum anywhere.**

**Required Sections (in this order):** Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ → Final CTA → Footer with secondary links. A sticky header/nav with a theme toggle is required supporting chrome.

**Aesthetic Direction:**
* **Dark-focused:** the dark palette is the canonical look; light mode is a pastel daytime variant. Both must be fully designed.
* **Sunset gradients:** pink `#FF71CE` → cyan `#01CDFE` → purple `#B967FF`.
* **Signature effects:** neon `text-shadow` glow on display text, glitch animations on the hero headline, perspective retro grid floor, VHS scanline overlay, subtle ambient `filter: hue-rotate()` on decorative layers.
* **Imagery:** decorative atmosphere (sun disc, grid horizon, palm/statue motifs) is rendered in pure CSS (gradients/shapes). Where a photographic asset is genuinely needed (e.g., testimonial avatars), use a remote placeholder image URL with descriptive `alt` text. **Exception clause:** the "no inline SVG" rule below is absolute — do not inline SVGs even for decorative art; achieve it with CSS or remote images only.

## 1. STRICT RULES & ARCHITECTURE

**1.1 CSS-First Architecture & Zero Inline CSS**
* All styling lives in `style.css`. The `style="..."` attribute is forbidden in HTML.
* All design properties, layout rules, and states are targeted via class or ID selectors only.
* HTML must remain semantic and visually agnostic: re-theming the site requires editing only `style.css`, never the markup.

**1.2 CSS Variables (`var(--...)`) & Theme Tokens**
Store every visual token in `:root`, overridden per theme class:
* **Colors:** `--primary: #FF71CE` (neon pink), `--secondary: #01CDFE` (cyan), `--accent-mint: #05FFA1`, `--accent-purple: #B967FF`, plus `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.
* **Gradient tokens:** `--gradient-sunset` (the 180° pink→cyan→purple gradient) and derived tokens for gradient text, sun disc, and glow shadows.
* **Contrast Pairing:** light backgrounds pair with dark text, dark backgrounds with light text — enforced for both themes. Body text must meet WCAG AA (≥4.5:1). Neon hues are reserved for large display text (≥3:1), borders, glows, and accents — never for long body copy. In light mode, body text is a dark purple on pastel surfaces; neons appear only as accents.
* **Dark mode (canonical):** deep night purple backgrounds (e.g., `#12081f` / `#1c0f33` family) with near-white lavender text. **Light mode:** pastel lavender/mist background (e.g., `#f3ecff`) — never pure white; use `#fefefe` only where a near-white surface card is required.
* **Radius & shadows:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`, plus neon glow tokens (e.g., `--glow-pink`, `--glow-cyan`).
* **Spacing & transitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.
* **Elevation:** `--z-dropdown`, `--z-modal`, `--z-toast`, plus a low decorative overlay token; layered components must never conflict.

**1.3 Mandatory Dark Mode Support**
* Define dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`. Switching themes must never require HTML restructuring.
* Provide a visible toggle in the header with correct `aria-pressed` and `aria-label` ("Toggle dark mode").
* Persist choice via `localStorage`; fall back to `prefers-color-scheme` on first visit. **Exception clause:** a single minimal inline `<head>` snippet that applies the stored theme before first paint is the only permitted inline script (to prevent flash-of-wrong-theme); all other JS lives in `script.js`.

**1.4 Flexbox Layout & Mobile-First Alignment**
* Build all layout structures with Flexbox (`display: flex` / Tailwind flex utilities). Multi-card rows use `flex-wrap` with `flex-basis`, collapsing to a single column on mobile.
* Every flex container defaults to `align-items: center` unless a documented exception exists (text-heavy card/step bodies may use `flex-start` for readability).
* Mobile-first: no horizontal scrolling at any viewport ≥320px; rows convert to columns at breakpoints.

**1.5 Framework Default & Tailwind CSS Integration**
* Use Tailwind CSS (CDN acceptable) as the framework. Map all utilities back to the CSS variables; complex vaporwave effects live in `style.css` via Tailwind's `@layer` / `@apply` or plain CSS bound to the tokens.
* Generic reusable component classes required: `.btn`, `.card`, `.input-group`, `.badge`, `.accordion`.

**1.6 Typography & Icons (Google Fonts Mandatory)**
* **Fonts (Google Fonts only):** display font for headlines/logo (e.g., `Audiowide` or `Orbitron` — pick one), body font (e.g., `Exo 2` or `Inter`), and a retro mono accent font (e.g., `VT323`) for step numbers/labels. Bind them to `--font-display`, `--font-base`, `--font-mono` and load via `<link>` or `@import`.
* **Icons:** Google Material Symbols exclusively (e.g., `graphic_eq`, `cassette`, `headphones`, `blur_on`, `wb_twilight`, `waves`, `explore`, `check`, `close`, `menu`, `dark_mode`, `light_mode`, `arrow_forward`). Raw inline SVGs and local icon files are forbidden.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Button Component**
All states via CSS classes on `.btn` (flex layout, `align-items: center; justify-content: center; gap: 0.5rem`, minimum 44×44px touch target, Material Symbol + label):
* **Default:** primary variant uses the sunset gradient with neon glow shadow; secondary variant is a neon outline; ghost variant is transparent.
* **Hover:** brightness/shadow shift with `cursor: pointer`.
* **Focus-visible:** distinct neon focus ring via `outline`/`box-shadow` using tokens.
* **Active:** `transform: scale(0.97)` click feedback.
* **Loading:** disables interactions, prevents double-clicks, renders a CSS spinner or animated Google Icon without changing button dimensions (used on the newsletter/CTA form submit).
* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
* **Success/Error:** temporary feedback states driven by `--text-success` / `--text-error`.

**2.2 Card Component** (Features, Testimonials, Pricing tiers)
* **Default:** flexible flexbox column, `--bg-secondary` surface, `--border-default` border, `--radius-lg`, `--shadow-sm`.
* **Hover:** `transform: translateY(-2px)` plus a neon glow shadow shift.
* **Focus-within:** border highlights when a child link/button is focused.
* **Loading (Skeleton):** define shimmer animation styles in CSS (no layout jumps) for any async area.
* **Empty State:** define a fallback pattern — Google Icon plus clear guidance text — even if unused on first render.

**2.3 Form & Input Requirements** (newsletter capture in Final CTA)
* **States:** empty, focused (cyan ring), filled, valid (mint border + `check` icon), invalid (error border, error text, `error` icon, message in a dedicated error container with `aria-live="polite"`), disabled, read-only.
* **Structure:** flex `.input-group` wrapping `<label>`, `<input type="email">`, and a dedicated error feedback container.

**2.4 FAQ Accordion (custom widget — ARIA mandatory)**
* Each item: `<button aria-expanded>` + `<span>` chevron Material icon + panel with `role="region"` and `aria-labelledby`. `aria-controls` IDs must match panels.
* Animated open/close via CSS transitions; chevron rotates; state is never communicated by color alone; fully keyboard operable.

**2.5 Modal / Popup (conditional)**
Only if you add a "Watch Demo"/`play_arrow` trigger in the Hero. If present: centered flex overlay + backdrop, Google Icon close button, focus trapping, `Esc` and overlay-click closing, animated opening/closing states. **If you do not include a modal, do not add one — no unrequested features.**

## 3. CORE UX & MICRO-INTERACTION RULES

* **Responsive by default:** fluid `clamp()` typography; no horizontal overflow.
* **Smooth animations:** `transition: var(--transition-normal)` on all state changes. **`prefers-reduced-motion: reduce` MUST disable** glitch keyframes, hue-rotate drift, scanline flicker, grid scroll, and smooth scrolling — substituting instant, opacity-only changes.
* **Accessibility:** WCAG AA contrast in both themes; never rely on color alone for state; semantic HTML5 (`header`, `nav`, `main`, `section`, `article`, `footer`); correct ARIA roles/labels on the accordion, mobile nav toggle, and theme toggle; logical DOM/focus order; full keyboard operability; `aria-live` regions for form feedback and loading states.
* **Mandatory visual feedback:** every hover, click, link, and submission triggers a visible state change.
* **Destructive actions:** none are expected in a landing page; if any reset/clear control is added, style it as a distinct `.btn-danger` visible in both themes.

---

## 4. DELIVERABLE & OUTPUT FORMAT

* **Files:** separate `index.html`, `style.css`, `script.js`. Only script reference is one deferred `script.js` (plus the single permitted pre-paint theme snippet in `<head>` per §1.3).
* **Naming convention (one, never mixed):** Tailwind utilities for layout/spacing plus the fixed generic component vocabulary from §1.5 and a fixed effect-utility set from §6. No BEM, camelCase, or ad-hoc names.
* **Copy:** authored, thematic, realistic English marketing copy for every section (headlines, feature descriptions, step explanations, testimonial quotes with names/roles, three priced tiers with feature lists, 5–6 FAQ Q&As). Lorem ipsum is prohibited.
* **Completeness:** all 8 sections + header built in one pass; no TODOs, no stubs.

---

## 5. SECTION-BY-SECTION BUILD SPECIFICATIONS

* **5.1 Header (sticky):** gradient/glow wordmark logo in `--font-display`, anchor links to each section, theme toggle; on mobile, an accessible hamburger (`aria-expanded`, `aria-controls`) with a column dropdown and backdrop blur.
* **5.2 Hero:** full-height (`min-height: 90vh`) centered flex column. Headline in display font with layered `text-shadow` neon glow and the `.fx-glitch` treatment; supporting subheadline; two CTAs (primary gradient button + outlined secondary). Backdrop: CSS sun disc with retro slats, `.fx-grid-floor` perspective horizon, and floating decorative Material Symbols.
* **5.3 Features:** section heading + 3 `.card`s (icon tile with neon gradient, title, copy). Optional "Learn more" link per card (if present, `:focus-within` must highlight the card).
* **5.4 How It Works:** 3 steps in a responsive flex row; mono-font step numbers (01/02/03), Material Symbol, title, copy; a neon connector line on desktop that collapses gracefully on mobile.
* **5.5 Testimonials:** 3 quote cards with oversized quotation glyph, avatar (remote placeholder image with `alt`, or CSS initials monogram), name, role; card hover glow.
* **5.6 Pricing:** 3 tier cards; the middle tier is featured — elevated, gradient border/glow, and a "MOST POPULAR" `.badge` (never color-only). Each card: tier name, large display-font price, feature list with `check` icons, CTA button.
* **5.7 FAQ:** accordion per §2.4; the first item may start expanded with `aria-expanded="true"`; all others closed.
* **5.8 Final CTA:** full-width sunset-gradient band or glowing bordered panel; large glowing headline; newsletter `.input-group` per §2.3 whose button demonstrates loading → success (mint border + `aria-live` confirmation) or error states.
* **5.9 Footer:** flex column on mobile, row of columns on desktop — logo/tagline, secondary link groups (Product, Company, Legal), Material Symbol social icons with `aria-label`s, copyright line, and a "Back to top" link. All links keyboard-focusable with visible focus rings.

## 6. VAPORWAVE EFFECT IMPLEMENTATION REQUIREMENTS

Define these as a fixed, documented utility set in `style.css` (all reduced-motion safe):
* **`.fx-glow-text`:** layered neon `text-shadow` using token colors.
* **`.fx-gradient-text`:** sunset gradient via `background-clip: text` with a solid fallback color.
* **`.fx-glitch`:** RGB-split glitch on the hero headline via pseudo-elements reading `attr(data-text)` (set the `data-text` attribute on the headline), animated with `clip-path` slices and cyan/pink offsets; triggers subtly at idle and on hover; fully disabled under reduced motion.
* **`.fx-grid-floor`:** retro horizon — container with `perspective()`, floor drawn from `linear-gradient`/`repeating-linear-gradient` lines in both axes, slow scroll animation (reduced-motion safe).
* **`.fx-scanlines`:** fixed full-page `::after` overlay using `repeating-linear-gradient`, opacity ≤ 0.08, `pointer-events: none`, optional subtle flicker (reduced-motion safe).
* **`.fx-hue-drift`:** slow ambient `filter: hue-rotate()` animation applied to decorative layers only (sun, grid) — never to text, buttons, or interactive controls.
* **Performance:** animate only `transform`/`opacity` (plus the limited `filter` on small decorative layers); keep keyframe counts minimal; verify both themes and all breakpoints before delivering.
