## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
- **No Inline CSS:** The `style="..."` attribute is forbidden anywhere in the HTML.
- **Class/ID Selectors Only:** All design properties, layout rules, and states must be targeted via class or ID selectors defined in `style.css`.
- **Minimal HTML Modifications:** HTML must remain clean, semantic (HTML5 landmarks: `header`, `nav`, `main`, `section`, `footer`), and agnostic of visual styling. Re-theming the page must require editing only the CSS file.

### 1.2 CSS Variables (`var(--...)`) & Theme Tokens
Store all visual tokens in `:root` (light/default) and override them in the dark theme (Rule 1.3):

- **Color Tokens (required names):** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.
- **Light Mode Mapping (default):** `--bg-primary: #ece7f4` (soft retro lavender — never pure white; use `#fefefe` only where a near-white elevated surface is required), `--bg-secondary: #f6f2fb`, `--text-primary: #171226`, `--text-secondary: #3a2b5e`, `--primary: #2a2140`, `--secondary: #3a2b5e`. Neumorphic shadows must be built from the palette: a light highlight shadow plus a deep purple shadow (e.g., `rgba(11, 9, 19, 0.25)`).
- **Dark Mode Mapping:** `--bg-primary: #0b0913`, `--bg-secondary: #171226`, `--text-primary: #ece7f4`, `--text-secondary: #b3a8d1`, `--primary: #3a2b5e`, `--secondary: #241a40`. Glow effects are amplified in dark mode via `box-shadow`/`text-shadow` with `rgba()` values derived from the palette.
- **Derived Accent:** One brighter neon violet (in the `#8b5cf6`–`#9d7bff` range) may be defined as `--accent-glow` for neon glow and gradient highlights in both themes. All other colors must come from the provided palette or `rgba()` derivatives of it.
- **Contrast Pairing:** Every light background token must pair with a dark text token and every dark background token with a light text token — enforce this in both themes, not just the default.
- **Radius & Shadows:** `--radius-sm: 4px`, `--radius-md: 8px`, `--radius-lg: 16px`, `--shadow-sm`, `--shadow-md`. Favor small radii for the pixel/arcade feel; larger radii only for pills and the cabinet screen.
- **Spacing & Transitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.
- **Elevation/Stacking:** `--z-dropdown`, `--z-modal`, `--z-toast` — apply to the mobile nav panel, any modal, and any toast/notification layer to prevent overlap conflicts.

### 1.3 Mandatory Dark Mode Support
- **Implementation:** Define dark mode tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`/`<body>`, so switching never requires HTML restructuring.
- **Theme Switching:** All backgrounds, text, borders, neumorphic shadows, and glows must flip seamlessly via the CSS variables only.
- **Persistence:** Persist the user's choice in `localStorage`. **Exception clause:** because the style spec explicitly selects Light as the default mode, first visit defaults to Light mode (overriding the `prefers-color-scheme` fallback); after the user toggles once, always honor the stored choice.
- **Toggle Control:** A visible toggle in the header using a Google Material Symbols icon (`light_mode` / `dark_mode`) with correct `aria-pressed` and `aria-label` state.

### 1.4 Flexbox Layout & Mobile-First Alignment
- **Default Alignment Rule:** Every flex container must default to `align-items: center` unless an explicitly justified exception exists (document the exception in a CSS comment).
- **Mobile-Friendly First:** All layouts must be mobile-responsive out of the box — multi-column rows (Features, Pricing, Testimonials, footer link columns) collapse to a single column on small viewports. Prevent horizontal scrolling globally (`overflow-x` guard, fluid `clamp()` typography, `max-width` containers).

### 1.5 Framework Default & CSS Integration
- Use Tailwind CSS **or** a single well-organized custom `style.css` (preferred here, given the heavy custom retro effects). If Tailwind is used, all custom effects (scanlines, neumorphism, pixel borders, keyframes) must live in `@layer components` or dedicated CSS, and every utility must map back to the CSS variables or reusable class names (`.btn`, `.card`, `.input-group`).

### 1.6 Typography & Icons (Google Fonts Mandatory)
- **Text Fonts (Google Fonts only):** `Press Start 2P` for display headings/buttons (pixel arcade voice), `VT323` for accent labels, tickers, and HUD-style microcopy, and `Space Grotesk` (or `Inter`) for body copy. Bind them to `--font-display`, `--font-accent`, and `--font-base`. Include via `<link>` tags.
- **Icons:** Use Google Material Symbols exclusively (e.g., `sports_esports`, `bolt`, `palette`, `star`, `check_circle`, `close`, `menu`, `help`, `arrow_forward`, `light_mode`, `dark_mode`). **Inline SVGs, local icon files, and emoji-as-icons are forbidden.**

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Button Component Requirements
Style all states via CSS classes (`.btn`, `.btn--primary`, `.btn--secondary`, `.btn--ghost`, `.btn--danger`):
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` with a minimum 44×44px touch target. Arcade character: chunky hard bottom shadow (e.g., `box-shadow: 0 4px 0 <darker palette shade>`), pixel-style border, `--font-display` or `--font-accent` label.
- **Hover:** Brightness/glow shift with `cursor: pointer`.
- **Focus:** Distinct focus ring built from CSS variables (`outline` + `outline-offset` or `box-shadow`) for keyboard navigation.
- **Active/Pressed:** Arcade-button compression — `transform: translateY(3px)` combined with reducing the hard bottom shadow to `0 1px 0` (or `scale(0.97)`).
- **Loading (`.is-loading`):** Disables interaction, prevents double-clicks, renders a CSS spinner or animated Google Icon without distorting button dimensions.
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Success/Error:** Temporary feedback styles driven by `--text-success` / `--text-error`, always paired with an `aria-live` announcement.

### 2.2 Card Component Requirements
- **Default:** Flexible Flexbox layout styled with `--bg-secondary`, subtle `--border-default`, and neumorphic dual shadows (light highlight + deep purple shade in light mode; adapted darker pair in dark mode).
- **Hover:** Elevation/glow shift plus `transform: translateY(-2px)`.
- **Focus-within:** Card border highlights when a child link/button receives keyboard focus.
- **Loading (Skeleton):** Shimmer keyframe animation defined in CSS with stable dimensions to prevent layout jumps.
- **Empty State:** Structured fallback layout featuring a Google Icon and clear guidance text.

### 2.3 Form & Input Requirements
- **States:** Empty, Focused (outline ring), Filled, Valid (success border + `check_circle` icon), Invalid (error border, error text, error icon), Disabled, Read-only.
- **Structure:** A flex `.input-group` container wrapping a `<label>`, the input field, and a dedicated error feedback element with `aria-live="polite"`.
- **Usage:** Apply to the email capture in the Final CTA section.

### 2.4 Accordion (FAQ) & Modal Requirements
- **FAQ Accordion:** Each question is a `<button>` with `aria-expanded` and `aria-controls`; the answer panel animates open/closed via CSS transitions (`grid-template-rows: 0fr → 1fr` or `max-height`); a chevron Material icon rotates; fully keyboard operable.
- **Modal (if a "Watch Demo" modal is included):** Opening, Open, Loading, Success/Error, and Closing states all animated via CSS transitions; centered flex container (`align-items: center`), backdrop overlay, Google Icon close button, keyboard focus trapping, `role="dialog"`, `aria-modal`, and closing via `Esc` or overlay click.

## 3. LANDING PAGE SECTION SPECIFICATIONS

### 3.1 Header (Sticky)
Logo "CABINET 07" in `--font-display` with a layered `text-shadow` glow; nav links (Features, How It Works, Testimonials, Pricing, FAQ); theme toggle (Rule 1.3); accessible mobile hamburger menu (`aria-expanded`, `aria-controls`, animated slide-down panel using `--z-dropdown`). On scroll, the header gains a solid/blurred background via a JS-toggled class.

### 3.2 Hero
- Full-viewport Flexbox layout over an **animated purple gradient background** (keyframe gradient position shift) with a `mix-blend-mode` overlay layer and a subtle **CRT scanline overlay** (repeating-linear-gradient, gently animated).
- Floating pixel particles (pure CSS keyframes, `aria-hidden="true"`).
- Headline in `--font-display` with glow `text-shadow`; supporting copy in `--font-base`; two CTAs: **"PRESS START"** (`.btn--primary`) and **"INSERT COIN"** (`.btn--ghost`).
- **Signature visual:** a CSS-built arcade cabinet mock (no images) using `aspect-ratio` (cabinet ≈ 3/4, screen ≈ 4/3), tilted with `transform: rotate()` and a gentle "TILT" wobble keyframe; the screen shows a gradient plus blinking "READY PLAYER 1" text. Blinking must never be the sole carrier of information.

### 3.3 Features (3 cards)
Three `.card` components in a responsive flex/grid row: neumorphic surface, glowing Material icon badge (`sports_esports`, `bolt`, `palette` or similar), title, and copy. Hover lift + glow; `:focus-within` support; skeleton loading styles defined.

### 3.4 How It Works (3 steps)
Three steps with oversized pixel numerals (01 / 02 / 03) in `--font-accent`, a connecting dashed line on desktop, vertical stack on mobile, one Material icon per step, and scroll-triggered entrance animations.

### 3.5 Testimonials
Three cards: quote Material icon, quote copy, a 5-star rating (star icons **plus** an accessible text label — never color-only), a CSS initials-avatar circle (`aspect-ratio: 1`), and name/role. Optionally top the section with a "HIGH SCORES" marquee ticker (CSS keyframe scroll, pauses on hover, reduced-motion safe).

### 3.6 Pricing (3 tiers)
Three `.pricing-card` components; the middle tier is featured with a "TOP SCORE" badge, glow border, and elevated scale. Feature lists use `check_circle` icons; each tier has its own `.btn` CTA. If a monthly/annual toggle is included, it must use `aria-pressed` and announce price changes via `aria-live`.

### 3.7 FAQ
Five to six arcade-themed questions rendered as the accessible accordion defined in Rule 2.4.

### 3.8 Final CTA
Full-width gradient panel (palette purples, `mix-blend-mode`, glow) with a headline, a **"PRESS START"** button demonstrating the loading → success state sequence, and an email `.input-group` (Rule 2.3) with validation and `aria-live` feedback.

### 3.9 Footer
Secondary link columns (Games, Company, Support, Legal), social icons as Material Symbols with `aria-label`s, copyright line with a retro "© 199X–2025 CABINET 07" touch, and an optional blinking "INSERT COIN" easter egg.

## 4. CORE UX & MICRO-INTERACTION RULES
- **Responsive by Default:** Fluid sizing, `clamp()` typography, responsive breakpoints, zero horizontal overflow.
- **Smooth Animations:** CSS transitions on all state changes (`transition: var(--transition-normal)`); every keyframe effect (scanlines, blink, particles, marquee, wobble, gradient shift) must be disabled or reduced under `prefers-reduced-motion`.
- **Accessibility (a11y):** WCAG AA contrast in both Light and Dark modes; never rely on color alone to communicate state; semantic HTML5 elements; correct ARIA roles/labels on all custom widgets (toggle, accordion, mobile menu, modal); logical DOM/focus order; full keyboard operability; a skip-to-content link; `aria-live` regions for dynamic feedback (form errors, loading, toasts).
- **Mandatory Visual Feedback:** Every click, hover, and submission triggers a visible state change.
- **Destructive Actions:** Any destructive control (e.g., "Reset Progress") must use `.btn--danger` and be visually distinct in both themes.

---

## 5. DELIVERABLE & OUTPUT FORMAT
- **File Structure:** Separate `index.html`, `style.css`, and `script.js`. No inline `<script>` blocks beyond a single deferred entry point (`<script src="script.js" defer>`).
- **Naming Convention:** BEM (`block__element--modifier`) consistently across the entire deliverable — never mix conventions.
- **Copy:** All user-facing copy in English, written in-theme (e.g., "PRESS START", "INSERT COIN", "READY PLAYER 1", "HIGH SCORE", "CONTINUE?"). No lorem ipsum — write real, themed copy for every section.
- **JavaScript Scope:** Theme toggle with `localStorage` persistence, mobile nav, FAQ accordion, smooth anchor scrolling, IntersectionObserver scroll-reveals (content visible by default when JS is unavailable), CTA loading/success demo, and email validation. No external libraries or CDNs beyond Google Fonts and Google Material Symbols.
- **Output the complete, final code for all three files immediately — it must run correctly on the first attempt.**
