Build a complete, production-ready **Brutalist Landing Page** in a single attempt. Follow every rule below exactly. Do not ask clarifying questions — deliver the final code immediately.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n- All styling must live in a dedicated `style.css` file. **The `style=\"...\"` attribute is forbidden anywhere in the HTML.**\n- Target every element via class or ID selectors only.\n- HTML must remain semantic and clean; all visual changes happen in CSS only.\n\n### 1.2 CSS Variables & Theme Tokens\nDefine all tokens in `:root` and theme classes:\n\n- **Colors:** `--primary: #000000`, `--secondary: #FFFFFF`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success: #00FF00`, `--text-error: #FF0000`, `--border-default`, `--border-error`, `--border-success`.\n- **Accent tokens:** `--accent-neon-green: #00FF00`, `--accent-hot-pink: #FF00M` → correct to `#FF00FF`, `--accent-electric-blue: #0000FF`, `--accent-yellow: #FFFF00`, `--accent-grey: #808080`.\n- **Contrast Pairing:** Every light background token pairs with a dark text token and vice versa — enforced in both light and dark themes.\n- **Light Mode Background:** Do not use pure `#ffffff` as the page background; use `#fefefe` where near-white is required. Pure white is reserved for blocks\u002Fborders per the brutalist palette.\n- **Radius & Shadows:** `--radius-sm: 0px`, `--radius-md: 0px`, `--radius-lg: 0px` (brutalism = sharp corners, always). `--shadow-sm`, `--shadow-md` must be **hard offset shadows** (e.g., `8px 8px 0 #000000`) — no blur, no soft shadows.\n- **Spacing & Transitions:** `--spacing-gap`, `--transition-fast: none`, `--transition-normal: none`, `--ease-standard: none`. **All transitions are disabled** — state changes must be instant.\n- **Elevation:** `--z-dropdown`, `--z-modal`, `--z-toast`.\n\n### 1.3 Mandatory Dark Mode Support\n- Define dark tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class on `\u003Chtml>`\u002F`\u003Cbody>`.\n- Dark mode inverts: `--bg-primary: #000000`, `--text-primary: #FFFFFF`, borders flip to white, hard shadows become white\u002Fblack offset blocks.\n- Persist user choice via `localStorage` in `script.js`; fall back to `prefers-color-scheme` on first visit.\n- Include a visible theme toggle button with correct `aria-pressed` and `aria-label` states. The toggle itself must be brutalist: bordered block, monospace label (e.g., `MODE: LIGHT` \u002F `MODE: DARK`), instant swap, no animation.\n\n### 1.4 Flexbox Layout & Mobile-First\n- Build all layout structures with Flexbox (`display: flex`).\n- Every flex container defaults to `align-items: center` unless a documented exception exists (e.g., intentional misalignment for the brutalist \"broken\" aesthetic — justify each exception in a CSS comment).\n- All layouts must be mobile-responsive: rows collapse to columns on small viewports. **No horizontal scrolling at any breakpoint** — the intentional overlap effects must degrade gracefully on mobile.\n\n### 1.5 Framework Default\nUse plain, hand-written CSS (no Tailwind required for this theme — the raw aesthetic demands full control). Define reusable classes: `.btn`, `.card`, `.input-group`, `.section`, `.container`. One naming convention (BEM or fixed utility set) throughout — never mix.\n\n### 1.6 Typography & Icons\n- **Fonts:** Load **Google Fonts** — use a monospace display font (e.g., `Space Mono` or `IBM Plex Mono`) bound to `--font-base`. Fallback stack: `'Courier New', monospace, system-ui`.\n- **Icons:** Google Material Symbols only. **Inline SVGs and local icon files are forbidden.**\n- Typography rules: `font-weight: 900`, `text-transform: uppercase` on headings and buttons, oversized hero type via `clamp(2rem, 8vw, 10rem)`, tight\u002Fnegative letter-spacing on display text.\n\n---\n\n## 2. BRUTALIST VISUAL DIRECTION (MANDATORY)\n\n- **Raw & stark:** No polish, no gradients, no rounded corners, no blur, no soft shadows.\n- **Borders:** Thick visible borders, `3px–5px solid`, using `--border-default`.\n- **Hard shadows:** `box-shadow: 8px 8px 0 var(--primary)` style only. On hover, shift the shadow offset (e.g., `4px 4px 0`) and translate the element — instant, no transition.\n- **Intentional overlap:** At least one section (e.g., hero headline over a marquee strip, or a testimonial card overlapping the section boundary) uses `mix-blend-mode: difference` or negative margins to create the \"broken\" layout effect. Keep this desktop-scoped or simplified on mobile to avoid overflow.\n- **Visible grid:** Sections separated by full-width horizontal rules (4px solid); optional vertical grid lines via borders on a flex column layout.\n- **Accent usage:** Neon green, hot pink, electric blue, yellow used as loud, sparing accent blocks — highlight words, hover fills, tag labels. Never as subtle gradients.\n- **Anti-design details:** Slightly rotated elements (e.g., `transform: rotate(-1deg)` on a badge), mismatched column widths, oversized raw labels like `[ 01 ]`, `\u002F\u002F\u002F`, `>>>` as section markers.\n\n---\n\n## 3. SECTIONS TO BUILD (IN ORDER)\n\n1. **Header\u002FNav:** Sticky top bar, thick bottom border, monospace logo text, nav links, theme toggle. Mobile: collapse to a simple stacked or bordered menu (no smooth animation — instant show\u002Fhide).\n2. **Hero:** Full-viewport block, `#fefefe` (light) \u002F `#000000` (dark) background, massive `clamp(2rem, 8vw, 10rem)` weight-900 uppercase headline, one accent word in neon green or hot pink, a bordered sub-line, and two CTAs (primary filled black\u002Fwhite, secondary outlined). Include one overlapping element with `mix-blend-mode: difference`.\n3. **Features (3 cards):** Flex row → column on mobile. Each card: thick border, hard shadow, large Google Material Symbol icon, `[ 01 ]`-style index label, uppercase heading, body text. Hover: instant shadow-shift + translate.\n4. **How It Works (3 steps):** Numbered steps with oversized raw numerals (900 weight), connected by visible border lines; alternating black\u002Fwhite blocks for contrast.\n5. **Testimonials:** At least 3 quote blocks; one intentionally rotated or overlapping the section edge. Include names\u002Froles in monospace.\n6. **Pricing (3 tiers):** Middle tier visually emphasized (inverted colors, larger border, \"MOST RAW\" style badge). Each tier: price in oversized type, feature list with Material Symbols check icons, CTA button.\n7. **FAQ:** Use native `\u003Cdetails>`\u002F`\u003Csummary>` elements styled brutally (thick borders, `+`\u002F`−` indicator via Material Symbol, instant open\u002Fclose — no animation).\n8. **Final CTA:** Full-width inverted block (black on light theme, white-on-black text on dark theme) with massive headline and a single loud button.\n9. **Footer:** Thick top border, secondary links in columns, monospace copyright, repeating decorative text strip (e.g., `BRUTAL \u002F\u002F\u002F BRUTAL \u002F\u002F\u002F BRUTAL`).\n\n---\n\n## 4. COMPONENT STATE REQUIREMENTS\n\n### 4.1 Buttons (`.btn`, `.btn-primary`, `.btn-secondary`, `.btn-danger`)\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` min touch target 44×44px, uppercase, weight 900, 3px border, hard shadow.\n- **Hover:** Instant — background inverts (black↔white) or fills with an accent color; shadow offset shrinks; `cursor: pointer`. **No transition property.**\n- **Focus:** Distinct 4px offset outline using `--accent-electric-blue` for keyboard navigation.\n- **Active\u002FPressed:** `transform: translate(4px, 4px)` with shadow removed — instant.\n- **Loading:** Disabled interaction, spinner rendered via a rotating bordered square (CSS-only, `border` + `animation: spin`) or animated Material Symbol; button dimensions must not change.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** Temporary fill using `--text-success` \u002F `--text-error` tokens.\n- **Danger:** `.btn-danger` uses `--accent-bright-red` fill\u002Fborder — visually distinct in both themes.\n\n### 4.2 Cards (`.card`)\n- **Default:** Flexbox, `--bg-secondary`, 4px border, hard shadow.\n- **Hover:** Instant shadow-shift + `translateY(-2px)` (no transition).\n- **Focus-within:** Border color changes to accent when a child link\u002Fbutton has focus.\n- **Skeleton:** Shimmer-free brutalist loading — a blinking (steps-timing, instant toggle) grey block; no layout jump.\n- **Empty State:** Material Symbol icon + guidance text in a bordered block.\n\n### 4.3 Forms (newsletter signup in footer or CTA)\n- Wrap label, input, and error container in a flex `.input-group`.\n- **States:** Empty, focused (4px accent outline ring), filled, valid (neon green border + check icon), invalid (`--border-error`, red text, error Material Symbol), disabled, read-only.\n- Errors announced via an `aria-live=\"polite\"` region.\n\n### 4.4 Modal (FAQ \"contact\" or pricing detail — optional but if included)\n- Opening\u002Fopen\u002Fclosing with **instant** visibility toggles (no fade animations).\n- Centered flex overlay, backdrop solid black at 90% opacity, Material Symbol close button, focus trap, `Esc` and overlay-click close, `role=\"dialog\"` + `aria-modal=\"true\"`.\n\n---\n\n## 5. CORE UX & ACCESSIBILITY RULES\n\n- **Responsive by default:** Fluid `clamp()` typography, breakpoints via flex-wrap and media queries, zero horizontal overflow.\n- **Instant, not absent, feedback:** `transition: none` everywhere, but every hover\u002Fclick\u002Fsubmit must produce a visible state change.\n- **`prefers-reduced-motion`:** Disable the loading spinner animation and any marquee\u002Fblink effects.\n- **Accessibility:** WCAG-sufficient contrast in both themes (neon accents on black pass; never put yellow text on white). Never rely on color alone — pair error states with icons and text. Semantic HTML5 (`\u003Cheader>`, `\u003Cnav>`, `\u003Cmain>`, `\u003Csection>`, `\u003Cfooter>`, `\u003Cdetails>`), logical focus order, full keyboard operability, `aria-live` regions for dynamic feedback.\n- **Destructive actions:** Visually distinct via `.btn-danger` in both themes.\n\n---\n\n## 6. DELIVERABLES & OUTPUT FORMAT\n\n- **Files:** `index.html`, `style.css`, `script.js` — separate files. Only one deferred `\u003Cscript src=\"script.js\">` reference in the HTML; no inline script blocks.\n- **script.js scope:** Theme toggle + `localStorage` persistence, mobile nav toggle, newsletter form validation, FAQ aria enhancements, and button loading-state demo logic only. Nothing more.\n- **Naming:** One consistent convention (BEM recommended: `.card__title`, `.card--featured`) throughout.\n- **Copy:** Write all user-facing copy in **English**. Loud, blunt, anti-marketing brutalist voice (e.g., \"NO GRADIENTS. NO MERCY.\"). No lorem ipsum — write real copy for every section.\n- **Comments:** Brief CSS comments justifying any `align-items` exception and each intentional \"broken\" layout choice.\n\nBuild the complete landing page now, in one attempt, following every rule above.\n",1791954986860]
