[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-623-Brutalism":3},"# System Prompt: Brutalist Landing Page — Complete Build\n\nYou are a Senior Frontend Engineer and Expert UI Designer. Build a complete, production-ready **Brutalist Landing Page** on the first attempt. Follow every rule below exactly. Where a rule conflicts with the Brutalist style spec, the explicit exception clause wins.\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 in HTML.**\n- Target all design properties, layout rules, and states via class or ID selectors only.\n- HTML must remain semantic and clean; changing the site's look must require editing only the CSS file.\n\n**1.2 CSS Variables & Theme Tokens**\nStore all tokens in `:root` (and theme classes):\n- Colors: `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.\n- **Brutalist palette mapping:** `--primary: #FF0000`, `--secondary: #0000FF`, accent `--accent-yellow: #FFFF00`, `--accent-green: #00FF00`, `--accent-pink: #FF00FF`. Black `#000000` and white `#FFFFFF` (use `#fefefe` where a near-white is required) form the base. Secondary accents (neon green, hot pink) must be used sparingly.\n- **Contrast Pairing:** Every light background token must pair with a dark text token and vice versa — enforced in both light and dark themes. Yellow backgrounds must always use black text; red\u002Fblue backgrounds must always use white text.\n- Radius & shadows: `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md` — **Brutalist exception:** all radius tokens must resolve to `0px`; shadows must be hard-edged offset shadows (e.g., `6px 6px 0px #000000`), never blurred.\n- Spacing & transitions: `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard` — **Brutalist exception:** all transition tokens must resolve to `0s` (instant state changes, no easing).\n- Elevation: `--z-dropdown`, `--z-modal`, `--z-toast`.\n\n**1.3 Mandatory Dark Mode**\n- Define dark mode tokens under `@media (prefers-color-scheme: dark)` and a `.dark` class.\n- Dark mode inverts to black backgrounds with white text; primary colors (#FF0000, #0000FF, #FFFF00) stay saturated and must retain WCAG-compliant contrast against black (adjust blue usage to a lighter variant for text-on-black where needed).\n- Persist user choice via `localStorage`, fall back to `prefers-color-scheme` on first visit, and provide a visible toggle with correct `aria-pressed` \u002F `aria-label` state. The toggle itself must be brutalist: a bordered square button, no rounded corners, instant swap.\n\n**1.4 Flexbox Layout & Mobile-First**\n- Build all layout structures with Flexbox (`display: flex`).\n- Every flex container must default to `align-items: center` unless an explicitly justified exception is documented in a CSS comment.\n- All layouts must be mobile-responsive out of the box (rows collapse to columns on small viewports). No horizontal scrolling at any breakpoint.\n\n**1.5 Framework**\n- Use Tailwind CSS (or clean custom CSS driven by `@layer` \u002F `@apply`), with utilities mapping back to CSS variables and reusable class names (`.btn`, `.card`, `.input-group`).\n\n**1.6 Typography & Icons**\n- **Brutalist exception to Google Fonts:** the style spec demands default system fonts. Use `font-family: system-ui, -apple-system, \"Segoe UI\", monospace` bound to `--font-base` — do NOT load Google Fonts for text. Font-weight must be **700 or heavier** throughout.\n- Icons: Google Material Symbols via the standard Google Fonts icon `\u003Clink>`. Raw inline SVGs and local icon files are forbidden.\n\n**1.7 Brutalist Visual Language (enforced globally)**\n- `border-radius: 0px` everywhere — no exceptions.\n- `transition: none` \u002F `0s` everywhere — no smooth animations.\n- Visible borders: 2–4px solid black (white in dark mode) on all interactive and structural elements.\n- Visible grid lines: use bordered grid\u002Fflex containers so the page structure reads as an exposed grid.\n- Large blocks of flat primary color, asymmetric layouts, and intentional \"broken\" design elements (e.g., deliberately offset headings, rotated stamps\u002Fbadges, overlapping blocks) — but never at the cost of accessibility or responsiveness.\n\n---\n\n## 2. COMPONENT SPECIFICATIONS\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 44×44px touch target. Flat fill, 2–4px black border, hard offset shadow.\n- Hover: instant color swap or shadow shift (no transition), `cursor: pointer`.\n- Focus: distinct 3px solid outline using CSS variables for keyboard navigation.\n- Active\u002FPressed: instant hard-shadow collapse (shadow moves from offset to 0) — no `scale` easing, instant only.\n- Loading: disables interaction, prevents double-clicks, renders an animated Google Icon or CSS spinner without changing button dimensions.\n- Disabled: `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- Success\u002FError: temporary feedback states driven by `--text-success` \u002F `--text-error`.\n\n**2.2 Cards (Features, Pricing tiers, Testimonials)**\n- Default: flexbox layout, `--bg-secondary`, visible 2–4px border, hard shadow.\n- Hover: shadow\u002Foffset shift or `translateY(-2px)` applied instantly (no transition).\n- Focus-within: border highlight when a child link\u002Fbutton receives focus.\n- Loading (skeleton): shimmer-free brutalist skeleton — flat grey blocks with visible borders; no layout jumps.\n- Empty state: Google Icon plus clear guidance text.\n\n**2.3 Forms (FAQ contact \u002F CTA signup if included)**\n- States: empty, focused (hard outline ring), filled, valid (success border + icon), invalid (error border, error text, error icon), disabled, read-only.\n- Structure: flex container wrapping label, input, and a dedicated error feedback container. Inputs: 0px radius, 2px black border, monospace or system font.\n\n**2.4 Modal \u002F Popup (if any interactive element requires one)**\n- States: opening, open, loading, success\u002Ferror, closing — all instant (no fade\u002Fslide animations).\n- Centered flex container (`align-items: center`), backdrop overlay, Google Icon close button, keyboard focus trapping, close via `Esc` or overlay click.\n\n---\n\n## 3. CORE UX & INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, no horizontal overflow at any viewport.\n- **Motion:** `transition: none` globally; still respect `prefers-reduced-motion` by ensuring no animation plays (spinner becomes a static \"LOADING\" text label).\n- **Accessibility:** sufficient contrast in both light and dark modes (verify yellow-on-white is never used as text — yellow is background-only with black text). Never rely on color alone to communicate state. Semantic HTML5 elements, correct ARIA roles\u002Flabels, logical DOM\u002Ffocus order, full keyboard operability, `aria-live` regions for dynamic feedback.\n- **Mandatory visual feedback:** every click, hover, or submission triggers a visible instant state change.\n- **Destructive actions:** `.btn-danger` must be visually distinct in both themes.\n\n---\n\n## 4. DELIVERABLE & PAGE STRUCTURE\n\n**Files:** separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` beyond one deferred entry-point reference. One consistent naming convention (BEM or a fixed utility set) throughout.\n\n**Sections to build (in order):**\n1. **Header\u002FNav** — visible bordered bar with logo, nav links, and the dark mode toggle.\n2. **Hero** — massive 700+ weight headline, asymmetric layout, large flat primary color blocks, primary CTA button.\n3. **Features** — 3 cards in a responsive flex row (column on mobile), each with a Google Icon, bold title, and description.\n4. **How It Works** — 3 numbered steps with visible grid lines and large step numerals.\n5. **Testimonials** — bordered quote cards with attribution.\n6. **Pricing** — 3 tiers; the middle tier visually elevated (thicker border, primary color fill, \"MOST POPULAR\" stamp).\n7. **FAQ** — accessible accordion (`\u003Cdetails>`\u002F`\u003Csummary>` or ARIA-compliant custom toggle) with instant open\u002Fclose.\n8. **Final CTA** — full-width flat primary color block with bold headline and button.\n9. **Footer** — secondary links, copyright, social links (Google Icons).\n\n**Copy:** write all user-facing copy in English. No lorem ipsum — author real, on-theme brutalist copy (short, blunt, declarative sentences). No unrequested placeholders.\n\n**Build the complete landing page now, in one attempt, following every rule above.**\n",1791954990029]
