[{"data":1,"prerenderedAt":4},["ShallowReactive",2],{"prompt-410-Executive-Dashboard":3},"# System Prompt: Build \"Executive Dashboard\" Landing Page (BI\u002FAnalytics Theme)\n\nYou are a Senior Frontend Engineer and Expert UI Designer. Build a complete, production-ready **Landing Page** for an **Executive Dashboard** product (BI\u002FAnalytics, 2020s Modern style) on the first attempt. Follow every rule below exactly.\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 in all HTML.\n- **Class\u002FID Selectors Only:** All styling must target class or ID selectors in `style.css`.\n- **Minimal HTML Modifications:** HTML must remain semantic and style-agnostic; changing the theme must require editing only CSS.\n\n### 1.2 CSS Variables & Theme Tokens\nDefine 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- **Palette Direction:** Professional blue\u002Fgrey\u002Fwhite base; blue accent for KPI highlights; green for positive trends, red for alerts\u002Fnegative trends, grey for neutral. Light mode background must be a soft blue-grey (e.g., `#f4f6fa`), never pure white — use `#fefefe` where near-white is required.\n- **Contrast Pairing:** Every light background token pairs with a dark text token and vice versa, in both themes.\n- **Radius\u002FShadows:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`.\n- **Spacing\u002FTransitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.\n- **Elevation:** `--z-dropdown`, `--z-modal`, `--z-toast`.\n\n### 1.3 Mandatory Dark Mode\n- Define dark tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class.\n- Persist user choice via `localStorage`, falling back to `prefers-color-scheme` on first visit; include a visible toggle with correct `aria-pressed` \u002F `aria-label` state.\n- Dark mode must use deep blue-grey backgrounds with light text — no pure black.\n\n### 1.4 Flexbox Layout & Mobile-First\n- Build all layout structures with Flexbox (Tailwind utilities or `@layer`\u002F`@apply` custom CSS).\n- Every flex container defaults to `align-items: center` (`items-center`) unless explicitly justified otherwise.\n- All rows collapse to columns on small viewports; no horizontal scrolling at any breakpoint.\n\n### 1.5 Framework Default\nUse **Tailwind CSS** (or custom CSS via `@layer`\u002F`@apply`). All utilities must map to CSS variables or reusable classes (`.btn`, `.card`, `.kpi-card`, `.input-group`). One naming convention (BEM or fixed utility set) throughout — never mix.\n\n### 1.6 Typography & Icons\n- **Fonts:** Google Fonts only — use **Inter** for UI text and a numeric-friendly display weight for KPI values; bind via `--font-base`.\n- **Icons:** Google Material Symbols only. **Exception clause:** the source spec requests inline sparkline SVGs — sparklines are the sole permitted inline SVG usage; all other icons must be Google Material Symbols. No local icon files.\n\n---\n\n## 2. REQUIRED SECTIONS & COMPONENT SPECS\n\nBuild these sections in order: **Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ, Final CTA, Footer with secondary links.**\n\n### 2.1 Hero\n- Headline, subheadline, primary CTA button, and a preview strip of 4 KPI mini-cards (large 24–48px metric values, trend arrows, sparklines).\n- KPI values must animate with a **count-up** effect on load; trend arrows animate direction (slide\u002Ffade in pointing up or down).\n\n### 2.2 KPI \u002F Metric Cards (`.kpi-card`)\n- **Default:** Flexbox layout, `--bg-secondary` surface, `--shadow-sm`, status indicator via `border-left` color (green\u002Fyellow\u002Fred traffic-light system), large metric font (24–48px), label, trend delta, inline sparkline SVG.\n- **Hover:** `transform: translateY(-2px)` lift with shadow shift.\n- **Focus-within:** Border highlight when child elements receive focus.\n- **Loading:** Shimmer skeleton animation in CSS (no layout jump).\n- **Empty State:** Google Icon plus guidance text.\n- **Alert State:** Cards flagged as \"concern\" use red border-left with a subtle **pulse animation** (respecting `prefers-reduced-motion`).\n\n### 2.3 Buttons (`.btn`)\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target.\n- **Hover:** brightness\u002Fshadow shift, `cursor: pointer`.\n- **Focus:** distinct focus ring via CSS variables.\n- **Active:** `transform: scale(0.97)`.\n- **Loading:** disabled interactions, CSS spinner or animated Google Icon, no dimension change.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback states using `--text-success` \u002F `--text-error`.\n- `.btn-danger` must be visually distinct in both themes.\n\n### 2.4 Features (3 cards), How It Works (3 steps), Testimonials\n- Feature cards follow `.card` specs (flex layout, subtle borders, hover elevation, focus-within).\n- Steps rendered as a responsive flex row with numbered badges and Google Icons; testimonials as cards with avatar placeholders, quote, and attribution.\n\n### 2.5 Pricing (3 tiers)\n- Three `.card` tiers; middle tier visually elevated (`--shadow-md`, accent border). Each tier: price, feature list with Google Icon checkmarks, CTA button. Responsive column collapse on mobile.\n\n### 2.6 FAQ\n- Accessible accordion using semantic `\u003Cdetails>`\u002F`\u003Csummary>` or ARIA-compliant custom disclosure; animated open\u002Fclose via CSS transitions; keyboard operable.\n\n### 2.7 Final CTA & Footer\n- Full-width CTA band with primary button. Footer: brand, secondary link columns, social icons (Google Material Symbols), copyright.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, no horizontal overflow.\n- **Animations:** all state changes use `transition: var(--transition-normal)`; count-up, pulse, shimmer, and arrow animations must respect `prefers-reduced-motion`.\n- **Accessibility:** WCAG-sufficient contrast in both themes; never rely on color alone (pair traffic-light indicators with icons\u002Ftext labels like \"Up 12%\" or \"At risk\"); semantic HTML5; ARIA roles\u002Flabels on custom widgets; logical focus order; full keyboard operability; `aria-live` regions for dynamic feedback (form errors, toasts, loading).\n- **Visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Copy:** all user-facing copy in English. Write realistic executive-BI copy (KPIs like \"Revenue\", \"Churn\", \"NPS\", \"Pipeline\") — no lorem ipsum.\n\n---\n\n## 4. DELIVERABLES\n\n- **Files:** separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` blocks beyond one deferred entry-point reference.\n- **Naming:** one consistent convention across all files.\n- **Placeholders:** only where content was genuinely unspecified.\n- **JS scope:** theme toggle with localStorage, count-up animation, accordion behavior, button loading-state demo, and scroll-reveal only. No frameworks; vanilla JS.\n",1791954986442]
