## 1. STRICT ARCHITECTURE RULES

**1.1 CSS-First & Zero Inline CSS**
- All styling lives in a dedicated `style.css`. **Forbidden:** the `style="..."` attribute anywhere in HTML.
- All design properties, layout rules, and states must be targeted via class or ID selectors only.
- HTML must remain semantic and styling-agnostic: changing the theme requires editing only `style.css`.

**1.2 CSS Variables & Theme Tokens**
Define all tokens in `:root` using the corporate blue palette:

- **Colors:** `--primary: #1E40AF`, `--secondary: #3B82F6`, `--bg-primary: #F8FAFC`, `--bg-secondary: #FFFFFF`, `--text-primary: #0F172A`, `--text-secondary: #334155`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.
- **Accent tokens:** `--navy: #0F172A`, `--blue: #3B82F6`, `--blue-light: #60A5FA`.
- **Shape & depth:** `--radius-sm: 8px`, `--radius-md: 12px`, `--radius-lg: 20px`, `--shadow-sm`, `--shadow-md: 0 4px 20px rgba(0,0,0,0.15)`.
- **Motion & spacing:** `--spacing-gap`, `--transition-fast: 150ms`, `--transition-normal: 300ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`.
- **Stacking:** `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.

**1.3 Dark Mode (Mandatory)**
- Define dark tokens under `@media (prefers-color-scheme: dark)` **and** a `.dark` class on `<html>`.
- Dark palette: navy backgrounds (`#0F172A`), light text (`#F8FAFC`), keeping the blue accent family. Pair every light background token with dark text and vice versa.
- Theme toggle button in the header with correct `aria-pressed` and `aria-label` ("Toggle dark mode"). Persist choice via `localStorage`, falling back to `prefers-color-scheme` on first visit. Switching must not require HTML restructuring.

**1.4 Flexbox Layout & Mobile-First**
- Build every layout with Flexbox. Every flex container defaults to `align-items: center` unless a justified exception exists (e.g., feature card content stacking — document the exception in a CSS comment).
- Mobile-first: rows convert to columns on small viewports (3-card grids → 1 column, then 3 columns ≥ 768px). No horizontal scrolling at any width.

**1.5 Framework**
- Use Tailwind CSS (CDN or build) with utility classes mapped to the CSS variables above, or clean custom CSS with generic reusable classes (`.btn`, `.card`, `.section`, `.pricing-tier`). One consistent naming convention throughout — never mix conventions.

**1.6 Typography & Icons (Google Fonts Mandatory)**
- Load **Inter** from Google Fonts via `<link>`, bound to `--font-base: 'Inter', sans-serif`.
- Icons: **Google Material Symbols** only. **Forbidden:** raw inline SVGs or local icon files.

## 2. VISUAL STYLE & EFFECTS

- **Glassmorphism cards:** metric/pricing/testimonial cards use `backdrop-filter: blur(12px)`, semi-transparent white background, `border-radius: 12px`, `1px solid` translucent border, `box-shadow: 0 4px 20px rgba(0,0,0,0.15)`.
- **Hero background:** `linear-gradient(135deg, #0F172A, #1E40AF)` with subtle decorative blurred blue orbs (`#3B82F6` at low opacity) behind glass cards.
- **Hero metrics cards:** 3–4 small glass cards showing animated counters (e.g., "2.4B events processed", "99.99% uptime", "450+ integrations").
- **Counter animation (JS):** numbers count up on scroll into view using `IntersectionObserver`; respect `prefers-reduced-motion` (render final value immediately).
- **Scroll reveal:** fade/slide-up on sections entering viewport via `IntersectionObserver` + CSS classes (`.reveal`, `.reveal--visible`), disabled under `prefers-reduced-motion`.
- **Hover:** cards lift with soft shadow shift + `transform: translateY(-2px)`; CTAs get a subtle blue glow (`box-shadow: 0 0 24px rgba(59,130,246,0.45)`).
- **All transitions:** `transition: var(--transition-normal) var(--ease-standard)`.

## 3. SECTION SPECIFICATIONS

**Hero:** Two-column flex (headline + subcopy + dual CTA buttons left; mock analytics glass card with animated counters and a simple CSS bar chart right). Headline example: "Turn enterprise data into decisions." Trust strip below (logos as text labels).

**Features (3 cards):** `.card` glass cards with Material Symbol icon, title, description. Topics: Real-time dashboards, 450+ integrations, Enterprise security. Include hover lift and `:focus-within` border highlight.

**How It Works (3 steps):** Numbered horizontal steps (vertical on mobile) with connector line, icon + short copy each.

**Testimonials:** 3 glass cards with quote, name, role, company. Star rating via Material Symbols.

**Pricing (3 tiers):** Starter / Growth (highlighted, "Most popular" badge) / Enterprise. Each tier: price, feature list (check icons), CTA button. Highlighted tier uses `--primary` background with light text (contrast-paired).

**FAQ:** `<details>`/`<summary>` accordion (native, keyboard-accessible) styled via CSS — no JS needed. 5–6 realistic questions.

**Final CTA:** Full-width navy gradient band, headline + single glowing CTA button.

**Footer:** Dark navy background, secondary link columns (Product, Company, Resources, Legal), copyright line. Links get visible focus rings.

## 4. COMPONENT STATES (CSS classes only)

- **Buttons:** Default flex (`display:flex; align-items:center; justify-content:center; gap:0.5rem`), min 44×44px. Hover: brightness/shadow shift. Focus: distinct ring via `--secondary`. Active: `transform: scale(0.97)`. Disabled: `opacity: 0.5; cursor: not-allowed`. Primary CTA variant `.btn-primary` (blue, glow on hover), secondary `.btn-outline`.
- **FAQ summary:** hover background shift, open state rotates chevron icon, focus-visible ring.

---

## 5. UX & ACCESSIBILITY (MANDATORY)

- Semantic HTML5 (`<header>`, `<main>`, `<section>`, `<footer>`, `<nav>`, `<h1>`–`<h3>` hierarchy).
- Full keyboard operability; logical focus order; visible focus styles everywhere.
- Sufficient contrast in **both** light and dark themes (WCAG AA).
- Never rely on color alone to communicate state.
- `aria-live="polite"` region for counter/feedback announcements where relevant.
- All animations respect `prefers-reduced-motion`.
- Every click/hover triggers visible feedback.

## 6. DELIVERABLE

- **Files:** `index.html`, `style.css`, `script.js` (theme toggle, counters, scroll reveal, FAQ needs none). No inline `<script>` blocks beyond one deferred `script.js` reference.
- **Copy:** All user-facing copy in **English**, realistic B2B SaaS content — no lorem ipsum.
- **No unrequested placeholders.** Deliver the complete page in one response.
