Code the complete, production-ready landing page on the first attempt. Deliver final code — no drafts, no TODOs, no placeholder stubs.\n\n**Project Brief (source spec translated to English — the entire deliverable must be in English):**\n- **Theme:** \"Network Flow\" style — Robust, Connected, Efficient. Era: 2026+ Ubiquitous Connectivity.\n- **Keywords:** networking, infrastructure, data center, connectivity, security, cloud, robust, efficient, scalable, integrated.\n- **Category:** Corporate & SaaS — landing page for a network\u002Finfrastructure solutions product.\n- **Visual direction:** connectivity-blue accents, dark-grey surfaces, data-flow visualizations, interactive network diagrams, subtle connection glows, robust typography, modular elements, network-traffic animations, efficient and integrated feel.\n- **Theme support:** Full Light + Dark modes — both mandatory.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n- All styling lives in `style.css`. **The `style=\"...\"` attribute is forbidden** — zero inline CSS anywhere in `index.html`.\n- Target every design property, layout rule, and state via class or ID selectors only.\n- HTML stays semantic and style-agnostic: re-theming the page must require editing `style.css` only, never the markup.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine the full token system in `:root`, overridden in `.dark` (and mirrored in `@media (prefers-color-scheme: dark)`). Required baseline:\n\n```css\n:root {\n  --primary: #005691;        \u002F* Connectivity Blue — filled buttons, borders, focus rings *\u002F\n  --primary-accent: #005691; \u002F* links & text accents *\u002F\n  --secondary: #FFA500;      \u002F* Orange — badges, highlights (never small text on light bg) *\u002F\n  --bg-primary: #FEFEFE;\n  --bg-secondary: #F8F8F8;\n  --text-primary: #333333;   \u002F* Dark Grey *\u002F\n  --text-secondary: #595959;\n  --text-success: #0A7D0A;   \u002F* accessible Electric Green for light-mode text *\u002F\n  --text-error: #C62828;\n  --border-default: #CCCCCC;  \u002F* Light Grey *\u002F\n  --border-success: #0A7D0A;\n  --border-error: #C62828;\n  --accent-cyan: #00FFFF;     \u002F* data-flow pulses\u002Fglows — dark surfaces & effects only *\u002F\n  --accent-green: #00FF00;   \u002F* Electric Green — status glows, dark-mode success text *\u002F\n  --surface-dark: #1A1A1A;   \u002F* dark diagram panel, used in both themes *\u002F\n  --radius-sm: 4px; --radius-md: 8px; --radius-lg: 16px;\n  --shadow-sm: 0 2px 5px rgba(0,0,0,0.08);\n  --shadow-md: 0 10px 30px rgba(0,0,0,0.14);\n  --spacing-gap: 1.5rem;\n  --transition-fast: 0.15s; --transition-normal: 0.3s; --ease-standard: ease-in-out;\n  --z-dropdown: 1000; --z-modal: 2000; --z-toast: 3000;\n  --font-base: \"Open Sans\", sans-serif;\n}\n.dark {\n  --primary-accent: #4DA3D9; \u002F* lightened Connectivity Blue for AA links on dark *\u002F\n  --bg-primary: #141414; --bg-secondary: #212121;   \u002F* derived from Black #000000 family *\u002F\n  --text-primary: #FEFEFE; --text-secondary: #CCCCCC;\n  --text-success: #00FF00; --text-error: #FF6B6B;\n  --border-default: #333333; --border-success: #00FF00; --border-error: #FF6B6B;\n  --shadow-sm: 0 2px 5px rgba(0,0,0,0.4); --shadow-md: 0 10px 30px rgba(0,0,0,0.55);\n}\n```\n\n- **Contrast pairing (mandatory in every theme):** light background tokens pair with dark text tokens; dark background tokens pair with light text tokens. Filled primary buttons keep `#005691` background with white text in both themes (7.6:1). Never place `#00FF00`\u002F`#00FFFF` as text on light surfaces — those hues are reserved for glows, pulses, and dark surfaces.\n- **No pure white:** where a white surface is needed, use `#FEFEFE`, never `#FFFFFF`. **Exception clause:** the source spec's `background: #FFFFFF` and `linear-gradient(to bottom, #F8F8F8, #FFFFFF)` are implemented as `#FEFEFE` and `linear-gradient(to bottom, #F8F8F8, #FEFEFE)` per the no-pure-white rule.\n- You may fine-tune token lightness only to preserve WCAG AA contrast; never change hue families.\n\n**1.3 Mandatory Dark Mode Support**\n- Define dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`; theme switching must never require HTML restructuring.\n- Provide a visible header toggle: a button with Material Symbol `dark_mode`\u002F`light_mode`, correct `aria-pressed` state, and `aria-label` (\"Switch to dark theme\" \u002F \"Switch to light theme\").\n- Persist the choice in `localStorage` (e.g., key `networkflow-theme`); on first visit fall back to `prefers-color-scheme`.\n- **Exception clause:** in addition to the single deferred `script.js`, one minimal inline snippet (≤ 5 lines) in `\u003Chead>` is permitted solely to read `localStorage` and apply `.dark` before first paint (prevents a wrong-theme flash). No other inline JS is allowed.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build every layout structure with Flexbox (`display: flex`).\n- **Every flex container defaults to `align-items: center`** unless an exception is explicitly justified in a CSS comment.\n- Mobile-first: multi-column rows collapse to single columns on small viewports; **no horizontal scrolling at any width down to 320px**; all touch targets ≥ 44×44px.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS for layout, spacing, and responsive utilities only. Every themed component (`.btn`, `.card`, `.input-group`, `.accordion`, `.modal`, `.toast`, `.network-diagram-animation`, `.data-flow-effect`) must be a named class defined in `style.css` inside `@layer components` (via `@apply` or plain CSS), mapped to the CSS variables above.\n- Never hardcode hex values where a token exists; never style colors, fonts, borders, or states through arbitrary utility values.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Load **Open Sans** (weights 400, 600, 700, 800) from Google Fonts via `\u003Clink>` with `preconnect`; bind to `--font-base`. Use 700\u002F800 weights for headings to deliver the \"robust typography\" direction.\n- Load **Google Material Symbols (Outlined)** via `\u003Clink>` for every icon.\n- **Inline SVGs, local icon files, and emoji-as-icons are forbidden.** Exception clause: the spec's \"interactive network diagrams\" must be built from CSS (flex\u002Fgrid node layouts, Material Symbol nodes, pseudo-element connector lines, keyframe-animated pulses) — not from SVG.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component (`.btn` + variants `.btn--primary`, `.btn--secondary`, `.btn--ghost`, `.btn--danger`)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px.\n- **Hover:** brightness\u002Fshadow shift with `cursor: pointer` (subtle glow permitted on dark theme).\n- **Focus:** distinct ring via `box-shadow`\u002F`outline` using `--primary` — visible in both themes.\n- **Active\u002FPressed:** `transform: scale(0.97)`.\n- **Loading (`.is-loading`):** disables interaction, prevents double-clicks, renders a CSS spinner (border-based or spinning Material Symbol `progress_activity`) without distorting button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError (`.is-success` \u002F `.is-error`):** temporary feedback using `--text-success` \u002F `--text-error`, never color-only (pair icon + text).\n- `.btn--danger` must be visually distinct in both light and dark themes.\n\n**2.2 Card Component (`.card`)**\n- **Default:** flexbox layout, `--bg-secondary` surface, `1px solid var(--border-default)`, `--radius-md`, `--shadow-sm`.\n- **Hover:** `transform: translateY(-2px)` plus elevation shift.\n- **Focus-within:** card border highlights when a child link\u002Fbutton receives focus.\n- **Loading (skeleton):** `.skeleton` shimmer keyframes defined in CSS, reserving space to prevent layout jumps (used in the modal body and async feedback areas).\n- **Empty state:** `.card--empty` fallback layout with a Google Icon and clear guidance text (used for modal error\u002Fempty results).\n\n**2.3 Form & Input (`.input-group`) — used by the Final CTA email capture**\n- **Structure:** flex container wrapping a `\u003Clabel>`, the input, and a dedicated message container with `aria-live=\"polite\"`.\n- **States via classes:** empty, focused (outline ring), filled, valid (`.is-valid`: success border + `check_circle` icon), invalid (`.is-invalid`: error border, `--text-error` message, `error` icon), disabled, read-only.\n- Never rely on color alone: pair borders with icons and text messages.\n\n**2.4 Modal \u002F Popup (`.modal`) — \"Request a demo\" dialog**\n- **States:** opening, open, loading, success\u002Ferror, closing — all animated via CSS transitions.\n- **UX:** centered flex container (`align-items: center`), backdrop overlay, close button with Material Symbol `close` + `aria-label=\"Close dialog\"`, keyboard focus trapping, close via `Esc` and overlay click, focus returned to the trigger, `role=\"dialog\"`, `aria-modal=\"true\"`, `aria-labelledby`, stacked at `--z-modal`.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, standard breakpoints, zero horizontal overflow.\n- **Smooth animations:** every state change uses `transition: all var(--transition-normal) var(--ease-standard)` (matching the spec's `0.3s ease-in-out`). All network-traffic animations, pulses, and glows must be disabled under `prefers-reduced-motion: reduce`.\n- **Accessibility:** WCAG AA contrast in both modes; never communicate state by color alone; semantic HTML5 landmarks (`header`, `nav`, `main`, `section`, `footer`); correct ARIA roles\u002Flabels on the accordion, modal, theme toggle, and mobile menu; logical DOM\u002Ffocus order; full keyboard operability; a skip-to-content link; `aria-live` regions for form errors, loading, and success feedback.\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Theme micro-interactions:** pulsing status dots (Electric Green \"All systems operational\"), animated data-flow pulses along connector lines (cyan\u002Fgreen), subtle connection glows on hover, hover elevation on cards — all CSS-only.\n- **Toasts:** define `.toast` (stacked at `--z-toast`) for transient confirmations, announced via `aria-live`.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` blocks beyond the single deferred entry point (plus the ≤ 5-line theme bootstrap exception in 1.3).\n- **Naming:** BEM exclusively for components (`.card__title`, `.card--featured`, `.btn--primary`); Tailwind utilities only for layout. Never mix conventions for the same concern.\n- **Copy:** write real, polished English marketing copy for a network-solutions SaaS (uptime SLAs, latency, zero-trust security, edge connectivity, scalability) with a confident, forward-looking 2026 tone. **Lorem ipsum is forbidden.** All user-facing text in English — no Portuguese or Spanish anywhere in the deliverable.\n- No unrequested placeholders; no external raster images — all decorative visuals are CSS + Material Symbols.\n\n---\n\n## 5. PAGE STRUCTURE & SECTION-BY-SECTION REQUIREMENTS\n\n1. **Sticky Header:** logo (Material Symbol `hub` + wordmark), anchor nav (Features, How It Works, Testimonials, Pricing, FAQ), theme toggle, primary CTA. Sticky bar uses `border-bottom: 1px solid var(--border-default)` and `box-shadow: var(--shadow-sm)`. Mobile: hamburger (`menu`\u002F`close` symbols, `aria-expanded`, collapsible flex-column menu).\n2. **Hero:** status pill with pulsing green dot (\"All systems operational\"), H1 in 800 weight, subheadline, dual CTAs (`.btn--primary` \"Start free trial\"; `.btn--secondary` \"See how it works\" → smooth-scroll to How It Works), trust strip (99.99% uptime · \u003C12 ms latency · 40+ edge locations). Light background: `linear-gradient(to bottom, #F8F8F8, #FEFEFE)`. Beside the copy, the **network diagram**: a CSS-built diagram on the `--surface-dark` panel (in both themes), nodes are Material Symbols (`hub`, `router`, `dns`, `cloud`, `storage`, `security`) connected by pseudo-element lines carrying `.data-flow-effect` traveling cyan\u002Fgreen pulses and a `.network-diagram-animation` subtle glow. Nodes are keyboard-focusable with visible focus rings and a status tooltip micro-interaction on focus\u002Fhover.\n3. **Features — 3 `.card`s:** icons `speed` (Performance), `security` (Zero-trust security), `cloud_sync` (Cloud integration). Each card: icon token, robust title, concise copy, hover lift + glow, focus-within highlight. 3-column grid → 1 column on mobile.\n4. **How It Works — 3 modular steps:** 01 Connect (`cable`), 02 Configure (`tune`), 03 Scale (`trending_up`), joined by a connector line with animated flow dots; vertical stack on mobile.\n5. **Testimonials — 3 cards:** quote, avatar (Material Symbol `person` in a Connectivity-Blue circle), name, role\u002Fcompany, star rating via `star` symbols; hover elevation.\n6. **Pricing — 3 tiers:** Starter \u002F Growth \u002F Enterprise. Featured middle tier: `--secondary` orange \"Most popular\" badge (dark text on orange), `--primary` border, elevated shadow. Feature lists use `check_circle` (included) and `cancel` (not included, muted). CTAs: \"Start free\", \"Get started\", \"Contact sales\" (opens the demo modal). Buttons enter `.is-loading` on click.\n7. **FAQ — accessible accordion:** 5–6 real Q&As (SLAs, data security, migration, contracts, support). Each item: `\u003Cbutton aria-expanded>` + panel (`role=\"region\"`), rotating `expand_more` chevron, smooth CSS height transition, full keyboard support.\n8. **Final CTA band:** Connectivity-Blue background with a subtle data-flow animation, headline, the `.input-group` email capture (all 2.3 states, `aria-live` feedback, submit button with loading → success), plus \"or talk to an engineer\" link opening the demo modal.\n9. **Footer with secondary links:** brand column (short description + pulsing status line), link groups (Product, Company, Resources, Legal), contact\u002Fsocial links using Material Symbols (`mail`, `public`, `rss`), copyright line. All links keyboard-focusable with visible focus rings.\n\n---\n\n## 6.
