Build a complete, production-quality landing page on the first attempt. Follow every rule below exactly. Where a rule and your habit conflict, the rule wins.\n\n---\n\n## 0. PROJECT BRIEF & DESIGN DIRECTION\n\n* **Theme:** \"ENIGMA — rotors & lamps\" — a fictional industrial-grade encryption product styled after the Enigma cipher machine.\n* **Output Category:** Industrial & Mechanical. Copy tone: precise, mechanical, engineering-grade (e.g., \"Encryption, engineered like a machine.\").\n* **Visual Style:** Neumorphism (soft-UI) with subtle gradients. Era: 2020s Digital.\n* **Signature Motif:** The page must visibly celebrate **rotors** (stepping letter dials) and **lamps** (glowing indicator lights). The Hero contains a CSS-built Enigma panel: three neumorphic rotor dials and a lampboard grid of glowing lamps. No images required — build it with HTML\u002FCSS.\n* **Sections (in this order):** Sticky Header\u002FNav → Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ → Final CTA → Footer with secondary links.\n* **Palette Mapping (Light = primary\u002Fdefault theme):**\n  * Backgrounds: `--bg-primary: #e8dcc8` (warm parchment — never pure white), `--bg-secondary: #efe4d2` (raised neumorphic surface), inset\u002Fpressed surface: `#ddd0b8`.\n  * Text: `--text-primary: #1c1610`, `--text-secondary: #5a4530`.\n  * Accents: `--primary: #423322` (opaque accent), `--secondary: #5a4530`, `--accent-deep: #382a1a`.\n  * **Special token:** The spec's `#42332200` is a fully transparent 8-digit hex. Define it as `--primary-glaze: #42332200` and use it only for transparent hover tints\u002Foverlays; use opaque `#423322` wherever solid color is needed.\n  * **Lamp glow:** Derive one warm amber glow token (e.g., `--lamp-glow`) from the secondary family for \"lit\" lamp states; it must read clearly against both themes.\n* **Neumorphism Shadow Formula (mandatory):** Raised elements use dual shadows — a light source top-left, dark bottom-right (Light mode: `box-shadow: 8px 8px 16px var(--shadow-dark), -8px -8px 16px var(--shadow-light)` with `--shadow-light: rgba(254,254,254,0.65)`). Pressed\u002Finset elements invert the formula. Dark mode recalculates both shadows for dark surfaces.\n* **Gradients:** Subtle only — a soft radial wash behind the Hero, a faint conic sheen on rotor dials, and a gentle gradient on the Final CTA banner. No loud rainbow gradients.\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 anywhere in the HTML.\n* **Class\u002FID Selectors Only:** All design properties, layout rules, and states are targeted via class or ID selectors in `style.css`.\n* **Minimal HTML Modifications:** HTML stays clean, semantic, and style-agnostic. Re-theming the site must require editing only the CSS file.\n\n### 1.2 CSS Variables (`var(--...)`) & Theme Tokens\nAll visual tokens live in `:root` (Light) and are overridden under `.dark` and `@media (prefers-color-scheme: dark)`:\n* **Required tokens:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`, `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`, `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`, `--z-dropdown`, `--z-modal`, `--z-toast`.\n* **Additional neumorphism tokens:** `--shadow-light`, `--shadow-dark`, `--neu-shadow-out`, `--neu-shadow-in`, `--primary-glaze`, `--lamp-glow`, `--font-base`, `--font-mono`.\n* **Contrast Pairing:** Every light background token pairs with dark text tokens and every dark background token pairs with light text tokens — enforced in both themes, not just the default.\n* **Light Mode Background:** Never `#ffffff`; the parchment `#e8dcc8` family is the base. Where a near-white is unavoidable, use `#fefefe`.\n* **Success\u002FError tokens:** Choose muted, warm-harmonized green\u002Fred values that pass WCAG AA contrast on both parchment and near-black backgrounds.\n\n### 1.3 Mandatory Dark Mode Support\n* **Exception clause:** The source spec marks Light as the primary theme (✓ Light \u002F ○ Dark). Light is therefore the **default on first visit**, but full Dark Mode support remains mandatory.\n* **Implementation:** Define dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`. Dark palette: `--bg-primary: #120e0a`, `--bg-secondary: #1c1610`, text `#e8dcc8` \u002F muted `#b3a184`, with recalculated neumorphic shadows (near-black dark shadow, faint `rgba(254,254,254,0.04)` light shadow).\n* **Theme Switching:** All variables swap seamlessly with zero HTML restructuring.\n* **Persistence:** Store the user's choice in `localStorage`; fall back to `prefers-color-scheme` on first visit. Header contains a visible toggle (Material sun\u002Fmoon icon) with correct `aria-pressed` and `aria-label` state.\n\n### 1.4 Layout — CSS Grid + Flexbox, Mobile-First\n* **CSS Grid (macro layouts):** page container, Hero two-column split, Features\u002FTestimonials\u002FPricing card rows (`grid-template-columns: repeat(auto-fit, minmax(280px, 1fr))`), the lampboard, and Footer link columns.\n* **Flexbox (components):** nav, buttons, card internals, form groups, step rows.\n* **Default Alignment Rule:** Every flex container defaults to `align-items: center` unless an explicitly justified exception exists (document the exception in a CSS comment).\n* **Mobile-Friendly First:** All grids collapse to single columns on small viewports; rows convert to columns. Zero horizontal scrolling at any width from 320px up.\n\n### 1.5 Framework Default & Tailwind CSS Integration\n* Use Tailwind CSS via CDN (or clean custom CSS driven by `@layer` \u002F `@apply`). All utilities must map back to the CSS variables above or to generic reusable classes (`.btn`, `.card`, `.input-group`, `.nav`, `.accordion__item`).\n* Do not let utility classes hardcode hex values — colors always resolve through `var(--...)`.\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n* **Text:** Load Google Fonts via `\u003Clink>`: **Space Grotesk** (or Archivo) for headings\u002Fbody, bound to `--font-base`; **IBM Plex Mono** bound to `--font-mono` for rotor letters, eyebrow labels, stats, prices, and step numbers.\n* **Icons:** Google Material Symbols only. Raw inline SVGs and local icon files are forbidden.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n### 2.1 Button Component Requirements\nStyle all states via CSS classes (`.btn`, `.btn--primary`, `.btn--secondary`, `.btn--danger`):\n* **Default:** Flex layout (`display: flex; align-items: center; justify-content: center; gap: 0.5rem;`), minimum 44×44px touch target, raised neumorphic surface.\n* **Hover:** Brightness\u002Fshadow shift with `cursor: pointer`.\n* **Focus:** Distinct `:focus-visible` ring built from CSS variables — neumorphic shadows alone never indicate focus.\n* **Active\u002FPressed:** Invert to the inset neumorphic shadow plus `transform: scale(0.97)` — the button must feel physically depressed like a machine key.\n* **Loading:** Disables interaction, prevents double-clicks, renders an animated CSS spinner or spinning Google Icon 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* **`.btn--danger`** must be defined and visually distinct in both themes even if unused on this page.\n\n### 2.2 Card Component Requirements\nApplies to Features, Testimonials, and Pricing cards:\n* **Default:** Grid\u002FFlex layout, neumorphic raised surface using `--bg-secondary`, subtle `--border-default` border (never rely on shadow alone to delineate interactive cards).\n* **Hover:** Elevation shift or `transform: translateY(-2px)`.\n* **Focus-within:** Card border highlights when a child link\u002Fbutton receives focus.\n* **Loading (Skeleton):** Define shimmer keyframes in CSS for reusable skeleton cards.\n* **Empty State:** Define a fallback layout with a Google Icon and guidance text.\n\n### 2.3 Form & Input Requirements\nUsed by the Final CTA email capture:\n* **States:** Empty, Focused (outline ring), Filled, Valid (success border + Material check icon), Invalid (error border, `--text-error` message, error icon), Disabled, Read-only.\n* **Structure:** Flex container wrapping a `\u003Clabel>`, input field (inset neumorphic well), and a dedicated error feedback element with `aria-live=\"polite\"`.\n* **Submission:** Simulate async submit — button enters Loading, then resolves to Success (or Error for invalid email). All feedback announced via `aria-live`.\n\n### 2.4 Modal \u002F Popup Requirements (conditional)\nIf you introduce any overlay (e.g., a \"Watch the Machine\" demo modal), it must implement: Opening\u002FOpen\u002FClosing CSS transitions, centered flex container, backdrop overlay, Google Icon close button, keyboard focus trapping, and close via `Esc` or overlay click. If no modal is in scope, omit it entirely — do not add one speculatively.\n\n### 2.5 Landing Page Section Specifications\n* **Header\u002FNav:** Sticky neumorphic bar. Logo (Material icon + \"ENIGMA\" wordmark), anchor links to all sections, theme toggle, CTA button. Below 768px, collapse to an accessible hamburger (aria-expanded, keyboard operable).\n* **Hero:** Two-column grid. Left: mono eyebrow label, H1, subcopy, dual CTAs (`.btn--primary` \"Start Encrypting\" + `.btn--secondary` \"See How It Works\"), mono stat row. Right: the **Enigma panel** — a large neumorphic enclosure containing (a) three rotor dials: circular inset wells, each with a conic-gradient sheen and a mono letter window; clicking a rotor or pressing ArrowUp\u002FArrowDown steps its letter with a `transform` transition; expose them as buttons with `aria-label` that updates (e.g., \"Rotor I, current setting B\"); and (b) a lampboard: CSS Grid of 26 small lamps labeled A–Z in mono font, a subset \"lit\" with `--lamp-glow` and a slow staggered flicker animation — static under `prefers-reduced-motion`.\n* **Features (3 cards):** Material icon inside an inset neumorphic circle, title, mechanical-toned copy (e.g., rotor-based key derivation, lamp-verified delivery, plugboard-style access control).\n* **How It Works (3 steps):** Numbered `01 \u002F 02 \u002F 03` in mono, connected by a track line (horizontal on desktop, vertical on mobile), each with icon and copy.\n* **Testimonials:** 3 neumorphic cards; avatars are initial letters in inset circles (no external images), quote, name, role, and a small \"verified\" lit-lamp indicator.\n* **Pricing (3 tiers):** Middle tier visually elevated with an inset \"MOST DEPLOYED\" badge. Include a Monthly\u002FAnnual neumorphic segmented toggle (`aria-pressed`, prices update in `--font-mono` with an `aria-live=\"polite\"` announcement). Each tier: name, price, feature list with Material check icons, CTA button.\n* **FAQ:** 5–6 themed questions as an accessible accordion — each item is a `\u003Cbutton aria-expanded aria-controls>` header (rotating Material chevron) plus a region animated via CSS `grid-template-rows` or `max-height` transition. Fully keyboard operable.\n* **Final CTA:** Gradient-sheened neumorphic banner with headline and the email form from 2.3.\n* **Footer:** Grid of secondary link columns (Product, Company, Resources) with realistic English labels, brand block with tagline, Material social icons, and copyright line.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n* **Responsive by Default:** Fluid sizing, breakpoints at ~1024\u002F768\u002F480px, no horizontal overflow anywhere.\n* **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; every hover, click, toggle, and submission produces visible feedback. Respect `prefers-reduced-motion` (disable flicker, rotor spin, and reveal motion).\n* **Accessibility (a11y):** WCAG AA contrast in both themes; never communicate state by color alone (pair color with icons, text, or shape); semantic HTML5 landmarks (`header`, `main`, `section`, `footer`); logical DOM\u002Ffocus order; full keyboard operability; `aria-live` regions for form feedback, pricing toggle, and rotor settings.\n* **Scroll Reveal:** Subtle IntersectionObserver-driven reveal on section entry (translate + fade), disabled under reduced motion.\n* **Destructive Actions:** `.btn--danger` styling must be distinct in both themes.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n* **File Structure:** Separate `index.html`, `style.css`, `script.js`. No inline `\u003Cscript>` blocks beyond one deferred `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` entry point. No inline styles anywhere.\n* **Naming Convention:** Strict BEM (`block__element--modifier`) across HTML and CSS — never mix conventions.\n* **Copy:** Write all user-facing copy in **English**, themed to the ENIGMA product with an Industrial & Mechanical tone. No lorem ipsum; no unrequested placeholders.\n* **Definition of Done:** Light mode renders by default; dark mode toggles and persists; every interactive element (nav, rotors, lamps, toggle, accordion, pricing switch, form, buttons) is keyboard accessible and visually responsive in both themes.\n",1791954982748]
