Build the complete, production-ready landing page described below in a single first attempt. Every rule in this document is mandatory. Do not ask clarifying questions; make reasonable decisions only where this spec grants explicit latitude.\n\n---\n\n## 0. DESIGN BRIEF & THEME DIRECTION\n\n**Style Name:** ESCAPEMENT — clockwork mechanism\n**Type:** Time\u002FClock · **Era:** 2020s Contemporary\n**Keywords:** clockwork, escapement, time, clock, animated, gradient\n\n**Aesthetic Direction:** The interior of a fine mechanical watch, rendered with modern restraint — brass gears, espresso-toned depth, warm parchment surfaces, gold light. Precise, rhythmic, and tactile: elements should feel like they tick, wind, and release. Ornament is geometric (dials, tick marks, gear motifs), never skeuomorphic clutter. Layout is clean, grid-driven, and generously spaced — 2020s contemporary, not steampunk costume.\n\n**Brand Narrative (choose one and stay consistent):** \"Escapement\" is a precision time-management platform whose identity borrows from mechanical watchmaking (recommended, fits pricing\u002Ftestimonials\u002FFAQ), OR a bespoke mechanical watch atelier. All user-facing copy must be original, thematic English (e.g., headline seeds: \"Every second, engineered.\" \u002F \"Time, mastered tick by tick.\"). No lorem ipsum anywhere.\n\n**Source Color Palette:**\n- `#241610` espresso · `#120a06` near-black umber · `#d8c9a8` cream parchment\n- `#d4b46a` brass gold · `#8a7454` bronze · `#2e1a22` dark plum (danger foundation)\n\n**Visual Effects (required):** Gradients (brass sheens, radial \"light through gears\" washes, gradient-clipped headline text) and Hover Effects (gear-tick rotations, elevation lift, sheen sweeps).\n**CSS Techniques (required):** Flexbox, Transitions, Transforms, Gradients, Box Shadows, Border Radius, `aspect-ratio`.\n\n**Sections to build, in order:** Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ → Final CTA → Footer with secondary links. A sticky navigation bar is required as global chrome (it hosts the mandatory theme toggle and primary CTA).\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n### 1.1 CSS-First Architecture & Zero Inline CSS\n\n- **No Inline CSS:** The `style=\"...\"` attribute is forbidden anywhere in the HTML. Zero exceptions.\n- **Class\u002FID Selectors Only:** All colors, layout, gradients, states, and animations must be targeted exclusively via class or ID selectors in `style.css`.\n- **Minimal HTML Modifications:** HTML must remain semantic and styling-agnostic — changing the entire visual theme must require edits to `style.css` only, never markup changes.\n\n### 1.2 CSS Variables (`var(--...)`) & Theme Tokens\n\nAll visual tokens must live in `:root` (light mode) and be re-mapped under the dark mode scope (§1.3):\n\n- **Colors (Light Mode defaults):**\n  - `--primary: #d4b46a` (brass — CTAs, accents, focus rings)\n  - `--secondary: #8a7454` (bronze — secondary accents, borders)\n  - `--bg-primary`: a lightened cream wash derived from `#d8c9a8` (e.g., toward `#efe6d2`). Never `#ffffff`.\n  - `--bg-secondary: #fefefe` (elevated card\u002Fsurface color — `#fefefe` is the only near-white permitted)\n  - `--text-primary: #241610` (espresso) · `--text-secondary:` a bronze derived from `#8a7454`, darkened as needed (e.g., toward `#75603f`) to pass WCAG AA on cream surfaces\n  - `--text-success`: a muted patina\u002Fverdigris green harmonized with the brass palette · `--text-error`: a wine-crimson derived from `#2e1a22` (e.g., `#b34258` family) — both AA-compliant in both modes\n  - `--border-default: rgba(36, 22, 16, 0.18)` · `--border-success` and `--border-error` matching their text tokens\n- **Contrast Pairing (mandatory, both themes):** Every light background token pairs with a dark text token; every dark background token pairs with a light text token. `#d4b46a` buttons must use espresso (`#241610`) text.\n- **Gradient Tokens:** Define `--gradient-brass: linear-gradient(135deg, #d4b46a, #8a7454)`, `--gradient-hero` (layered radial brass-glow + umber vignette), and `--gradient-text` (headline clip gradient) as variables so both themes can remap them.\n- **Shape & Depth:** `--radius-sm: 6px`, `--radius-md: 14px`, `--radius-lg: 24px`; `--shadow-sm`, `--shadow-md` (warm umber-tinted, e.g., `rgba(18,10,6,...)` — never flat pure black).\n- **Spacing & Motion:** `--spacing-gap: 1.5rem` (scale section rhythm with `clamp()`); `--transition-fast: 150ms`, `--transition-normal: 300ms`, `--ease-standard: cubic-bezier(0.4, 0, 0.2, 1)`; you may add `--ease-spring: cubic-bezier(0.34, 1.56, 0.64, 1)` for tactile \"tick\" feedback only.\n- **Elevation:** `--z-dropdown: 100`, `--z-modal: 400`, `--z-toast: 500`. No component may use raw z-index values.\n\n### 1.3 Mandatory Dark Mode Support\n\n- **Implementation:** Re-map every token under both a `.dark` class on `\u003Chtml>` (JS-toggled) and `@media (prefers-color-scheme: dark)` as the no-JS\u002Fno-preference fallback. Suggested dark palette: `--bg-primary: #120a06`, `--bg-secondary: #241610`, `--text-primary: #d8c9a8`, `--text-secondary:` lightened bronze (e.g., `#c4ab85` family) for AA, `--primary: #d4b46a`, `--border-default: rgba(216, 201, 168, 0.18)`.\n- **Exception Clause:** The source style designates Light as the flagship mode — default the showcase to Light styling, but Dark Mode is still mandatory and must ship fully designed with the same warm umber\u002Fbrass mood (no neutral grays), never an afterthought.\n- **Theme Switching:** Switching must only re-map variables — no HTML restructuring.\n- **Persistence:** Persist the user's choice in `localStorage`; on first visit fall back to `prefers-color-scheme`. A visible toggle control (sun\u002Fmoon Material icons, swapped via CSS) must carry correct `aria-pressed` and `aria-label` (\"Toggle dark mode\").\n\n### 1.4 Flexbox Layout & Mobile-First Alignment\n\n- **Default Alignment Rule:** Every flex container must default to `align-items: center` (`items-center` in Tailwind) unless an exception is explicitly justified in a CSS comment — e.g., text blocks inside cards may use `flex-start` for readability; state the reason inline.\n- **Mobile-Friendly First:** Author all layouts mobile-first: flex rows must convert to `flex-direction: column` on small viewports; use `clamp()` for type, spacing, and dial sizing. Horizontal scrolling is forbidden at every viewport width down to 320px.\n\n### 1.5 Framework Default & Tailwind CSS Integration\n\n- Use Tailwind CSS (Play CDN acceptable) or clean custom CSS organized with Tailwind's `@layer` \u002F `@apply` directives. All utility usage must map back to the CSS variables above and to generic reusable classes (`.btn`, `.card`, `.input-group`) — no one-off magic values scattered through markup.\n\n### 1.6 Typography & Icons (Google Fonts Mandatory)\n\n- **Text:** Load from Google Fonts via `\u003Clink>` (with `preconnect`) and bind to tokens: `--font-display: 'Fraunces', serif` (headings — alternative: Cormorant Garamond), `--font-base: 'Inter', sans-serif` (body), `--font-mono: 'Space Mono', monospace` (numerals, prices, step counters, eyebrows — the \"engraved dial label\" voice).\n- **Icons:** Google Material Symbols (Rounded) only. Render via `\u003Cspan class=\"material-symbols-rounded\">icon_name\u003C\u002Fspan>`. Raw inline SVGs and local icon files are explicitly forbidden. Use thematic glyphs: `settings` (gears), `schedule`, `timelapse`, `precision_manufacturing`, `autorenew`, `history`, `check`, `close`, `format_quote`, `progress_activity`.\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n### 2.1 Button Component Requirements\n\n- **Base `.btn`:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px (icon-only buttons included), font-weight 600, `transition: var(--transition-fast)`.\n- **Hover:** brightness\u002Fgradient shift plus `--shadow-md` lift; `cursor: pointer`.\n- **Focus:** Distinct `:focus-visible` ring built from CSS variables (`box-shadow: 0 0 0 3px` brass ring or 2px `outline` with offset) — keyboard navigation must be obvious on every button.\n- **Active\u002FPressed:** `transform: scale(0.97)` click feedback.\n- **Loading (`.btn--loading`):** `pointer-events: none` to block double-clicks; swap the leading icon for `progress_activity` with a CSS rotation animation, reserving identical dimensions so the button never shifts; set `aria-busy=\"true\"`.\n- **Disabled:** `opacity: 0.5`, `filter: grayscale(0.6)`, `cursor: not-allowed`, no hover\u002Factive transforms.\n- **Success\u002FError:** `.btn--success` \u002F `.btn--error` temporary states driven by `--text-success` \u002F `--text-error` (e.g., submit → brief check-icon confirmation → revert).\n- **Variants:** `.btn--primary` (brass gradient, espresso text), `.btn--secondary` (transparent, bronze border, `--text-primary` label), `.btn--danger` (plum\u002Fwine derived from `#2e1a22`, visually distinct in both themes).\n\n### 2.2 Card Component Requirements\n\n- **Default `.card`:** Flexbox layout, `--bg-secondary` fill, 1px `--border-default`, `--radius-md`, `--shadow-sm`; interactive cards may stretch to equal heights via flex.\n- **Hover:** `transform: translateY(-2px)` plus shadow elevation shift; decorative gear-icon chips rotate 15–30deg with `--transition-normal` (the mechanical \"tick\").\n- **Focus-within:** Card border shifts to `--primary` when any child link\u002Fbutton receives focus.\n- **Loading (Skeleton):** `.card--skeleton` shimmer animation (sweeping gradient) defined in CSS, matching final dimensions to prevent layout jumps; static under reduced motion.\n- **Empty State:** `.card--empty` fallback: Material icon (e.g., `hourglass_empty`) + clear guidance text.\n\n### 2.3 Form & Input Requirements\n\n- **Structure `.input-group`:** Flex container wrapping a `\u003Clabel for=\"...\">`, the input, and a dedicated error feedback container `\u003Cp class=\"input-error\" aria-live=\"polite\">`.\n- **States:** Empty · Focused (brass ring) · Filled · Valid (`--border-success` + check icon) · Invalid (`--border-error`, error-colored text, `error` icon, message text — never color alone) · Disabled · Read-only. The Final CTA email capture and the modal's form must exercise these states.\n\n### 2.4 Modal \u002F Popup Requirements\n\n- **States:** Opening (fade + scale from 0.96) · Open · Loading · Success\u002FError · Closing — all animated via CSS transitions on classes.\n- **UX Features:** Backdrop overlay (umber-tinted, `rgba(18,10,6,0.6)`), centered flex container (`align-items: center; justify-content: center`), Material icon (`close`) close button at 44×44px, `role=\"dialog\"` + `aria-modal=\"true\"` + `aria-labelledby`, keyboard focus trapping, focus returned to the trigger on close, closable via `Esc` and overlay click, layered at `--z-modal`. Use it for \"View plan details\" from Pricing tiers.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by Default:** Fluid sizing and breakpoints with zero horizontal overflow at any width.\n- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; every animation (gear rotations, shimmer, dial hands, reveals) must be disabled or made static under `prefers-reduced-motion` while preserving state visibility through opacity\u002Fcolor.\n- **Accessibility (a11y):** WCAG AA contrast in both Light and Dark modes; never rely on color alone to communicate state; semantic HTML5 landmarks (`header`, `nav`, `main`, `section` with `aria-labelledby`, `footer`); correct ARIA on custom widgets (accordion: `aria-expanded`\u002F`aria-controls`; toggle: `aria-pressed`; modal: dialog semantics; pricing toggle: `aria-pressed` with accessible price updates); logical DOM\u002Ffocus order; full keyboard operability; visible focus everywhere; `aria-live` regions for form errors, toasts, and loading feedback; include a skip-to-content link.\n- **Mandatory Visual Feedback:** Every click, hover, and submission triggers a visible state change.\n- **Destructive\u002FDistinct Actions:** `.btn--danger` must be visually distinct in both themes.\n- **Theme Micro-Interactions:** Hero dial hands tick with `steps(60)` timing (true escapement feel); gradient headline uses `background-clip: text` with a solid-color fallback; all decorative gear clusters rotate slowly and pause under reduced motion.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File Structure:** Exactly three files — `index.html`, `style.css`, `script.js`. No inline styles; no inline scripts beyond one `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>`.\n- **Naming Convention:** BEM only, everywhere (e.g., `.hero__title`, `.pricing-card__price`, `.faq-item--open`). Never mix conventions.\n- **No Unrequested Placeholders:** The user supplied no copy — therefore write complete, original, thematic English copy for every section. Lorem ipsum is prohibited. No TODOs, no truncated code; ship a finished page.\n\n---\n\n## 5. PAGE ANATOMY — SECTION-BY-SECTION BUILD SPEC\n\n- **Global Chrome:** Skip link; sticky nav (brand gear-icon + \"ESCAPEMENT\" wordmark in display font; anchor links to Features \u002F How It Works \u002F Pricing \u002F FAQ; theme toggle; `.btn--primary` \"Get started\"). Mobile: links collapse into a button-controlled dropdown panel (`--z-dropdown`, `aria-expanded`).\n- **5.1 Hero:** Two-column flex (row on desktop, column on mobile). Left: mono-font eyebrow, gradient-clipped H1, subcopy, dual CTAs (`.btn--primary` + `.btn--secondary` anchor). Right: a pure-CSS timepiece — dial with `aspect-ratio: 1`, `repeating-conic-gradient` tick marks, hour\u002Fminute\u002Fsecond hands as rotated divs (`transform-origin: bottom`) with continuous and `steps(60)` keyframe animations, decorative rotating `settings` gear icons, all over `--gradient-hero`. Static at a \"10:08\" pose under reduced motion.\n- **5.2 Features (3 cards):** Centered section header; 3 `.card`s (icon chip on `--gradient-brass`, display-font title, copy, \"Learn more\" link) in a wrapping flex row → column. Exercise card hover\u002Ffocus-within states.\n- **5.3 How It Works (3 steps):** Semantic `\u003Col>`; steps numbered 01\u002F02\u002F03 in mono; a gradient \"gear train\" connector line (horizontal on desktop, vertical rail on mobile); hover ticks each step's icon.\n- **5.4 Testimonials (3 cards):** `format_quote` icon, quote, brass-gradient monogram avatar circle, name + role; hover elevation; middle card may be subtly emphasized.\n- **5.5 Pricing (3 tiers):** Names: Pendulum \u002F Escapement \u002F Tourbillon. Featured middle tier: gradient border, \"Most popular\" badge, emphasized scale. Monthly\u002Fannual segmented toggle (`aria-pressed`, animated mono-numeral prices, accessible updates). Each tier: feature list with `check`\u002F`close` icons (icon + text, never color alone), CTA opening the plan-details Modal (§2.4) with loading → success\u002Ferror flow.\n- **5.6 FAQ:** 5–6 accordion items — `\u003Cbutton aria-expanded aria-controls>` + panel animated via CSS (`grid-template-rows: 0fr → 1fr`), plus\u002Fadd icon rotating 45deg on open; keyboard operable.\n- **5.7 Final CTA:** Full-width brass-gradient panel (espresso text, AA-verified) with headline, copy, and inline email `.input-group` + submit demonstrating loading → `.btn--success` + inline `aria-live` confirmation + toast.\n- **5.8 Footer with secondary links:** Flex columns — brand + tagline; link columns (Product: Features\u002FPricing\u002FFAQ; Company: About\u002FCareers\u002FPress; Support: Help\u002FContact\u002FStatus); bottom bar with secondary links (Privacy, Terms, Cookies), social links (text links or generic Material icons — no brand logos available in Material Symbols), and a JS-injected current-year copyright. Stacks on mobile.\n- **5.9 Toast Component:** Fixed bottom-right, `--z-toast`, `role=\"status\"` \u002F `aria-live=\"polite\"`, success\u002Ferror variants with Material icons, auto-dismiss transition, reduced-motion safe.\n- **5.10 script.js responsibilities:** Theme init\u002Ftoggle\u002Fpersistence (§1.3); mobile nav toggle; accordion; pricing billing toggle; modal open\u002Fclose\u002Ffocus-trap\u002FEsc; email validation + simulated submit; toast; year injection. Optional scroll-reveal only if content is fully visible without JavaScript and it respects reduced motion.\n\n---\n\n## 6.
