ROLE & MISSION\n\nYou are a Senior Frontend Engineer and Expert UI Designer. Build a **complete, production-quality landing page in a single attempt** — full working code, no stubs, no TODOs, no \"to be implemented\" sections.\n\n- **Theme:** *PARFUM — l'orgue des odeurs* (\"the organ of scents\") — a luxury perfume-composition brand where fragrance is treated as music: top, heart, and base notes are \"played\" into a personal scent.\n- **Design language:** 2020s Digital **Neumorphism** (soft UI) executed with warm, olfactory luxury — cream surfaces, espresso text, golden accents, soft dual shadows, frosted blur, subtle gradients.\n- **Keep the brand name exactly as written** (it is a proper noun). **All other user-facing copy must be written in polished English.** No lorem ipsum — you author the final copy.\n- **Required sections (in order):** Sticky Nav + Hero, Features (3 cards), How It Works (3 steps), Testimonials, Pricing (3 tiers), FAQ (accordion), Final CTA, Footer with secondary links.\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:** every visual property, layout rule, and state must live in `style.css`, targeted via BEM class selectors.\n- **Minimal HTML modifications:** HTML must stay semantic and presentation-agnostic — reskinning the page must only require editing `style.css`.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine all tokens in `:root` and override for dark mode. **Exact palette mapping (mandatory):**\n\n```css\n:root {\n  \u002F* Brand *\u002F\n  --primary: #17110b;          \u002F* espresso brown — primary text & dark surfaces *\u002F\n  --secondary: #e8c98f;        \u002F* golden top note — accents *\u002F\n  --accent-bronze: #a08c6c;\n  --accent-umber: #8a795c;\n\n  \u002F* Light mode (default) *\u002F\n  --bg-primary: #e8dcc8;       \u002F* cream — THE neumorphic surface color *\u002F\n  --bg-secondary: #efe3d0;     \u002F* lifted cream for panels\u002Fgradient surfaces *\u002F\n  --text-primary: #17110b;\n  --text-secondary: #8a795c;\n  --text-success: #3f6b4f;      \u002F* warm sage *\u002F\n  --text-error: #a8402f;       \u002F* warm terracotta *\u002F\n  --border-default: rgba(34, 26, 18, 0.18);\n  --border-error: #a8402f;\n  --border-success: #3f6b4f;\n\n  \u002F* Neumorphic elevation (light) *\u002F\n  --shadow-neu-out: 9px 9px 18px rgba(34,26,18,0.35), -9px -9px 18px rgba(255,251,242,0.90);\n  --shadow-neu-in: inset 6px 6px 12px rgba(34,26,18,0.30), inset -6px -6px 12px rgba(255,251,242,0.85);\n  --shadow-neu-out-hover: 12px 12px 24px rgba(34,26,18,0.42), -12px -12px 24px rgba(255,251,242,0.95);\n\n  \u002F* Required generic tokens *\u002F\n  --radius-sm: 10px; --radius-md: 18px; --radius-lg: 28px;\n  --shadow-sm: 0 2px 6px rgba(34,26,18,0.15);\n  --shadow-md: 0 8px 24px rgba(34,26,18,0.20);\n  --spacing-gap: 1.5rem;\n  --transition-fast: 150ms ease; --transition-normal: 300ms cubic-bezier(0.4, 0, 0.2, 1);\n  --ease-standard: cubic-bezier(0.4, 0, 0.2, 1);\n  --z-dropdown: 100; --z-modal: 1000; --z-toast: 1100;\n  --font-display: 'Cormorant Garamond', serif;\n  --font-base: 'Jost', sans-serif;\n}\n```\n- **Contrast pairing:** every light background token pairs with dark text and vice versa — verify both themes. All text must meet WCAG AA (≥ 4.5:1 body, ≥ 3:1 large text); if `--text-secondary` fails on cream, darken it (e.g., `#6f5f44`) while keeping the hue.\n- **Light mode background:** never pure white. The cream `#e8dcc8` is the page background and the neumorphic surface. Where a near-white is unavoidable, use `#fefefe`.\n- **Gradients must be token-driven:** define `--gradient-gold: linear-gradient(135deg, #e8c98f, #a08c6c)` and `--gradient-surface: linear-gradient(145deg, #efe3d0, #e2d4bd)` and reference them via `var()`.\n\n**1.3 Mandatory Dark Mode Support**\n- **Exception Clause (source spec: Light ✓ \u002F Dark ○):** Light mode is the **default and primary presentation**; dark mode is still **mandatory** and must be a fully tuned warm dark-brown variant — not a gray afterthought.\n- **Implementation:** define a `.dark` class on `\u003Chtml>` overriding tokens: `--bg-primary: #17110b`, `--bg-secondary: #221a12`, `--text-primary: #e8dcc8`, `--text-secondary: #a08c6c`, gold `--secondary` unchanged, and dark neumorphic shadows (`--shadow-neu-out: 9px 9px 18px rgba(0,0,0,0.65), -9px -9px 18px rgba(232,220,200,0.06)` plus matching inset). Background and text must swap purely via variables — **no HTML restructuring**.\n- **Persistence:** `localStorage` (e.g., key `parfum-theme`), falling back to `prefers-color-scheme` on first visit; a visible toggle in the navbar with correct `aria-pressed` and `aria-label` states.\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- **All layout via Flexbox.** Every flex container **must default to `align-items: center`** unless an exception is explicitly justified (the Hero \"scent organ\" pipes use `align-items: flex-end` to sit on a baseline — the only permitted exception).\n- **Mobile-first:** rows convert to columns below ~768px; no horizontal scrolling at any width; `overflow-x: clip` on `body` as a safety net.\n\n**1.5 Framework & Naming**\n- **No framework CDN.** Use clean, hand-written custom CSS in `style.css`, organized in cascade layers — `@layer base, components, utilities` — mirroring Tailwind's architecture. All classes are semantic and reusable (`.btn`, `.card`, `.orb`).\n- **BEM everywhere, no mixed conventions:** `.hero__title`, `.card--featured`, `.faq__item`, `.nav__toggle`, `.footer__link-group`, `.btn--primary`, `.btn--ghost`, `.btn--danger`.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- **Fonts:** Google Fonts only — **Cormorant Garamond** (display: headlines, weights 500–700, italic available for flavor) and **Jost** (body\u002FUI, weights 300–600). Bind via `\u003Clink>` tags to `--font-display` and `--font-base`. Body base size ≥ 16px, generous line-height.\n- **Icons:** Google **Material Symbols Rounded** via the standard `\u003Clink>` stylesheet, used with `\u003Cspan class=\"material-symbols-rounded\">`. **Inline SVGs and local icon files are forbidden.**\n\n---\n\n## 2. THEME DESIGN SYSTEM — NEUMORPHISM, GRADIENT, BLUR\n\n**2.1 Surfaces & Shadows**\n- Neumorphic elements must use `background: var(--bg-primary)` (surface = page background) with dual shadows from `--shadow-neu-out` (raised) \u002F `--shadow-neu-in` (pressed wells: inputs, icon badges, step numbers). Cards may use `--gradient-surface` for a barely-there warm lift.\n- **Pressed = inset:** buttons \"sink\" on `:active` (shadow flips to `--shadow-neu-in` + `transform: scale(0.97)`); this is the signature neumorphic tactile feedback.\n\n**2.2 Gradients & Blur**\n- **Gradient accents:** gold `--gradient-gold` on the primary CTA, the \"Most Popular\" badge, icon highlights, and one gradient-text headline (`background-clip: text` with a solid fallback color declared first). Dark mode keeps the gold gradient.\n- **Blur (two sanctioned uses):** (1) 2–3 decorative \"scent orbs\" per band — absolutely positioned radial gradients (gold\u002Fbronze at low alpha), `border-radius: 50%`, `filter: blur(60px)`, `aria-hidden=\"true\"`, `pointer-events: none`; (2) the sticky navbar as frosted glass — `backdrop-filter: blur(12px)` with `-webkit-` prefix and a solid translucent fallback. No other heavy blur.\n- **CSS filters:** tasteful `brightness()` on button hover and icon glows; nothing garish.\n\n**2.3 Motion & Transforms**\n- Every state change transitions with `var(--transition-normal)` \u002F `var(--transition-fast)`. Cards `translateY(-2px)` + deeper shadow on hover; FAQ icons rotate 180°; orbs may drift on a slow keyframe.\n- **`prefers-reduced-motion: reduce`** must collapse animations to opacity-only or none.\n\n**2.4 Neumorphism Accessibility Guardrails (Non-Negotiable)**\n- Shadows **never** communicate state alone — pair with color, icon, or text.\n- `:focus-visible` must render a distinct ring: `outline: 2px solid var(--secondary); outline-offset: 3px;` — soft shadows do not qualify as focus indication.\n- Minimum 44×44px touch targets; verify contrast in **both** themes.\n\n---\n\n## 3. COMPONENT DESIGN SPECIFICATIONS\n\n**3.1 Button Component (`.btn` + variants `.btn--primary`, `.btn--ghost`, `.btn--danger`)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` pill-shaped (`border-radius: 999px`), ≥ 44px height. Primary = gold gradient with `--primary` text; Ghost = neumorphic raised cream with dark text; Danger = terracotta fill\u002Fborder, visually distinct in both themes.\n- **Hover:** `filter: brightness(1.05)` + deeper `--shadow-neu-out-hover`, `cursor: pointer`.\n- **Focus:** visible gold ring per § 2.4.\n- **Active\u002FPressed:** inset shadow swap + `transform: scale(0.97)`.\n- **Loading (`.is-loading`):** disables pointer events, blocks double-clicks, renders a CSS border spinner (or rotating Material Symbol) inside the pill **without changing button dimensions**.\n- **Disabled:** `opacity: 0.5; filter: grayscale(0.6); cursor: not-allowed;` no shadow flip.\n- **Success\u002FError (`.is-success` \u002F `.is-error`):** temporary feedback states tinted by `--text-success` \u002F `--text-error`.\n\n**3.2 Card Component (`.card`, `.card--featured`)**\n- **Default:** flexible Flexbox column, `--radius-lg`, `--shadow-neu-out`, subtle `--border-default`, padding via `--spacing-gap`.\n- **Hover:** `translateY(-2px)` + `--shadow-neu-out-hover`.\n- **Focus-within:** border turns gold when any child link\u002Fbutton is focused.\n- **Loading (Skeleton):** define `.skeleton` with a shimmer `@keyframes` (gradient sweep) preserving final card dimensions — no layout jump.\n- **Empty State:** a reusable fallback — inset circular Material Symbol + one line of guidance copy.\n\n**3.3 Form & Input (`.input-group`, used in the Final CTA newsletter form)**\n- **Structure:** flex column wrapping a `\u003Clabel>`, the input, and a dedicated error feedback `\u003Cdiv>`.\n- **States (all styled):** Empty (inset neumorphic well), Focused (gold ring), Filled, Valid (success border + `check_circle` icon), Invalid (`--border-error`, red helper text, `error` icon), Disabled, Read-only.\n- **Behavior:** client-side email validation; errors announced via an `aria-live=\"polite\"` container; success triggers a `.is-success` state + toast.\n\n**3.4 FAQ Accordion (`.faq__item`)**\n- Each item: a `\u003Cbutton class=\"faq__question\">` with `aria-expanded` + `aria-controls`, and a panel with `role=\"region\"` + `aria-labelledby`. Open\u002Fclose animated in pure CSS (grid-rows or max-height transition) with the `expand_more` icon rotating 180°. Fully keyboard operable.\n\n**3.5 Modal & Toast**\n- **Toast (mandatory):** bottom toast for newsletter success and pricing CTA feedback — `aria-live=\"polite\"`, `--z-toast`, slide-up transition, auto-dismiss.\n- **Modal (mandatory spec if any dialog is used, e.g., a plan-detail dialog):** opening\u002Fopen\u002Floading\u002Fsuccess\u002Fclosing states animated via CSS; centered flex overlay (`align-items: center`), backdrop, Material Symbol close button, focus trapping, closable via `Esc` and overlay click, `--z-modal`.\n\n**3.6 Nav & Footer Elements**\n- **Navbar:** frosted sticky header — brand wordmark, section anchor links (smooth scroll + `scroll-margin-top` offsets, guarded by reduced-motion), theme toggle, mobile hamburger (`aria-expanded`, panel at `--z-dropdown`).\n- **Include a \"Skip to content\" link** as the first focusable element.\n\n---\n\n## 4. PAGE SECTION REQUIREMENTS (English copy, authored by you)\n\n**4.1 Hero**\n- `\u003Ch1>` in display serif with a musical-olfactory promise (e.g., *\"Every fragrance is a symphony. Compose yours.\"*) plus a subheadline explaining the organ metaphor (top, heart, base notes as playable keys).\n- Two CTAs: primary **\"Compose Your Scent\"** (scrolls to Pricing), ghost **\"How It Works\"**.\n- **Signature visual — the Scent Organ, pure CSS (no images):** a flex row (`align-items: flex-end` — the justified exception) of 9–12 rounded vertical \"pipes\" of varying heights; several pipes use `--gradient-gold`; hovering a pipe raises it (`translateY(-6px)`) and brightens it. Behind: 2–3 blurred gold\u002Fcream orbs per § 2.2.\n\n**4.2 Features — 3 Cards (\"The Three Notes\")**\n- **Top Notes** (`graphic_eq` icon): the opening chord — citrus and aromatics, the first impression.\n- **Heart Notes** (`favorite` icon): the melody — florals and spices, the composition's character.\n- **Base Notes** (`layers` icon): the resonance — woods, musks, amber, the lasting trail.\n- Each: circular inset icon well (neumorphic), `\u003Ch3>`, 2–3 sentences of authored copy, `.card` states per § 3.2.\n\n**4.3 How It Works — 3 Steps**\n- Flex row → column on mobile. Numbered circular neumorphic badges (1, 2, 3 — current step highlighted in gold), a subtle connecting line, `\u003Ch3>` + copy per step: **Choose Your Notes** → **Play the Composition** → **Bottle & Receive** (invent coherent, luxurious detail, e.g., maceration time, flacon size).\n\n**4.4 Testimonials — 3 Cards**\n- Each: `format_quote` icon, 5-star rating (star Material Symbols with `aria-label=\"Rated 5 out of 5\"`), authored English quote, circular **CSS monogram avatar** (inset circle with initials — no images), name + role.\n\n**4.5 Pricing — 3 Tiers**\n- **Discovery \u002F Signature (featured) \u002F Maestro** — realistic, coherent pricing you invent (e.g., $49 \u002F $89 \u002F $199) with billing notes. Feature lists use `check` Material icons. Featured card: slightly larger, `--gradient-gold` \"Most Popular\" badge, gold border, deeper shadow, gold primary CTA; side tiers use ghost CTAs. CTA click: loading state → success toast (§ 3.1, § 3.5).\n\n**4.6 FAQ — 5 Questions (Accordion per § 3.4)**\n- Author questions on longevity, ingredients\u002Fnaturality, shipping, returns, and allergen safety.\n\n**4.7 Final CTA**\n- Full-bleed band: warm gradient + blurred orbs (light: cream→gold; dark: espresso + gold glow). Display-font headline, supporting line, the newsletter `.input-group` (§ 3.3) with gold submit button, plus a ghost secondary CTA.\n\n**4.8 Footer**\n- Flex-wrap columns: brand + one-line description + circular neumorphic social icon buttons (Material Symbols, descriptive `aria-label`s); link groups **Explore** (anchors to the real sections), **Company** (About, Journal, Contact), **Legal** (Privacy, Terms, Accessibility — `href=\"#\"` acceptable only because no target pages exist); copyright line.\n\n---\n\n## 5. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid type\u002Fspacing, breakpoints without horizontal overflow; nav collapses to hamburger below ~768px.\n- **Smooth animations:** transitions on all state changes; `prefers-reduced-motion` fully respected; smooth scrolling with reduced-motion fallback.\n- **Accessibility (a11y):** AA contrast in **both** modes; never color\u002Fshadow-only state signaling; semantic HTML5 landmarks (`header`, `nav[aria-label]`, `main`, `section[aria-labelledby]`, one `\u003Ch1>`, `footer`); logical DOM\u002Ffocus order; full keyboard operability; `aria-live` for all dynamic feedback (form errors, toasts, loading).\n- **Mandatory visual feedback:** every hover, click, and submission produces a visible state change.\n- **Destructive actions:** define `.btn--danger` with distinct terracotta styling readable in light and dark themes, even though the landing page may not use it.\n\n---\n\n## 6. DELIVERABLE & OUTPUT FORMAT\n\n- **Files:** separate `index.html`, `style.css`, `script.js`. HTML contains **no** `style=` attributes and **no** inline `\u003Cscript>` beyond the single deferred `\u003Cscript src=\"script.js\" defer>\u003C\u002Fscript>` entry point. JS uses `addEventListener` only — zero inline handlers.\n- **JS scope (from-scratch build):** theme toggle with persistence, mobile menu, FAQ accordion, newsletter validation, pricing CTA loading\u002Fsuccess simulation, toast component. All logic in `script.js`.\n- **Naming:** BEM exclusively, per § 1.5 — never mix conventions.\n- **Assets:** Google Fonts + Material Symbols only; all visuals (orbs, organ pipes, avatars, badges) are pure CSS. No external images, no lorem ipsum — every heading, paragraph, question, and testimonial is final, polished English copy (the French brand name is preserved as a proper noun).\n- **Output:** the complete, finished code for all three files in one attempt — nothing omitted, nothing deferred.\n",1791954993215]
