## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
* **No Inline CSS:** The `style="..."` attribute is **forbidden** anywhere in the HTML.
* **Class/ID Selectors Only:** All design properties, layout rules, and states must be targeted via class or ID selectors in `style.css`.
* **Minimal HTML Modifications:** HTML must remain clean, semantic, and style-agnostic. Changing the site's look must require editing only the CSS file, never the markup.

### 1.2 CSS Variables & Theme Tokens
Store all visual tokens in `:root` and override per theme. Use exactly this palette:

**Light mode (`:root`):**

| Token | Value | Usage |
|---|---|---|
| `--primary` | `#C67B5C` (Terracotta) | Decorative fills, icon tiles, borders, badges — **never body text** (fails contrast on cream) |
| `--primary-deep` | `#A0522D` | Terracotta-toned heading/accent text on light backgrounds |
| `--primary-action` | `#8B4513` (Earth Brown) | Primary button background, always paired with `--bg-primary` text |
| `--secondary` | `#6B7B3C` (Olive Green) | Secondary accents, outlines, highlights |
| `--bg-primary` | `#F5F0E1` (Soft Cream) | Page background — **never `#ffffff`**; use `#fefefe` if a near-white is required |
| `--bg-secondary` | `#EAE0CC` (softened Sand Beige) | Cards, alternating section bands |
| `--bg-sand` | `#D4C4A8` | Decorative fills, dividers, texture bands |
| `--text-primary` | `#3A2D23` (deep soil brown) | Headings and body text |
| `--text-secondary` | `#6B5B4B` (warm taupe) | Muted copy |
| `--text-success` | `#557032` (deep olive) | Success feedback |
| `--text-error` | `#A93E2A` (clay red) | Error feedback |
| `--border-default` | `rgba(139, 69, 19, 0.22)` | Card/input borders |
| `--border-success` / `--border-error` | Derived from `--text-success` / `--text-error` | State borders |
| `--focus-ring` | `#A0522D` | Focus outlines |

**Dark mode (defined under both `@media (prefers-color-scheme: dark)` and `.dark`):** `--bg-primary: #211A14` (deep soil); `--bg-secondary: #2B221A`; `--bg-sand: #3A2E22`; `--text-primary: #F5F0E1`; `--text-secondary: #CBBDA7`; `--primary: #D89B7E`; `--primary-deep: #E0A88C`; `--primary-action: #C67B5C` (button background paired with `#211A14` text); `--secondary: #A9BC77`; `--border-default: rgba(245, 240, 225, 0.16)`; deeper warm shadows.

* **Contrast Pairing:** Every light background token must pair with a dark text token and every dark background with a light text token — enforced in **both** themes.
* **Hard a11y constraint:** Every text/background pair must pass WCAG AA — 4.5:1 for normal text, 3:1 for large text (≥24px, or ≥19px bold). Verify all pairs; adjust token lightness if a pair fails.
* **Radii (organic, varied):** `--radius-sm: 8px`; `--radius-md: 16px`; `--radius-lg: 24px`; `--radius-organic: 58% 42% 55% 45% / 48% 56% 44% 52%` for blob shapes.
* **Shadows (warm-tinted, soft):** `--shadow-sm: 0 2px 10px rgba(58, 45, 35, 0.08)`; `--shadow-md: 0 10px 28px rgba(58, 45, 35, 0.16)`; darker variants in dark mode.
* **Spacing & Motion:** `--spacing-gap: 1.5rem`; `--transition-fast: 160ms`; `--transition-normal: 320ms`; `--ease-standard: cubic-bezier(0.22, 1, 0.36, 1)` (natural ease-out).
* **Elevation:** `--z-header: 20`; `--z-dropdown: 30`; `--z-modal: 50`; `--z-toast: 60`.

### 1.3 Mandatory Dark Mode Support
* **Implementation:** Dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`; the class must override the media query.
* **Theme Switching:** Backgrounds and text must flip seamlessly via CSS variables only — no HTML restructuring.
* **Persistence:** Store the user's choice in `localStorage` (e.g., key `nature-distilled-theme`), falling back to `prefers-color-scheme` on first visit. First-time visitors get the media-query default (no flash); returning visitors get the stored preference applied by `script.js` on load.
* **Toggle Control:** A visible header toggle using Material Symbols (`light_mode` / `dark_mode`) with correct `aria-pressed` and dynamic `aria-label` ("Switch to dark mode" / "Switch to light mode").
* **Exception note:** The source style spec marks dark mode as "partial" — disregard that: **full dark mode is mandatory**. Every section, component, and state must be dark-mode complete.

### 1.4 Flexbox Layout & Mobile-First Alignment
* **Default Alignment Rule:** Every flex container defaults to `align-items: center` unless an exception is explicitly justified in a CSS comment (e.g., `.input-group` and equal-height card grids use `stretch`).
* **Mobile-Friendly First:** Author base styles for small screens and scale up with `min-width` media queries. Multi-column layouts (features, steps, testimonials, pricing, footer link groups) collapse to a single column on small viewports. **No horizontal scrolling at any width from 320px up.**
* Wrap all section content in a centered max-width container (e.g., `72rem`).

### 1.5 Framework Default & CSS Architecture
* No framework build step. Write clean, hand-authored CSS in `style.css`, organized in Tailwind-style layers: **tokens → base/reset → layout → components → utilities**.
* All styling maps to reusable component classes (`.btn`, `.card`, `.input-group`, `.badge`, `.section`, `.container`). No utility-class soup; component-first naming.

### 1.6 Typography & Icons (Google Fonts Mandatory)
* **Text:** Load Google Fonts via `<link>`: **'Nunito Sans'** (humanist sans-serif) as `--font-base` (weights 400/600/700/800) and **'Fraunces'** as `--font-display` for headings (warm, handmade character).
* **Icons:** Google Material Symbols (**Rounded** style) via `<link>`, using ligature names (`eco`, `spa`, `check`, `star`, `close`, `expand_more`, `arrow_forward`, `light_mode`, `dark_mode`, `progress_activity`, `local_shipping`, `recycling`, `menu`).
* **Forbidden:** raw inline SVGs, local icon files, and emoji used as icons. (A grain texture defined *inside the CSS file* as an SVG `feTurbulence` data-URI `background-image` is permitted — it is a texture, not an icon, and never an inline `<svg>` element in the HTML.)

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Button Component (`.btn`, `.btn--primary`, `.btn--secondary`, `.btn--ghost`)
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` pill-shaped (`border-radius: 999px`), minimum touch target 44×44px. Primary = filled `--primary-action`; Secondary = 1.5px solid `--secondary`, transparent background; Ghost = text-only with underline on hover.
* **Hover:** Brightness/darkness shift plus `--shadow-sm`; `cursor: pointer`; `transition: var(--transition-fast) var(--ease-standard)`.
* **Focus:** `:focus-visible` renders a 2px `var(--focus-ring)` outline with 3px offset — clearly visible in both themes.
* **Active/Pressed:** `transform: scale(0.97)`.
* **Loading (`.is-loading`):** Disables pointer events, prevents double-clicks/double-submits, and renders a rotating `progress_activity` Material Symbol or CSS spinner **without changing button dimensions**.
* **Disabled:** `opacity: 0.5`, `filter: grayscale(0.4)`, `cursor: not-allowed`.
* **Success/Error (`.is-success` / `.is-error`):** Temporary feedback recoloring driven by `--text-success` / `--text-error` (used by the newsletter submit flow).

### 2.2 Card Component (`.card`)
* **Default:** Flexible flexbox column, `--bg-secondary` surface, 1px `--border-default`, `--radius-lg`, `--shadow-sm`, `padding: var(--spacing-gap)`.
* **Hover (interactive cards):** `transform: translateY(-2px)` + `--shadow-md` via `var(--transition-normal) var(--ease-standard)`.
* **Focus-within:** Border color shifts to `--primary-deep` when a child link/button receives focus.
* **Loading (Skeleton):** Define `.skeleton` with a sand-toned `@keyframes shimmer` gradient sweep and reserved `min-height`s so future loading states cause no layout jump.
* **Empty State:** Define an `.empty-state` pattern — centered Material Symbol inside a `--radius-organic` blob plus clear guidance text.
* **Variants:** `.card--feature` (icon tile with `--radius-organic` background tinted terracotta); `.card--testimonial` (quote, 48px avatar from `https://picsum.photos` with a descriptive seed, name, role, five filled `star` icons with `aria-label="Rated 5 out of 5"`); `.card--pricing` (feature list with `check` icons; the featured tier gets `.card--featured`: 2px `--primary` border, a "Most Popular" `.badge`, and slight scale/elevation at ≥1024px).

### 2.3 Form & Input Requirements (`.input-group`)
* Include one newsletter email capture in the **Footer**.
* **Structure:** Flex column (`align-items: stretch` — documented exception) wrapping a `<label>`, the `<input>`, and a dedicated `.error-message` container with `aria-live="polite"` and reserved min-height to prevent layout shift.
* **States:** Empty; `:focus` (2px `--focus-ring` ring + subtle shadow); filled; valid (`.is-valid`: `--border-success` + small `check` icon); invalid (`.is-invalid`: `--border-error`, error text in `--text-error`, error icon, message announced via the live region); disabled; read-only.
* **Behavior (`script.js`):** Validate email on submit (`preventDefault`); invalid → error state + message; valid → button enters loading state, then success state with an inline confirmation message in the live region.

### 2.4 FAQ Accordion / Interactive Disclosure
* Build each item as a `<button aria-expanded="true|false">` trigger controlling a panel with `role="region"` and `aria-labelledby` (or native `<details>`/`<summary>` with equivalent semantics).
* **States:** Closed → Opening → Open → Closing, animated via CSS (`grid-template-rows: 0fr → 1fr` or equivalent) using `var(--transition-normal) var(--ease-standard)`; chevron `expand_more` icon rotates 180° with a transform transition.
* Fully keyboard operable (Enter/Space); optionally allow only one open panel — if so, keep all `aria-expanded` values accurate.
* Write 5–6 realistic FAQ entries (sourcing, materials, shipping, returns, sustainability practices).
* **If any modal/popup is added:** centered flex overlay (`align-items: center`), backdrop, Material Symbol `close` button, focus trap, close via `Esc` and overlay click, animated open/close transitions.

### 2.5 Section-Specific Requirements
* **Header:** Sticky, `--bg-primary` with translucent backdrop blur and bottom border; logo = `eco` icon + "Nature Distilled" wordmark in `--font-display`; anchor links (Features, How It Works, Testimonials, Pricing, FAQ) with hover/focus underline states; theme toggle; compact CTA button. On mobile, links collapse into an accessible hamburger menu (`menu` icon, `aria-expanded`, `aria-controls`, `--z-dropdown`) — no horizontal scroll.
* **Hero:** Eyebrow badge, `h1` in `--font-display` with one terracotta-deep accent word, subcopy, primary + secondary CTA, and a trust row (e.g., "100% natural · Small-batch handmade · Plastic-free"). Decorative layer: layered organic blob shapes (CSS gradients + `--radius-organic`) with grain texture, a gentle float animation, and **subtle parallax on scroll** (transform-only, ≤12px, `requestAnimationFrame`-throttled, disabled under `prefers-reduced-motion`). A `picsum.photos` seeded hero image is permitted if it strengthens the composition.
* **Features:** Three `.card--feature` items (e.g., "Sustainably Sourced", "Small-Batch Handmade", "Plastic-Free & Refillable") with Material Symbol icons.
* **How It Works:** Three steps with organic numbered badges (01/02/03) connected by a dashed line on desktop, stacked column on mobile.
* **Testimonials:** Three `.card--testimonial` items in a responsive grid (3 → 2 → 1 columns).
* **Pricing:** Three tiers with realistic names/prices (e.g., "Seedling", "Bloom" — featured, "Harvest"), per-tier feature lists, and CTAs (featured tier = primary button, others = secondary).
* **Final CTA:** Full-width warm gradient band (`#B5651D` → `#C67B5C`), cream display heading, one primary button (cream background, clay text — verify AA contrast).
* **Footer:** Brand blurb + newsletter `.input-group`; three secondary link groups (Company / Support / Legal — About, Contact, FAQ, Shipping, Returns, Privacy, Terms); social icons (Material Symbols with `aria-label`s); dynamic copyright year. Secondary links may use `href="#"` for out-of-scope routes but must show visible hover/focus states.

## 3. CORE UX & MICRO-INTERACTION RULES

* **Responsive by Default:** Fluid `clamp()` typography, `auto-fit` grids, zero horizontal overflow from 320px to wide desktop; smooth anchor scrolling (`scroll-behavior: smooth`, guarded by `prefers-reduced-motion`) with `scroll-margin-top` compensating for the sticky header.
* **Theme Effects (Mandatory):** A global grain overlay via `body::after` (CSS-only noise — `feTurbulence` data-URI or layered radial-gradient speckle; `opacity ≈ 0.05`; `pointer-events: none`; adapts per theme); soft warm shadows; organic varied radii; natural ease-out on every transition.
* **Smooth Animations:** All state changes transition with `var(--transition-fast)` / `var(--transition-normal)` and `var(--ease-standard)`; fully respect `prefers-reduced-motion` (disable parallax, float, shimmer, smooth scroll).
* **Accessibility (a11y):** Semantic landmarks (`header`, `nav`, `main`, `section[aria-labelledby]`, `footer`), skip-to-content link, logical heading order h1 → h2 → h3, visible focus on every interactive element, ≥44px touch targets, never color-only state communication (pair color with icons/text), `aria-live` regions for dynamic feedback, descriptive `alt` text, and AA-compliant contrast in **both** themes.
* **Mandatory Visual Feedback:** Every hover, click, focus, and submission triggers a visible state change.
* **Destructive Actions:** Not applicable to this page, but if any destructive control is introduced, style it via a token-driven `.btn--danger` class that is visually distinct in both themes.

## 4. DELIVERABLE & OUTPUT FORMAT

* **File Structure:** Three separate, complete files — `index.html`, `style.css`, `script.js`. The HTML contains exactly one `<script src="script.js" defer>` reference and **no** inline scripts or inline styles.
* **Naming Convention:** BEM throughout (`.card`, `.card--featured`, `.card__title`, `.input-group__error`) — never mix conventions.
* **Copy:** All user-facing copy in **English**, on-brand, and realistic — genuine headlines, feature descriptions, named testimonials with roles, substantive FAQ answers, and concrete pricing details. **No lorem ipsum.**
* **JS Scope:** Vanilla, dependency-free — theme toggle + persistence, mobile menu, FAQ accordion, newsletter validation/feedback, reduced-motion-aware parallax, dynamic copyright year.
* **Output:** Final code for all three files, ready to run by opening `index.html` in a browser.
