## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
- All styling lives in a dedicated `style.css` file. **Forbidden:** the `style="..."` attribute anywhere in HTML.
- All design properties, layout rules, and states are targeted via class/ID selectors only.
- HTML must remain clean, semantic, and style-agnostic — changing the theme must require editing only the CSS file.

### 1.2 CSS Variables & Theme Tokens
Define all tokens in `:root` and theme classes:

- **Colors:** `--primary: #001F3F` (Midnight Mirage), `--accent: #74C365` (Mantis Green), `--secondary-bg: #F6F7ED` (Praxeti White), plus `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`.
- **Secondary palette tokens:** `--spring-lime: #DBE64C`, `--book-green: #00804C`, `--nuit-blanche: #1E488F`.
- **Contrast pairing:** every light background token pairs with dark text; every dark background token pairs with light text (`#F6F7ED`). Never pure white — use `#fefefe` where near-white is required.
- **Radius & shadows:** `--radius-sm`, `--radius-md: 10px`, `--radius-lg`, `--shadow-sm`, `--shadow-md: 0 8px 32px rgba(0,31,63,0.4)`.
- **Spacing & transitions:** `--spacing-gap`, `--transition-fast`, `--transition-normal: 0.3s cubic-bezier(0.4, 0, 0.2, 1)`, `--ease-standard`.
- **Elevation:** `--z-dropdown`, `--z-modal`, `--z-toast`.

### 1.3 Mandatory Dark Mode
- **Dark mode is the default aesthetic** (deep `#001F3F` backgrounds, `#F6F7ED` text) — but a full light mode must also exist.
- Provide light-mode tokens via a `.light` class (and/or `@media (prefers-color-scheme: light)` fallback); dark tokens via `.dark`.
- Theme toggle button in the navbar with correct `aria-pressed` and `aria-label`; choice persists via `localStorage`, falling back to `prefers-color-scheme` on first visit. Switching themes must require zero HTML restructuring.
- In light mode, backgrounds shift to soft `#F6F7ED`/`#fefefe` tones with `#001F3F` text and `#00804C` accents — contrast must remain AA-compliant in both modes.

### 1.4 Flexbox Layout & Mobile-First Alignment
- Build all layout structures with Flexbox (`display: flex`).
- Every flex container defaults to `align-items: center` unless explicitly justified otherwise.
- Mobile-first: rows convert to columns on small viewports; **zero horizontal scrolling** at any breakpoint.

### 1.5 Framework Default
- Use Tailwind CSS (CDN or build) with custom CSS driven by `@layer`/`@apply`, or clean custom CSS — either way, all utilities must map back to the CSS variables and reusable generic classes (`.btn`, `.card`, `.input-group`, `.section-title`).

### 1.6 Typography & Icons (Google Fonts Mandatory)
- **Text fonts:** Google Fonts — `DM Serif Display` for headings (`--font-heading`), `DM Sans` for body (`--font-body`). Include via `<link>` or `@import`.
- **Icons:** Google Material Symbols only. **No raw inline SVGs, no local icon files.**
- **Exception clause:** the source spec requests "botanical SVG illustrations" — decorative botanical line art is permitted ONLY via inline SVG `<defs>`/paths using `currentColor`, kept in a single reusable pattern/sprite block; all functional icons remain Google Material Symbols.

## 2. COMPONENT DESIGN SPECIFICATIONS

### 2.1 Buttons
All states via CSS classes:
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` min touch target 44×44px. Primary button: `#74C365` background, `#001F3F` text, `--radius-md`.
- **Hover:** brightness shift + subtle green glow (`box-shadow: 0 0 20px rgba(116,195,101,0.35)`), `cursor: pointer`.
- **Focus:** distinct focus ring via `outline`/`box-shadow` using `--accent`.
- **Active:** `transform: scale(0.97)`.
- **Loading:** disables interaction, prevents double-clicks, CSS spinner (or animated Google Icon) that does not distort button dimensions.
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Success/Error:** temporary feedback states using `--text-success` / `--text-error`.
- **Danger:** generic `.btn-danger` class, visually distinct in both themes.

### 2.2 Cards (Features, Pricing, Testimonials)
- **Default:** Flexbox layout, `--bg-secondary`/translucent `rgba(0,31,63,0.6)` panels over layered backgrounds, `border: 1px solid rgba(116,195,101,0.15)`, `--shadow-md`.
- **Hover:** `transform: translateY(-2px)` + glow shift.
- **Focus-within:** border highlights when a child link/button receives focus.
- **Skeleton:** shimmer animation defined in CSS.
- **Empty state:** Google Icon + guidance text fallback structure.

### 2.3 Forms (Final CTA / Newsletter block)
- States: empty, focused (outline ring), filled, valid (success border/icon), invalid (error border, red text, error icon), disabled, read-only.
- Structure: flex container wrapping label, input, dedicated error feedback container with `aria-live="polite"`.

### 2.4 FAQ Accordion & Modals
- FAQ: semantic `<details>`/`<summary>` or ARIA-compliant custom accordion with keyboard operability and animated open/close via CSS transitions.
- Any modal/popup: centered flex container, backdrop overlay, Google Icon close button, focus trapping, closes via `Esc` and overlay click; states: opening, open, loading, success/error, closing — all CSS-animated.

## 3. CORE UX & MICRO-INTERACTION RULES

- **Responsive by default:** fluid sizing, no horizontal overflow at any viewport.
- **Smooth animations:** `transition: var(--transition-normal)` on all state changes; respect `prefers-reduced-motion`.
- **Accessibility:** AA contrast in both light and dark modes; never rely on color alone to communicate state; semantic HTML5 (`<header>`, `<nav>`, `<main>`, `<section>`, `<footer>`); correct ARIA roles/labels on custom widgets; logical DOM/focus order; full keyboard operability; `aria-live` regions for dynamic feedback.
- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
- **Visual effects:** deep dark backgrounds with vivid green accents, layered depth via translucent `rgba` panels, crisp light-on-dark typography, subtle glow on interactive elements, fine 1px low-opacity borders (`rgba(116,195,101,0.15)`).

## 4. DELIVERABLE & OUTPUT FORMAT

- **Files:** separate `index.html`, `style.css`, `script.js`. No inline `<script>` beyond a single deferred entry-point reference.
- **Naming convention:** one consistent convention (BEM or a fixed utility set) across the entire deliverable — never mix.
- **Copy:** all user-facing copy in **English**, written as real marketing copy for a premium botanical brand — no lorem ipsum, no unrequested placeholders.
- **Section content:** Hero with headline, subheadline, dual CTA buttons, and botanical decorative art; Features as 3 cards with Material Symbols icons; How It Works as 3 numbered steps; Testimonials with at least 3 entries (name, role, quote, avatar placeholder styling); Pricing with 3 tiers (highlight the middle tier as "Most Popular"); FAQ with at least 5 questions; Final CTA with email capture form; Footer with brand block, secondary link columns, and legal row.
