Your task is to code a complete, production-quality Landing Page on the first attempt. Theme: **Nature \u002F Botanical Elements** — an infographic-style, eco-friendly landing page with full Light and Dark mode support.\n\n---\n\n## 0. PROJECT BRIEF & THEME DIRECTION\n\n**Theme:** Nature \u002F Botanical Elements (translated from \"Natureza \u002F Elementos Botânicos\"). Style type: Infographic. Era: Nature-Inspired. Keywords: botanical illustrations, floral ornaments, organic shapes, leaf motifs, nature-inspired, eco-friendly, fresh, natural flow.\n\n**Sections (in this order):**\n1. Sticky Header with navigation\n2. Hero\n3. Features (3 cards)\n4. How It Works (3 steps, infographic flow)\n5. Testimonials\n6. Pricing (3 tiers)\n7. FAQ (accordion)\n8. Final CTA\n9. Footer with secondary links\n\n**Color Palette → Token Mapping:**\n\n*Light mode (default):*\n- `--bg-primary`: `#F6FAF3` (soft botanical near-white — **never pure `#FFFFFF`**)\n- `--bg-secondary`: `#FEFEFE` (card surfaces)\n- `--primary`: `#2B5F2B` (Forest Green — headings, primary buttons)\n- `--secondary`: `#27AE60` (Emerald — accents, links, success)\n- `--text-primary`: `#2B5F2B`; `--text-secondary`: `#5C6E5C` (darkened sage — do **not** use `#95A5A6` for text; reserve Cool Grey for decorative borders\u002Fdividers only)\n- `--accent-amber`: `#F39C12` (highlights, \"Most Popular\" badge, warm glow). Never use amber as small text on light backgrounds; amber fills must carry dark text (`#2E1F05`)\n- `--accent-info`: `#3498DB` (FAQ\u002Finformational accents); `--accent-premium`: `#9B59B6` (premium pricing tier)\n- `--text-error` \u002F `--border-error`: `#E74C3C`; `--text-success` \u002F `--border-success`: `#27AE60`\n\n*Dark mode:*\n- `--bg-primary`: `#0F2113` (deep forest); `--bg-secondary`: `#1A3120` (elevated surfaces)\n- `--text-primary`: `#EAF5EA` (soft mint); `--text-secondary`: `#AFC6AF`\n- Forest Green `#2B5F2B` is too dark for dark-mode text — reserve it for surfaces\u002Fborders; use Emerald fills with dark text for primary buttons\n- Lighten blue\u002Fpurple accents for contrast (`#5DADE2`, `#AF7AC5`); amber works on dark surfaces\n\n**Contrast pairing rule:** every light background token pairs with a dark text token, and every dark background token pairs with a light text token — enforced in both themes.\n\n**Visual Effects:** warm natural lighting (soft radial amber\u002Fgreen glows), soft diffuse shadows, leaf sway animations, floral border reveals on scroll, organic shape morphing (blob `border-radius` \u002F `clip-path`), nature-inspired transitions.\n\n**Typography:** Google Fonts — elegant serif for headings (Playfair Display or Lora), rounded sans for body (Nunito or Quicksand), bound to `--font-heading` \u002F `--font-base`.\n\n**Copy:** All user-facing copy in **English**. Invent one coherent fictional botanical\u002Feco brand (e.g., plant-care subscription, botanical wellness, eco marketplace) and write realistic, specific copy for every section: headlines, feature titles\u002Fdescriptions, step explanations, testimonial quotes with names and roles, pricing plan names\u002Ffeatures\u002Fprices, 5–6 FAQ questions with answers, CTA text, and footer link labels.\n\n**Botanical artwork — explicit exception clause:** The source specification requests \"SVG botanical illustrations\" and \"floral SVG patterns.\" Because raw inline SVGs are forbidden (see rule 1.6), ALL botanical motifs, floral ornaments, leaf shapes, and organic dividers must be constructed with **CSS only** — `clip-path` organic shapes, blob `border-radius`, layered\u002Frepeating gradients (vine patterns), and pseudo-elements — plus Google Material Symbols (`eco`, `spa`, `local_florist`, `filter_vintage`, `park`, `nature`, `water_drop`, `sunny`, `recycling`, `psychiatry`) for iconography.\n\n---\n\n## 1. STRICT RULES & ARCHITECTURE\n\n**1.1 CSS-First Architecture & Zero Inline CSS**\n- All styling lives in `style.css`. **No `style=\"...\"` attributes anywhere in the HTML.**\n- All design properties, layout rules, and states are targeted via class or ID selectors only.\n- HTML remains clean, semantic, and style-agnostic — reskinning the site must require CSS edits only, never markup changes.\n\n**1.2 CSS Variables & Theme Tokens**\nDefine all tokens in `:root` (light) and override under `.dark` and `@media (prefers-color-scheme: dark)`:\n- **Colors:** `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`, plus `--accent-amber`, `--accent-info`, `--accent-premium`.\n- **Contrast pairing:** enforced per Section 0 for both themes.\n- **Light background:** `#F6FAF3` \u002F `#FEFEFE` — never `#FFFFFF`.\n- **Radius & shadows:** `--radius-sm` (8px), `--radius-md` (14px), `--radius-lg` (24px); `--shadow-sm`, `--shadow-md` (soft, diffuse, low-opacity — natural lighting, never harsh black shadows).\n- **Spacing & transitions:** `--spacing-gap` (1.5rem), `--transition-fast` (150ms), `--transition-normal` (300ms), `--ease-standard` (organic curve, e.g., `cubic-bezier(0.45, 0.05, 0.35, 1)`).\n- **Elevation:** `--z-dropdown` (100), `--z-modal` (200), `--z-toast` (300).\n\n**1.3 Mandatory Dark Mode Support**\n- Dark mode tokens defined under **both** `@media (prefers-color-scheme: dark)` and a `.dark` class on `\u003Chtml>`\u002F`\u003Cbody>`.\n- Theme switching swaps CSS variables only — no HTML restructuring.\n- **Persistence:** store the user's choice in `localStorage`; fall back to `prefers-color-scheme` on first visit. The media-query tokens act as the no-JS base so there is no flash of the wrong theme.\n- **Toggle control:** a visible sun\u002Fmoon toggle in the header using a Google Material Symbol, with correct `aria-pressed` and `aria-label` (\"Switch to dark mode\" \u002F \"Switch to light mode\").\n\n**1.4 Flexbox Layout & Mobile-First Alignment**\n- Build all layout structures with Flexbox (`display: flex` \u002F Tailwind flex utilities).\n- **Every flex container defaults to `align-items: center`** unless an exception is explicitly justified with a CSS comment. Permitted exceptions: `.input-group` and text-heavy card bodies use `align-items: flex-start` for reading flow.\n- **Mobile-first:** multi-column rows (features, steps, pricing, testimonials) collapse to a single column below ~768px; no horizontal scrolling anywhere (fluid widths, `clamp()` typography, `overflow-x` guard). Breakpoints: ~640px, ~768px, ~1024px.\n\n**1.5 Framework Default & Tailwind CSS Integration**\n- Use Tailwind CSS (CDN or build) or clean custom CSS organized with `@layer` \u002F `@apply`. All utilities must map back to CSS variables, and component design must live in generic reusable classes: `.btn`, `.card`, `.input-group`.\n\n**1.6 Typography & Icons (Google Fonts Mandatory)**\n- Include Google Fonts `\u003Clink>` tags (serif headings + rounded sans body) and bind them to `--font-heading` \u002F `--font-base`.\n- Use **Google Material Symbols** (outlined, variable font) for every icon. **Explicitly forbidden: raw inline SVGs, local icon files, emoji icons.** (Exception for botanical artwork per Section 0 — CSS-built shapes only.)\n\n---\n\n## 2. COMPONENT DESIGN SPECIFICATIONS\n\n**2.1 Button Component (`.btn` + variants)**\n- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Variants: `.btn--primary` (forest\u002Femerald fill), `.btn--secondary` (outline), `.btn--accent` (amber fill + dark text), `.btn--ghost`, `.btn--danger` (red — visually distinct in both themes).\n- **Hover:** brightness\u002Fshadow shift with `cursor: pointer`.\n- **Focus:** distinct ring via `outline` + `box-shadow` using `--secondary`; clearly visible in both themes.\n- **Active\u002FPressed:** `transform: scale(0.97)`.\n- **Loading (`.is-loading`):** disables interactions and prevents double-clicks; renders a CSS border spinner or animated Material Symbol without changing button dimensions.\n- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.\n- **Success\u002FError:** temporary feedback classes driven by `--text-success` \u002F `--text-error`, always pairing an icon + text (never color alone).\n\n**2.2 Card Component (`.card`)**\n- **Default:** flexible Flexbox layout, `--bg-secondary`, `--border-default`, `--radius-lg`, `--shadow-sm`.\n- **Hover (interactive cards):** elevation shift to `--shadow-md` plus subtle `transform: translateY(-2px)`.\n- **Focus-within:** card border highlights in `--secondary` when a child link\u002Fbutton receives focus.\n- **Loading (`.card--skeleton`):** shimmer keyframe animation that preserves layout dimensions.\n- **Empty state:** structured fallback with a Google Icon and clear guidance text.\n\n**2.3 Form & Input Requirements (`.input-group`)**\n- **Structure:** flex container (column, `flex-start` exception) wrapping a `\u003Clabel>`, the `\u003Cinput>`, and a dedicated error feedback element.\n- **States:** empty, focused (outline ring), filled, valid (success border + check icon), invalid (error border, error text + error icon), disabled, read-only.\n- Apply to the Final CTA email capture: validate the email, show inline errors in an `aria-live` region, simulate submission with button loading → success state + toast.\n\n**2.4 Modal \u002F Popup Requirements**\n- Triggered by Final CTA \u002F pricing buttons (\"Get started\").\n- **States:** opening, open, loading, success\u002Ferror, closing — all animated via CSS transitions.\n- **UX:** centered flex overlay (`align-items: center`), dimmed backdrop, `--z-modal`, Google Icon close button (`aria-label=\"Close\"`), keyboard focus trapping, close via `Esc` or overlay click, focus returns to the triggering element.\n\n**2.5 Landing-Page-Specific Components**\n- **Header:** sticky, translucent `--bg-primary` with backdrop blur; logo (eco icon + brand name), nav links with vine-like underline-grow hover\u002Ffocus states, theme toggle, CTA button; mobile hamburger opens a dropdown panel (`--z-dropdown`) that is keyboard operable with `aria-expanded`.\n- **Hero:** serif headline, subcopy, two CTAs; decorative botanical cluster arranged in a circular\u002Fwreath flow of Material Symbol leaves and flowers with staggered leaf-sway animation; organic blob background shapes with slow `border-radius` morphing; warm radial amber glow for soft, diffuse natural lighting.\n- **Features:** 3 `.card` elements, each with a circular leaf-motif icon badge (emerald tint), title, and description; floral border reveal on scroll with staggered delays.\n- **How It Works (infographic):** 3 steps in a flowing arrangement — numbered circular badges connected by organic curved connectors (CSS gradient vine lines); alternating alignment on desktop, vertical vine connector on mobile; reveals in natural flow order.\n- **Testimonials:** 3 cards — quote, CSS initials avatar circle (or person Material Symbol), name, role, star rating (star icons plus `aria-label` such as \"Rated 5 out of 5\" — never color alone).\n- **Pricing:** 3 tiers; middle tier highlighted with emerald border, elevated shadow, and amber \"Most Popular\" badge; feature lists with check icons; one CTA button per tier; premium tier may use `--accent-premium` accents.\n- **FAQ:** accordion — each item is a `\u003Cbutton>` (`aria-expanded`, `aria-controls`) plus a panel; chevron Material Symbol rotates; smooth height transition; fully keyboard operable.\n- **Final CTA:** full-bleed section with curved organic `clip-path` edges, headline, and the email capture form (2.3) or a CTA that opens the modal (2.4).\n- **Footer:** brand block, 2–3 secondary link columns, social icon links (Material Symbols with `aria-label`s), copyright line; every link has hover and `:focus-visible` states.\n\n---\n\n## 3. CORE UX & MICRO-INTERACTION RULES\n\n- **Responsive by default:** fluid sizing, `clamp()` typography, zero horizontal overflow at every breakpoint.\n- **Smooth animations:** `transition: var(--transition-normal) var(--ease-standard)` on all state changes. **`prefers-reduced-motion: reduce` must disable leaf sway, blob morphing, and scroll reveals** — all content remains fully visible with no motion.\n- **Accessibility (a11y):** ≥ 4.5:1 text contrast in both Light and Dark modes; never rely on color alone to communicate state; semantic HTML5 (`header`, `nav`, `main`, `section`, `article`, `footer`); correct ARIA roles\u002Flabels on the accordion, modal, theme toggle, and mobile dropdown; logical DOM\u002Ffocus order; full keyboard operability (no mouse-only interactions); `aria-live` regions for form errors, toasts, and loading feedback.\n- **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.\n- **Destructive actions:** `.btn--danger` must be visually distinct in both light and dark themes.\n- **Scroll reveals:** `IntersectionObserver` adds `.is-visible` (opacity + translateY, staggered) — implemented as progressive enhancement so all content is visible without JavaScript.\n\n---\n\n## 4. DELIVERABLE & OUTPUT FORMAT\n\n- **File structure:** separate `index.html`, `style.css`, and `script.js`. No inline `\u003Cscript>` blocks beyond a single deferred entry-point reference to `script.js`; no inline styles; no inline event handlers (`addEventListener` only).\n- **Naming convention:** BEM consistently across the entire deliverable (`.card`, `.card__title`, `.card--featured`, `.btn--primary`) — never mix conventions.\n- **`script.js` responsibilities:** theme toggle + `localStorage` persistence, mobile navigation, FAQ accordion, modal with focus trap, form validation with loading\u002Fsuccess states + toast, and IntersectionObserver reveals. No console errors; the page degrades gracefully without JavaScript.\n- **No unrequested placeholders:** no lorem ipsum — write realistic English copy per Section 0 for every section; placeholders are permitted only where content was genuinely left unspecified.\n- Generate the complete final code for all files immediately, on the first attempt.\n",1791954989656]
