## 0. PROJECT BRIEF, THEME & PAGE SPECIFICATION

**0.1 Theme Identity**
- **Name:** Adventurous Natural Tropicalism ("Tropicalismo Aventureiro Natural")
- **Type:** Adventurous, Natural, Engaging, Sustainable
- **Keywords:** ecotourism, travel agency, Brazil, adventurous, natural, engaging, sustainable, immersive, exploration, vibrant
- **Era:** 2026+ Sustainable Adventure
- **Light/Dark:** Full dual-theme support required (see 1.3)

**0.2 Color Palette (source values — map to tokens in 1.2)**
- **Primary:** Emerald Green `#2ECC40` · Turquoise Blue `#40E0D0` · Earth Brown `#8B4513` · Sun Yellow `#FFD700`
- **Secondary:** Burnt Orange `#CC5500` · Coral Red `#FF6F61` · Sand Beige `#F5DEB3` · White `#FFFFFF`

**0.3 Visual Effects (translated from source direction — mandatory)**
- Full-screen Brazilian natural landscape scenes in the hero (implementation per 0.5.1)
- Adventure-themed sans-serif typography (Montserrat, extra-bold headlines)
- UI elements shaped as leaves and mountains (asymmetric border-radius badges, clip-path section dividers)
- Hover micro-interactions with a landscape-detail "discovery" effect (per 3.5)
- Section transitions with a map "exploration"/"zoom" entrance effect (per 3.5)

**0.4 Copy Rules**
- Write real, adventurous, sustainability-forward English copy. No lorem ipsum. Active voice, invigorating tone (e.g., "Explore the wild heart of Brazil — one trail at a time").

**0.5 Required Page Structure (build in this order)**
- **0.5.1 Sticky Header + Hero (`.landscape-hero`):** Header is fixed/translucent (`backdrop-filter: blur`), flex with `align-items: center`, containing a leaf-icon logo + brand name, anchor nav (Features, How It Works, Pricing, FAQ), theme toggle (1.3), and a "Book a Trip" CTA. On mobile, nav collapses behind a hamburger (Material Symbol `menu`/`close`) with `aria-expanded`, Esc-to-close, and `--z-dropdown` stacking. Hero fills the viewport (`min-height: 100svh`) with a **CSS-composed Brazilian landscape** (layered gradients: turquoise→emerald sky, Sun Yellow sun disc, clip-path mountain silhouettes in Earth Brown/deep greens, leaf-shaped foreground). Content sits on a dark scrim guaranteeing ≥4.5:1 contrast in both themes: eyebrow label, single `<h1>`, supporting line, two CTAs (primary "Explore Our Tours" → `#pricing`; ghost "How It Works" → `#how-it-works`). Discovery hover reveals hidden landmark pins ("Amazon", "Pantanal", "Chapada Diamantina") fading in. Include a scroll-cue chevron (reduced-motion safe).
- **0.5.2 Features (`#features`) — 3 `.feature-card`:** Section heading pattern (eyebrow + `<h2>` + intro line, reused site-wide). Cards: "Sustainable Routes" (icon `eco`), "Local Expert Guides" (icon `hiking`), "Small-Group Immersion" (icon `groups`). Each has a `.leaf-mountain-element` icon badge, title, copy, and a hidden "discovery" detail line revealed on hover/focus-within (3.5).
- **0.5.3 How It Works (`#how-it-works`) — 3 steps:** "Choose Your Trail" (`map`), "Plan with a Local Expert" (`support_agent`), "Embark & Explore" (`explore`). Numbered leaf badges connected by a dashed trail line (pseudo-element); steps reveal with staggered exploration animation.
- **0.5.4 Testimonials (`#testimonials`) — 3 `.testimonial-card`:** Five `star` icons with `aria-label="Rated 5 out of 5 stars"`, quote, pure-CSS leaf-shaped avatar with initials (no external images), name + descriptor (e.g., "Marina — Wildlife Photographer").
- **0.5.5 Pricing (`#pricing`) — 3 `.pricing-card`:** "Explorer" $890/trip; "Adventurer" $1,490/trip (featured: Sun Yellow "Most Popular" badge, emphasized border/scale); "Expedition Leader" $2,890/trip. Feature lists with `check_circle` icons; per-card CTA (featured = primary, others = secondary) linking to `#final-cta`.
- **0.5.6 FAQ (`#faq`) — 5–6 `.faq-item`:** Real questions (sustainability practices, group sizes, difficulty levels, best season, cancellation policy, what's included). Accordion behavior per 2.5.
- **0.5.7 Final CTA (`#final-cta`):** Full-width band with emerald→turquoise gradient and mountain clip-path divider; `<h2>` "Ready for Your Next Expedition?"; email-capture `.input-group` ("Get your free Brazil eco-itinerary") + primary button with full form states (2.3); on valid submit: loading → success + `aria-live` confirmation.
- **0.5.8 Footer (`.site-footer`):** Brand block with one-line mission; secondary link columns — "Company" (About Us, Sustainability, Contact) and "Support" (FAQ, Privacy Policy, Terms of Service); social icons (Material Symbols) with `aria-label`s; copyright with dynamic year; tagline. All links have hover/focus states.

## 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 are targeted via class/ID selectors in `style.css`.
- **Minimal HTML Modifications:** HTML stays semantic and style-agnostic; re-theming must require CSS edits only.

**1.2 CSS Variables & Theme Tokens**
Store all tokens in `:root` (light) and override in `.dark`:
- **Colors (light):** `--primary: #2ECC40`; `--primary-deep: #228B22` (text-safe green per source spec); `--secondary: #40E0D0`; `--accent-sun: #FFD700`; `--accent-earth: #8B4513`; `--accent-burnt: #CC5500`; `--accent-coral: #FF6F61`; `--bg-primary: #FAF5EA` (warm sand off-white derived from Sand Beige — **not** pure white); `--bg-secondary: #FFFFFF`; `--bg-tertiary: #F5DEB3`; `--text-primary: #1E3329`; `--text-secondary: #5C4326`; `--text-success: #1E7A34`; `--text-error: #C0392B`; `--border-default: rgba(139,69,19,0.28)`; `--border-error: #C0392B`; `--border-success: #1E7A34`.
- **Colors (dark):** `--bg-primary: #0E211A`; `--bg-secondary: #163028`; `--bg-tertiary: #1F3D33`; `--text-primary: #F4F8EC`; `--text-secondary: #F5DEB3`; `--primary-deep: #7BE382` (remapped lighter so it stays text-safe on dark); `--text-success: #6FE87F`; `--text-error: #FF8A7A`; `--border-default: rgba(64,224,208,0.25)`; keep the vibrant accents (`#2ECC40`, `#40E0D0`, `#FFD700`), which pop on dark surfaces.
- **Contrast Pairing:** Every light background token pairs with a dark text token and vice versa — enforced in **both** themes. Vibrant hues (`#2ECC40`, `#FFD700`, `#FF6F61`) must never be used as text on light backgrounds (contrast failure); reserve them for fills/accents and dark-mode text. Verify ≥4.5:1 for all text in both themes.
- **Pure-White Exception Clause:** The source palette lists `#FFFFFF`; pure white is permitted **only** as a card/surface fill (`--bg-secondary`), never as the page-wide background; any other near-white need uses `#fefefe`.
- **Radius & Shadows:** `--radius-sm: 6px`; `--radius-md: 10px` (per source spec); `--radius-lg: 24px`; `--leaf-radius: 0 50% 0 50%` (leaf silhouette); `--shadow-sm: 0 2px 6px rgba(0,0,0,0.08)`; `--shadow-md: 0 6px 12px rgba(0,0,0,0.1)` (per source spec; deepen opacity in dark mode).
- **Spacing & Transitions:** `--spacing-gap: 1.5rem`; `--transition-fast: 0.25s var(--ease-standard)`; `--transition-normal: 0.6s var(--ease-standard)` (per source spec); `--ease-standard: ease-in-out`. Apply transitions to explicit properties (`color`, `background-color`, `border-color`, `box-shadow`, `transform`, `opacity`) rather than `all`, to avoid layout jank.
- **Elevation/Stacking:** `--z-dropdown: 100`; `--z-modal: 1000`; `--z-toast: 1100`.

**1.3 Mandatory Dark Mode Support**
- Define dark tokens under **both** `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`.
- Theme switching must swap variables seamlessly with zero HTML restructuring.
- Persist user choice via `localStorage` (key `theme-preference`), falling back to `prefers-color-scheme` on first visit. Provide a visible header toggle (Material Symbols `light_mode`/`dark_mode`) with correct `aria-pressed` and dynamic `aria-label` ("Switch to dark mode" / "Switch to light mode").

**1.4 Flexbox Layout & Mobile-First Alignment**
- Build all layout structures with Flexbox. Every flex container defaults to `align-items: center` unless an exception is explicitly justified in a code comment (e.g., stacked hero text).
- Mobile-first: single-column stacking on small viewports, multi-column rows at `≥768px`/`≥1024px`. No horizontal scrolling anywhere (`overflow-x` safe, fluid `clamp()` typography, `max-width: 100%` media).

**1.5 Framework Default & Tailwind CSS Integration**
- Use Tailwind CSS (CDN) for layout utilities, with all theme styling driven by the CSS variables above in `style.css` (optionally via `@layer`/`@apply`). Utility classes must map back to tokens or generic reusable classes: `.btn`, `.card`, `.input-group`.

**1.6 Typography & Icons (Google Fonts Mandatory)**
- **Text:** Load **Montserrat** from Google Fonts (weights 400/600/700/800/900) via `<link>`; bind to `--font-base`. Headlines use 800/900 for the adventurous feel; eyebrow labels use uppercase + letter-spacing.
- **Icons:** Google Material Symbols (Rounded) exclusively — **inline SVGs, local icon files, and emoji-as-icons are forbidden.** Suggested symbols: `eco`, `hiking`, `groups`, `map`, `explore`, `forest`, `star`, `check_circle`, `expand_more`, `arrow_forward`, `menu`, `close`.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Button Component (`.btn`, variants `.btn--primary`, `.btn--secondary`, `.btn--ghost`, `.btn--danger`)**
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px; `--radius-md`; bold weight. Primary = Emerald fill with **deep jungle ink text** (never white text on `#2ECC40` — contrast failure).
- **Hover:** brightness/shadow shift with `cursor: pointer`.
- **Focus:** distinct turquoise ring (`outline` via `--secondary`, 2px offset) visible in both themes.
- **Active/Pressed:** `transform: scale(0.97)`.
- **Loading (`.is-loading`):** blocks interaction and double-clicks, renders a CSS spinner or rotating Material Symbol without changing button dimensions; set `aria-busy="true"`.
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Success/Error (`.is-success` / `.is-error`):** temporary feedback driven by `--text-success` / `--text-error`.
- **`.btn--danger`:** Burnt Orange/Coral-based, visually distinct in both themes.

**2.2 Card Component (`.card`, `.feature-card`, `.pricing-card`, `.testimonial-card`)**
- **Default:** flexible flexbox layout, `--bg-secondary` fill, 1px `--border-default`, `--radius-md`, `--shadow-sm`.
- **Hover:** `transform: translateY(-2px)` + `--shadow-md` + discovery effect (3.5).
- **Focus-within:** border shifts to `--secondary` when a child link/button receives focus.
- **Loading (Skeleton):** define `.card--skeleton` shimmer keyframes in CSS for any dynamically loaded content.
- **Empty State:** define `.card--empty` with a Material Symbol and clear guidance text as a structured fallback.

**2.3 Form & Input (`.input-group`)**
- **Structure:** flex container wrapping `<label>`, `<input>`, and a dedicated error container (`<p class="input-group__error">`) linked via `aria-describedby`; errors announced in an `aria-live` region.
- **States (via classes/pseudo-classes):** empty, focused (turquoise ring), filled, valid (`.is-valid` — success border + `check_circle`), invalid (`.is-invalid` — error border, `--text-error` message + error icon), disabled, read-only. Never rely on color alone — pair borders with icons/text.

**2.4 Modal / Popup (`.modal`)**
- If any trigger opens one (e.g., a "Book a Trip" inquiry modal), include: centered flex overlay (`align-items: center`), backdrop, Material Symbol close button, keyboard focus trapping, Esc and overlay-click closing, CSS-animated opening/closing, and internal loading + success/error states. Stack at `--z-modal`.

**2.5 FAQ Accordion (`.faq-item`)**
- Each trigger is a `<button>` with `aria-expanded` and `aria-controls`; the panel uses `role="region"` + `aria-labelledby`; `expand_more` icon rotates 180° when open; open/close animated via CSS (grid-rows or max-height, `--transition-normal`); fully keyboard operable; JS only toggles classes/attributes.

## 3. CORE UX & MICRO-INTERACTION RULES

- **Responsive by Default:** fluid sizing, standard breakpoints, zero horizontal overflow.
- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; every animation respects `@media (prefers-reduced-motion: reduce)` (disable transforms/parallax/zoom; keep simple opacity).
- **Accessibility (a11y):** semantic HTML5 landmarks (`header`, `nav`, `main`, `section`, `footer`), a skip link, one `<h1>` with logical heading order, correct ARIA roles/labels on custom widgets, logical focus order, full keyboard operability (no mouse-only interactions), and `aria-live` regions for dynamic feedback (form errors, confirmations, loading).
- **Mandatory Visual Feedback:** every click, hover, and submission triggers a visible state change.
- **Destructive Actions:** any destructive control uses `.btn--danger`, distinct in both themes.
- **3.5 Theme Micro-Interactions (mandatory):**
  - **Discovery hover (`.discovery-hover-effect`):** hovering (and `:focus-within`, and `:active` for touch) reveals hidden landscape details — extra caption lines, icon swaps, or layered-scene shifts — via opacity/transform/max-height transitions. Keyboard and touch users must receive the same reveal.
  - **Exploration/zoom transitions (`.section--explore`):** sections begin at `scale(0.96)` + `opacity: 0`; an IntersectionObserver adds `.is-visible` to animate to `scale(1)` + `opacity: 1` over `--transition-normal`, with staggered delays for step/card groups. Hero layers may parallax subtly on scroll (disabled under reduced motion).
  - **Leaf/mountain shapes (`.leaf-mountain-element`):** leaf badges use `--leaf-radius`; mountain-shaped clip-path dividers separate key sections (after hero, before Final CTA), consistent in both themes.

---

## 4. DELIVERABLE & OUTPUT FORMAT

- **File Structure:** separate `index.html`, `style.css`, `script.js`. No inline `<script>` blocks beyond a single deferred entry-point reference (`<script src="script.js" defer>`). No inline styles.
- **Naming Convention:** BEM (`block__element--modifier`) consistently across the entire deliverable — never mix conventions. The source-specified classes `.landscape-hero`, `.leaf-mountain-element`, and `.discovery-hover-effect` must exist as BEM blocks/elements.
- **No Unrequested Placeholders:** write real English copy for every section per 0.5; placeholders are permitted only where content was genuinely unspecified.
- **Images:** prefer self-contained CSS-composed landscape scenes (gradients + clip-path). If external placeholder photos are used, they require descriptive `alt` text and a CSS gradient fallback. Nothing may break the layout offline.
- **Definition of Done:** both themes toggle and persist correctly; all component states from Section 2 are styled; all micro-interactions from 3.5 work with mouse, keyboard, and touch; no console errors; valid, semantic HTML.
