## 1. STRICT RULES & ARCHITECTURE

**1.1 CSS-First Architecture & Zero Inline CSS**
* Keep all styling strictly inside a dedicated `style.css` file. The `style="..."` attribute is **forbidden** anywhere in the HTML.
* All design properties, layout rules, and states must be targeted via class or ID selectors only.
* HTML must remain clean, semantic, and agnostic of visual styling — changing the site's look must require modifying only the CSS file, never the markup.

**1.2 CSS Variables & Theme Tokens**
Store all visual tokens in `:root` and override them in the dark theme. Mandatory tokens: `--primary`, `--secondary`, `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default`, `--border-error`, `--border-success`, `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`, `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`, `--z-dropdown`, `--z-modal`, `--z-toast`, plus `--font-base` and `--font-display`.

* **Light mode values:** `--primary: #8B4513` (Earth Brown); `--secondary: #6B8E23` (Olive Green); accent tokens `--accent: #CC5500` (Burnt Orange), `--accent-sky: #87CEEB`, `--accent-coral: #FF6F61`, `--accent-ochre: #CC7722`; `--bg-primary: #F5DEB3` (Sand Beige page canvas); `--bg-secondary: #FEFEFE` (card surfaces); `--text-primary: #3E2723` (deep espresso brown); `--text-secondary: #8B4513`; `--text-success: #556B2F` (darkened olive, AA-safe on sand); `--text-error: #B03A2E` (deepened coral, AA-safe on sand); `--border-default: rgba(139, 69, 19, 0.25)`; `--border-error: #B03A2E`; `--border-success: #556B2F`.
* **Exception clause:** The source spec requests `background: #FFFFFF` — pure white is forbidden; use `#FEFEFE` for near-white surfaces and the Sand Beige `#F5DEB3` as the themed page canvas.
* **Contrast pairing:** Every light background token must pair with a dark text token and every dark background token with a light text token — enforce this in both themes. Verify WCAG AA (4.5:1 body, 3:1 large text) for every text/background combination.
* **Transitions:** `--transition-normal: 0.7s ease-in-out` (per source spec, reserved for section/collage reveals); `--transition-fast: 0.2s`; `--ease-standard: ease-in-out`. Micro-interactions (hover/focus) must use `--transition-fast` for responsiveness.
* **Elevation:** `--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 selector. Suggested values: `--bg-primary: #1E130C`, `--bg-secondary: #2A1B10`, `--text-primary: #F5DEB3`, `--text-secondary: #CFA97A`, `--text-success: #A3C255`, `--text-error: #FF6F61`, `--border-default: rgba(245, 222, 179, 0.2)`. Keep `--primary` fills at `#8B4513` (sand text passes AA on it) and lighten primary-colored text/icons in dark mode for contrast.
* Theme switching must work purely through CSS variables — no HTML restructuring. Persist the user's choice via `localStorage`, falling back to `prefers-color-scheme` on first visit. Provide a visible toggle button using Material Symbols (`light_mode`/`dark_mode`) with correct `aria-pressed` and `aria-label` state.
* **Exception clause:** Although the source style spec may read as light-only, full dark mode is a mandatory architectural requirement and must be fully implemented.

**1.4 Flexbox Layout & Mobile-First Alignment**
* Build every layout structure with Flexbox. Every flex container must default to `align-items: center` unless an explicitly justified exception exists (document the exception in a CSS comment).
* All flex layouts must be mobile-responsive out of the box: rows convert to columns below 768px, content wraps, and horizontal scrolling is impossible at any viewport width.

**1.5 Framework Default & Tailwind CSS Integration**
* Use Tailwind CSS (CDN acceptable) or clean custom CSS driven by `@layer`/`@apply`. All utility classes must map back to CSS variables or generic reusable class names (`.btn`, `.card`, `.input-group`). Never hardcode hex values in utilities — route every color through a variable.

**1.6 Typography & Icons (Google Fonts Mandatory)**
* Load Google Fonts via `<link>` tags: **"Dancing Script"** bound to `--font-display` (hero headline, section titles, brand wordmark, price figures only — never body text, for legibility) and a readable sans-serif such as **"Poppins"** bound to `--font-base` for all body copy.
* Use **Google Material Symbols** for every icon, wrapped in a `.regional-icon` class. Raw inline SVGs, local icon files, and emoji-as-icons are all forbidden.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Button Component Requirements**
Style all states via CSS classes (BEM: `.btn`, `.btn--primary`, `.btn--secondary`, `.btn--accent`, `.btn--danger`):
* **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Variants: primary = Earth Brown fill + Sand text; secondary = darkened olive `#556B2F` fill + `#FEFEFE` text; accent = Burnt Orange fill + `#FEFEFE` text; danger = Coral `#FF6F61` fill + `#1E130C` text (visually distinct in both themes).
* **Hover:** brightness/shadow shift with `cursor: pointer`.
* **Focus:** distinct focus ring via `outline`/`box-shadow` using CSS variables, keyboard-navigable.
* **Active/Pressed:** `transform: scale(0.97)`.
* **Loading:** disables interactions, prevents double-clicks, renders a rotating Material Symbol (`progress_activity`) spinner without changing button dimensions; set `aria-busy`.
* **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
* **Success/Error:** temporary feedback styles driven by `--text-success`/`--text-error`.

**2.2 Card Component Requirements**
Apply to feature, testimonial, and pricing cards:
* **Default:** flexible Flexbox layout, `--bg-secondary` surface, subtle `--border-default` border, elevation via `--shadow-sm`.
* **Hover:** `transform: translateY(-2px)` plus shadow shift to `--shadow-md`.
* **Focus-within:** card border highlights when a child link/button receives focus.
* **Loading (Skeleton):** define a `.skeleton` shimmer keyframe animation in CSS to prevent layout jumps.
* **Empty State:** define a structured fallback pattern featuring a Material Icon and clear guidance text.

**2.3 Form & Input Requirements**
Build the newsletter signup as a flex `.input-group` wrapping a `<label>`, an `<input>`, and a dedicated error feedback container with `aria-live="polite"`. Account for all states via CSS: empty, focused (outline ring using `--accent`), filled, valid (`--border-success` + `check_circle` icon), invalid (`--border-error`, `--text-error`, `error` icon), disabled, and read-only.

**2.4 Accordion & Overlay Requirements**
* **FAQ Accordion:** implement the ARIA pattern — `<button aria-expanded>` controlling a panel via `aria-controls`, animated open/close with CSS transitions, a Material Symbol `expand_more` chevron rotating 180°, fully keyboard operable.
* **Modal/Popup:** no modals are required for this page; if any overlay is introduced, it must be a centered flex container with backdrop, Material Icon close button, focus trapping, `Esc`/overlay-click closing, and `--z-modal` stacking.

**2.5 Theme-Specific Visual Components**
* **`.regional-mosaic`:** a CSS Grid/flex-wrap mosaic of product image tiles with varied spans and slight rotations (`transform: rotate(-2deg)`/`rotate(1.5deg)`) evoking a hand-pinned craft collage, framed with sand-toned borders. Images must use seeded `https://picsum.photos/seed/<descriptive-seed>/<w>/<h>` URLs with English alt text. On hover/focus, each tile lifts and reveals an origin label.
* **`.regional-icon`:** circular flex badge (`align-items: center; justify-content: center`) containing a Material Symbol representing each region's culture (e.g., `forest` for the Amazon North, `wb_sunny` for the Northeast sertão, `ac_unit` for the South).
* **Origin/Story Hover Micro-interaction:** every product/feature card contains a `.card__origin` panel (region name + one-line artisan story) revealed on `:hover` **and** `:focus-within` via opacity/transform transitions, so keyboard users get the identical experience.
* **`.collage-assembly-transition`:** decorative collage seams between sections — overlapping rotated strips/blocks in Earth Brown, Olive, Burnt Orange, and Sky Blue — plus scroll-triggered section reveals (fade + slide, `transition: all 0.7s ease-in-out`) activated by an IntersectionObserver adding `.is-visible`.

## 3. LANDING PAGE SECTION SPECIFICATION

**3.1 Header (sticky):** `#FEFEFE` background (light) with `#8B4513` text and `border-bottom: 1px solid #CC5500` per source spec; Dancing Script brand wordmark; anchor nav links (Features, How It Works, Testimonials, Pricing, FAQ) with burnt-orange hover underline; theme toggle; hamburger (`menu` icon) toggling a mobile dropdown panel at `--z-dropdown`, closable via `Esc`.

**3.2 Hero:** two-column flex (row desktop → column mobile, `align-items: center`). Left: eyebrow badge with `.regional-icon`, H1 in Dancing Script (e.g., "From the Amazon to the Pampas — Authentic Brazil, Delivered"), subhead, dual CTAs (`.btn--accent` "Shop Regional Crafts" + `.btn--secondary` "Explore the Regions"), trust row (5 regions · 120+ artisans). Right: `.regional-mosaic` of 4–6 product tiles with hover origin labels.

**3.3 Features — 3 cards:** "Regional Treasures" — one card per region (North, Northeast, South), each with `.regional-icon`, title, description of signature goods (açaí & woven baskets; ceramics & *renda de bilro* lace; wool ponchos & *chimarrão*), a "Discover [Region]" link, and the `.card__origin` hover story panel. Row → column on mobile.

**3.4 How It Works — 3 steps:** horizontal flex with numbered badges (01/02/03), a dashed connecting line (hidden on mobile), and Material icons (`explore` → `local_shipping` → `inventory_2`): Choose Your Region → Artisans Craft & Pack → Delivered with Its Story. Staggered scroll-in animation.

**3.5 Testimonials:** 3 testimonial cards with quote, 5-star rating via Material `star` icons, author name, region/city, and seeded picsum avatar.

**3.6 Pricing — 3 tiers:** `.card--pricing` for "Sertão Box" ($29/mo), "Vale Dourado" ($59/mo — featured: Burnt Orange border, "Most Loved" badge, elevated shadow/scale), "Heritage Collector" ($99/mo). Prices in Dancing Script; feature lists with `check_circle` icons; one `.btn` per tier (featured gets `.btn--accent`).

**3.7 FAQ:** 5–6 questions (shipping, fair-trade artisan payment, regions covered, customization, returns, cancellation) using the ARIA accordion from 2.4.

**3.8 Final CTA:** full-bleed Earth Brown band with Sand Beige text in both themes, Dancing Script headline ("Bring Brazil Home"), the newsletter `.input-group` + `.btn--accent`, and success/error feedback announced via `aria-live`.

**3.9 Footer:** brand column (Dancing Script wordmark + blurb), four secondary link groups (Shop, Regions, Company, Help — 12+ secondary links total), social icons as generic Material Symbols (`language`, `mail`, `rss_feed`) with `aria-label`s, and a copyright line — all AA-compliant in both themes.

## 4. CORE UX & MICRO-INTERACTION RULES

* **Responsive by default:** fluid sizing, breakpoints at 640/768/1024px, zero horizontal overflow.
* **Smooth animations:** CSS transitions on all state changes; `--transition-normal` (0.7s) for section/collage reveals, `--transition-fast` for hover/focus. `prefers-reduced-motion` must disable rotations, transforms, and scroll animations (opacity-only fallbacks).
* **Accessibility:** AA contrast in light and dark modes; never rely on color alone (pair every error/success with an icon + text); semantic HTML5 landmarks (`header`, `nav`, `main`, `section` with `aria-labelledby`, `footer`); a skip link; logical focus order; full keyboard operability for menu, accordion, toggle, and forms; `aria-live` regions for all dynamic feedback.
* **Mandatory visual feedback:** every click, hover, and submission triggers a visible state change.
* **Destructive actions:** `.btn--danger` must be visually distinct in both themes.

## 5. DELIVERABLE & OUTPUT FORMAT

* **Files:** separate `index.html`, `style.css`, and `script.js`. No inline `<script>` blocks beyond a single deferred `script.js` reference. Zero inline styles.
* **Naming:** BEM convention exclusively (`card__origin`, `card--pricing`, `btn--accent`, `regional-mosaic__tile`) — never mix conventions.
* **Copy:** write real, themed English copy for every section — lorem ipsum is prohibited. Seeded picsum placeholders are permitted only for imagery.
* **Completeness:** deliver the full, runnable landing page on the first attempt — all eight sections, both themes, all component states, and all interactions functional.
