## 0. THEME BRIEF & DESIGN DIRECTION

**Mood keywords:** handmade furniture, Brazilian design, comfort, authentic, crafted, natural materials, robust, unique, cozy, inviting.

**Visual language:**
- Wood, leather, and straw textures rendered in UI elements — built **procedurally in pure CSS** (layered `repeating-linear-gradient` / `radial-gradient` patterns). Never as external image files.
- Robust serif display typography paired with an organic sans-serif body.
- Furniture photography in cozy settings (placeholder images only, per §4).
- Hover micro-interactions that highlight material texture or detail.
- Smooth "assembly" section transitions: elements enter the viewport as pieces settling into place (staggered translate + slight rotate easing to rest).

**Source CSS technicals to honor:** `border-radius: 8px` on contained/interactive elements; default borders `1px solid #D2B48C`; section-level transitions at `0.6s ease-in-out`; three required theme classes: `.wood-texture-bg`, `.leather-accent`, `.furniture-card-crafted`.

**Sections (in build order):** Sticky header (hosts theme toggle + anchor nav) → Hero → Features (3 cards) → How It Works (3 steps) → Testimonials → Pricing (3 tiers) → FAQ (accordion) → Final CTA (email capture form) → Footer (secondary links).

**Copy language:** All user-facing copy — headings, body, labels, buttons, prices, FAQ answers, microcopy — must be written in **English**. The brand name is a proper noun and may be Portuguese-inspired; everything else is English. Write realistic, specific, on-brand copy. Lorem ipsum is prohibited.

## 1. STRICT RULES & ARCHITECTURE

**1.1 CSS-First Architecture & Zero Inline CSS**
- All styling lives in `style.css`. The `style="..."` attribute is forbidden anywhere in the HTML.
- All design properties, layout rules, and states are targeted via class/ID selectors only.
- HTML remains clean, semantic, and styling-agnostic — re-theming the site must require touching only the CSS file.

**1.2 CSS Variables & Theme Tokens** — define in `:root` (light) and override in the dark scope (§1.3). Required tokens:

| Token | Light Value | Dark Value ("Evening Workshop") |
|---|---|---|
| `--primary` | `#8B4513` (Wood Brown) | `#CE8B4F` |
| `--secondary` | `#CC5500` (Burnt Orange) | `#E8761F` |
| `--secondary-deep` | `#A34300` (accessible orange for small text/links) | `#F09A52` |
| `--bg-primary` | `#FBF6EE` (warm cream — **never `#FFFFFF`**; any near-white surface uses `#FFFDF8` or `#fefefe`) | `#1E1710` |
| `--bg-secondary` | `#F5DEB3` (Straw Beige) | `#2A2118` |
| `--text-primary` | `#3B2A1A` (espresso) | `#F5DEB3` |
| `--text-secondary` | `#7A5C3E` (warm taupe) | `#C9B896` |
| `--text-success` | `#4E701D` (darkened olive — raw `#6B8E23` fails text contrast; use it only decoratively) | `#A9C46C` |
| `--text-error` | `#A93226` | `#E5837A` |
| `--border-default` | `#D2B48C` (tan, always `1px solid`) | `#4A3A28` |
| `--border-success` / `--border-error` | `#4E701D` / `#A93226` | `#A9C46C` / `#E5837A` |
| `--accent-olive` / `--accent-straw` / `--accent-deep-blue` / `--accent-concrete` / `--accent-ink` | `#6B8E23` / `#F5DEB3` / `#001F3F` / `#A9A9A9` / `#14100C` (warm near-black, replaces `#000000`) | same hues, adjusted for dark surfaces |

- Also define: `--radius-sm: 6px`, `--radius-md: 8px`, `--radius-lg: 20px`; `--shadow-sm` / `--shadow-md` (warm-tinted, e.g., `rgba(59,42,26,0.08/0.16)`); `--spacing-gap: 1.5rem` plus a section-padding token; `--transition-fast: 0.25s ease-in-out` (hover/press feedback), `--transition-normal: 0.6s ease-in-out` (section-level, per source spec), `--ease-standard: ease-in-out`; `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`; `--font-display: "Playfair Display", serif`, `--font-base: "Nunito Sans", sans-serif`.
- **Contrast pairing rule:** every light background token pairs with a dark text token and vice versa — in both themes. Verify ≥ 4.5:1 for body text, ≥ 3:1 for large text and UI borders. If `#CC5500` fill with light text falls below 4.5:1 at the chosen size, use `--secondary-deep` for that state.

**1.3 Mandatory Dark Mode**
- **Exception note:** the source style spec listed dark mode as "No" — dark mode is nonetheless a mandatory architectural requirement. Implement it as a warm "evening workshop" variant (deep browns, straw-tinted text) that preserves the cozy mood.
- Provide dark tokens under both `@media (prefers-color-scheme: dark)` and a `.dark` class on `<html>`; background/text variables must switch with zero HTML restructuring.
- Persistence: store the user's choice in `localStorage`; fall back to `prefers-color-scheme` on first visit; apply the stored preference as the first action of the entry script to minimize flash.
- A visible toggle button in the header with Google Material Symbols (`light_mode` / `dark_mode`), correct `aria-pressed` and `aria-label` state.

**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 CSS comment.
- Mobile-first: rows convert to columns at breakpoints; **zero horizontal scrolling** at any viewport from 320px up.

**1.5 Framework Default**
- Use clean custom CSS in `style.css` as the styling engine, optionally organized into Tailwind-style `@layer` blocks. If Tailwind is used, utilities may only handle layout/spacing — all colors, fonts, radii, and shadows must come from CSS variables or semantic classes (`.btn`, `.card`, `.input-group`). Never hardcode hex values in utility classes.

**1.6 Typography & Icons (Google Only)**
- Google Fonts via `<link>` with preconnect: **"Playfair Display"** (600/700) for display headings; **"Nunito Sans"** (400/600/700) for body.
- Icons: **Google Material Symbols (Rounded style)** via the official stylesheet, ligature names. Inline SVGs and local icon files are forbidden. Social links use text labels or available symbols (e.g., `alternate_email`, `call`) — never inline SVG brand logos.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Buttons** — `.btn`, `.btn--primary` (burnt orange fill), `.btn--secondary` (wood-brown outline), `.btn--danger` (visually distinct in both themes), `.btn--ghost`:
- Default: `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px, `--radius-md`.
- Hover: brightness/shadow shift, `cursor: pointer`.
- Focus: distinct visible ring via `outline`/`box-shadow` using `--secondary` — never remove outlines.
- Active: `transform: scale(0.97)`.
- Loading (`.is-loading`): interactions disabled, double-click prevented, CSS border spinner or animated Material Symbol, dimensions unchanged.
- Disabled: `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- Success/Error: temporary feedback styles driven by `--text-success` / `--text-error`.

**2.2 Cards** — `.furniture-card-crafted` (required exact class name) for Features; reuse the pattern for Testimonials and Pricing:
- Default: flex layout, `--bg-secondary` surface, `1px solid var(--border-default)`, `--radius-lg`, `--shadow-sm`.
- Hover: `translateY(-2px)` + `--shadow-md` + a **texture-highlight micro-interaction** (e.g., the card's CSS wood-grain layer intensifies, or a corner "material swatch" chip fades in).
- Focus-within: border shifts to `--secondary` when a child link/button is focused.
- Loading: skeleton shimmer keyframes defined for image-bearing cards to prevent layout jumps.
- Empty state: structured fallback with a Material Symbol and guidance text, if any card list can render empty.

**2.3 Form & Input** (Final CTA email capture, `.input-group`):
- Structure: flex container wrapping a `<label>`, an `<input type="email">`, and a dedicated message container with `aria-live="polite"`.
- States: empty, focused (outline ring), filled, valid (`--border-success` + check symbol), invalid (`--border-error`, `--text-error` message, error symbol), disabled, read-only.

**2.4 Modal / Popup** (applies to any overlay the build introduces; the FAQ must be an accordion, not modals):
- States: opening, open, loading, success/error, closing — all CSS-transitioned.
- Centered flex overlay (`align-items: center`), backdrop, Material Symbol close button, keyboard focus trap, `Esc` and backdrop-click close, `role="dialog"` + `aria-modal`.

## 3. CORE UX & MICRO-INTERACTION RULES

- Responsive by default; fluid sizing; no horizontal overflow.
- Smooth CSS transitions on all state changes via the token scale; **respect `prefers-reduced-motion`** (disable transforms and reveals; keep content fully visible).
- Accessibility: AA contrast in both themes; never rely on color alone (pair icons/text with every state); semantic HTML5 landmarks; correct ARIA on custom widgets; logical DOM/focus order; full keyboard operability; `aria-live` regions for dynamic feedback (form errors, success confirmations, loading).
- Every click, hover, and submission triggers visible feedback.
- **"Assembly" reveal system:** elements with a reveal class start hidden (`opacity: 0; translateY(24px);` optional `rotate(1deg)`); an IntersectionObserver adds `.is-visible`; staggered `transition-delay` per child so sections feel like pieces settling into place. Disabled under reduced motion.

---

## 4. DELIVERABLES & OUTPUT FORMAT

- Separate `index.html`, `style.css`, `script.js`. No inline styles; no inline scripts beyond the single `<script src="script.js" defer></script>` entry point.
- Naming: **BEM (Block__Element--Modifier) exclusively** — never mix conventions. `.wood-texture-bg`, `.leather-accent`, `.furniture-card-crafted` are BEM blocks and must exist with exactly these names.
- Photographic placeholders only via `https://picsum.photos/seed/<descriptive-seed>/<width>/<height>.jpg` with meaningful alt text; all textures are pure CSS.
- No lorem ipsum: write real, specific English copy for every heading, paragraph, button, price, and FAQ answer.

---

## 5. SECTION-BY-SECTION BUILD SPECIFICATION

**5.1 Sticky Header** — brand wordmark (Playfair Display), anchor nav (Features, Process, Testimonials, Pricing, FAQ), theme toggle; wood-texture bottom border; on mobile, a Material Symbol `menu` button opens a dropdown panel (`--z-dropdown`) with correct `aria-expanded` and keyboard support.

**5.2 Hero** — single `<h1>` + subheadline, primary CTA (burnt orange) + secondary CTA (outline), hero photo (picsum, cozy furniture setting), trust chips (e.g., "Solid hardwood · Full-grain leather · Made to order"), decorative `.wood-texture-bg` band; assembly reveal on load.

**5.3 Features — 3 `.furniture-card-crafted` cards** — e.g., "Solid Hardwood," "Full-Grain Leather," "Woven Straw"; each with a Material Symbol, title, 2–3 sentence description, and the texture-highlight hover.

**5.4 How It Works — 3 steps** — numbered 01/02/03 with a connecting rule, e.g., "Choose & Customize" → "We Handcraft It" → "White-Glove Delivery"; staggered assembly reveal.

**5.5 Testimonials — 3 quotes** — picsum avatar, five-star Material Symbol rating, quote, name + city (e.g., "Mariana C. — São Paulo, Brazil").

**5.6 Pricing — 3 tiers** — e.g., "The Essential Piece" / "The Signature Room" / "The Heritage Home" with realistic USD prices, feature lists, and a CTA per tier; middle tier badged "Most Loved" with distinct border/elevation; equal-height flex cards.

**5.7 FAQ — accessible accordion** — 5–6 real questions (materials, lead time, delivery, care, returns); `<button aria-expanded>` + region (or styled `<details>/<summary>`), animated open/close, rotating `expand_more` symbol, fully keyboard operable.

**5.8 Final CTA** — full-bleed band on `--accent-deep-blue` with straw text (verify the pairing in dark mode), headline, and the email capture form per §2.3 with loading → success state and an `aria-live` confirmation message.

**5.9 Footer** — deep blue background, straw text, brand blurb, secondary link columns (About, Care Guide, Shipping & Delivery, Returns, Privacy, Terms), contact line, social links, copyright; all links visibly focus-styled.
