## 1. STRICT ARCHITECTURE RULES

### 1.1 CSS-First Architecture & Zero Inline CSS
- All styling must live in a dedicated `style.css` file. **The `style="..."` attribute is forbidden in HTML.**
- Target all design properties, layouts, and states exclusively via class or ID selectors.
- HTML must remain semantic and clean (`header`, `main`, `section`, `article`, `footer`, `nav`) — changing the site's look must only require editing the CSS file.

### 1.2 CSS Variables & Theme Tokens
Define all visual tokens in `:root`:
- **Colors:** `--primary: #A83E36` (accent red), `--secondary: #C5A065` (gold), `--bg-primary: #F3EAD3` (parchment), `--bg-secondary: #EFE3C8`, `--text-primary: #3E2F26`, `--text-secondary: #6B5544`, `--text-success: #7DA37D` (sage green), `--text-error: #A83E36`, `--border-default: #C5A065`, `--border-error: #A83E36`, `--border-success: #7DA37D`.
- **Supporting palette tokens:** `--sage: #7DA37D`, `--rose: #D48C8C`, `--gold: #C5A065`.
- **Contrast pairing:** Every background token must pair with a text token meeting WCAG AA contrast. Dark text (`#3E2F26`) on parchment backgrounds; light text (`#F3EAD3`) on dark backgrounds (e.g., footer in deep ink `#3E2F26` with `#F3EAD3` text).
- **Shape & depth:** `--radius-sm: 2px`, `--radius-md: 4px`, `--radius-lg: 8px` (keep radii small — this era favors sharp, ornamental corners), `--shadow-sm`, `--shadow-md` (soft, warm-toned shadows like `0 4px 12px rgba(62,47,38,0.15)`).
- **Spacing & motion:** `--spacing-gap: 1.5rem`, `--transition-fast: 0.15s`, `--transition-normal: 0.3s`, `--ease-standard: cubic-bezier(0.25, 0.8, 0.25, 1)`.
- **Elevation:** `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`.

### 1.3 Dark Mode Support
- Although the source spec is light-mode-only, **dark mode must still be defined**: provide tokens under `@media (prefers-color-scheme: dark)` and a `.dark` class — e.g., `--bg-primary: #2B211B` (aged dark leather), `--bg-secondary: #3E2F26`, `--text-primary: #F3EAD3`, `--text-secondary: #D8C9A8`, `--primary: #D48C8C`, `--secondary: #C5A065`, borders in muted gold `#8A744A`.
- Theme choice must persist via `localStorage`, falling back to `prefers-color-scheme` on first visit. Include a visible toggle button with correct `aria-pressed` and `aria-label` states, styled as an ornamental gold-framed control.

### 1.4 Flexbox Layout & Mobile-First
- Build all layout structures with Flexbox. **Every flex container must default to `align-items: center`** unless explicitly justified (e.g., testimonial cards with top-aligned text).
- Mobile-first: hero content, feature card grid, pricing tiers, and footer link columns must stack into single columns on small viewports. **No horizontal scrolling at any breakpoint.**

### 1.5 Framework
- Use Tailwind CSS via CDN, with all custom theme styling driven through `@layer` / `@apply` directives in `style.css`, mapping utilities back to CSS variables and reusable classes (`.btn`, `.card`, `.input-group`, `.section-title`, `.ribbon-banner`).

### 1.6 Typography & Icons (Google Fonts Mandatory)
- **Fonts:** Load Google Fonts — `Cinzel Decorative` for display headings (bind to `--font-display`), `Cormorant Garamond` for body text (bind to `--font-base`), and `Great Vibes` for ornamental accents/signatures.
- **Icons:** Use Google Material Symbols only. **Inline SVGs and local icon files are forbidden.**

## 2. THEME-SPECIFIC VISUAL DIRECTION

Recreate the Belle Époque lithograph aesthetic:
- **Backgrounds:** Parchment `#F3EAD3` with subtle paper texture via CSS gradients (e.g., layered `radial-gradient` washes simulating watercolor and vignette edges — `box-shadow: inset 0 0 20px rgba(0,0,0,0.1)` on section frames).
- **Ornamental borders:** Fine double-line borders in gold `#C5A065` and accent red `#A83E36` around cards and sections, simulating lithograph frames. Use CSS `border-image` or layered pseudo-element borders for ornamental corner flourishes.
- **Ribbon banners:** Section headings styled as ornamental ribbon banners using CSS clip-path/pseudo-elements in `--primary` or `--sage` with `--bg-primary` text.
- **Floral ornamentation:** Simulate Art Nouveau floral borders with CSS-only decorative elements (repeating gradients, pseudo-element flourishes) — no external images required; if imagery is used, use only free, hotlinkable placeholder sources with descriptive alt text.
- **Vignette & hatching:** Apply inset vignette shadows on cards and hero frames; use fine `repeating-linear-gradient` overlays at low opacity to suggest ink hatching.
- **Hero:** Full-width framed composition with the display font, an ornamental ribbon subtitle, and dual CTAs (primary red, secondary gold-outlined).

## 3. COMPONENT SPECIFICATIONS

### 3.1 Buttons (`.btn`, `.btn-primary`, `.btn-secondary`, `.btn-danger`)
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` — minimum touch target 44×44px. Primary: `--primary` background with `--bg-primary` text; Secondary: transparent with `--secondary` gold border.
- **Hover:** Brightness shift + shadow deepening, `cursor: pointer`.
- **Focus:** Distinct gold focus ring (`outline`/`box-shadow` using `--secondary`) for keyboard navigation.
- **Active:** `transform: scale(0.97)`.
- **Loading:** Disables interaction, prevents double-clicks, shows an animated Google Material Symbol spinner without changing button dimensions.
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Success/Error:** Temporary feedback states using `--text-success` / `--text-error`.

### 3.2 Cards (`.card`)
- **Default:** Flexbox layout, `--bg-secondary` parchment surface, ornamental gold border, subtle elevation.
- **Hover:** `transform: translateY(-2px)` + shadow shift.
- **Focus-within:** Gold border highlight when a child link/button is focused.
- **Loading:** CSS shimmer skeleton animation (parchment-toned) that prevents layout jumps.
- **Empty State:** Google Material Symbol icon + guidance text fallback.

### 3.3 Forms & Inputs (`.input-group`)
- **States:** Empty, Focused (gold outline ring), Filled, Valid (sage-green border + check icon), Invalid (`--border-error`, error text, error icon), Disabled, Read-only.
- **Structure:** Flex container wrapping `<label>`, `<input>`, and a dedicated error feedback element with `aria-live="polite"`.
- Apply to the Final CTA email capture and any FAQ search field.

### 3.4 FAQ Accordion
- Use `<details>`/`<summary>` or ARIA-compliant custom disclosure. Animated open/close via CSS transitions, keyboard operable, ornamental gold dividers between items, Material Symbols expand/collapse indicator.

### 3.5 Pricing Tiers
- Three `.card` tiers; middle tier visually elevated (larger scale/ornate frame, "Most Cherished" ribbon). Each tier: name, price, feature list with Material Symbol check marks, CTA button.

### 3.6 Testimonials
- Cards with quote styling in `Great Vibes` or italic `Cormorant Garamond`, attribution, sage/rose ornamental accents.

## 4. GLOBAL UX & ACCESSIBILITY

- **Responsive by default:** fluid sizing, breakpoints at ~768px and ~480px, zero horizontal overflow.
- **Animations:** `transition: var(--transition-normal)` on all state changes; fully respect `prefers-reduced-motion`.
- **Accessibility:** WCAG AA contrast in both light and dark modes; never rely on color alone for state; semantic HTML5 throughout; correct ARIA roles/labels; logical focus order; full keyboard operability; `aria-live` regions for form feedback and dynamic states.
- **Visual feedback:** Every click, hover, and submission triggers a visible state change.
- **Destructive actions:** `.btn-danger` must be visually distinct in both themes.

## 5. DELIVERABLES

- **Files:** Separate `index.html`, `style.css`, `script.js`. No inline `<script>` blocks beyond a single deferred entry-point reference.
- **Naming:** One consistent convention (BEM or fixed utility set) across the entire deliverable — never mix.
- **Copy:** Write all user-facing copy in **English**, in an elegant, refined Belle Époque voice appropriate to a Cultural & Heritage product (e.g., museum membership, heritage experience, or artisan atelier — choose one coherent concept and carry it through every section). No lorem ipsum.
- **Content completeness:** All eight sections fully populated with realistic copy, prices, testimonials, and at least 5 FAQ items.
