## 0. DESIGN BRIEF & THEME TOKENS

**0.1 Theme Identity**
- **Name:** Ancient Egyptian / Historical — Ancient, Ornamental, Symbolic, Timeless.
- **Keywords:** Papyrus, hieroglyphic, scholarly, timeless, mysterious, ornamental borders, flat profile figures, stone-carved, archaeological.
- **Visual Direction:** Papyrus background (`#FDF6E3`), hieroglyphic-style ornamental borders, flat profile figures (Egyptian frontalism: head in profile, torso frontal), ornamental frames, gold ochre accents, aged parchment texture, compartmentalized triptych layouts, stone-carved aesthetic.
- **Lighting Rule:** Flat illustration lighting — uniform illumination. **Absolutely no color gradients** anywhere (no linear/radial color blends for depth, lighting, or decoration). Depth is expressed through flat offset "carved" shadows, borders, and pattern layers only.
- **Light/Dark:** Light-first theme ("Papyrus Day" default). Dark mode ("Tomb Night") is **mandatory and fully functional** per Section 1.3.
- **Product Concept:** Invent one coherent, plausible product concept consistent with the scholarly/archaeological theme (e.g., an interactive hieroglyph-learning platform or digital papyrus archive) and write ALL copy around it. All user-facing copy must be in **English**.

**0.2 Required Sections (in this exact order)**
1. Sticky Header (logo, anchor nav, theme toggle, mobile menu)
2. Hero (headline, subheadline, primary + secondary CTA, decorative flat profile figure)
3. Features — 3 cards in a triptych layout
4. How It Works — 3 steps in a triptych layout
5. Testimonials — 3 quotes
6. Pricing — 3 tiers (middle tier featured)
7. FAQ — accordion, 4–6 items
8. Final CTA (with newsletter signup form)
9. Footer with secondary links (About, Contact, Privacy, Terms + icon links)

**0.3 Color Tokens — Light Mode "Papyrus Day" (default, in `:root`)**
- `--bg-primary: #FDF6E3` (Papyrus — never pure white; use `#fefefe` only if a near-white is unavoidable)
- `--bg-secondary: #F3E8CD` (aged parchment panel tone)
- `--text-primary: #2B2118` (Dark Brown)
- `--text-secondary: #8B7355` (Sandstone)
- `--primary: #C17817` (Gold Ochre)
- `--secondary: #B55A2F` (Burnt Sienna)
- `--text-success: #4E6E3D` (deep oasis green, AA contrast on papyrus)
- `--text-error: #A93B2A` (deep terracotta)
- `--border-default: #8B7355`; `--border-success` / `--border-error` derived from the success/error tokens
- Supporting tones: Warm Tan `#D4A574`, Charcoal `#4A4A4A`
- **Contrast pairing (enforced in every theme):** papyrus/parchment backgrounds pair with Dark Brown text; dark stone backgrounds pair with Papyrus/Gold text.

**0.4 Color Tokens — Dark Mode "Tomb Night"**
- `--bg-primary: #1E1710` (deep basalt), `--bg-secondary: #2B2118` (Dark Brown)
- `--text-primary: #FDF6E3`, `--text-secondary: #D4A574`
- `--primary: #D9962F` (brightened Gold Ochre for AA contrast on dark), `--secondary: #C9714A` (lightened Burnt Sienna)
- Success/error tokens lightened to pass AA on dark backgrounds. All pairings from 0.3 remain enforced.

**0.5 Typography & Icons**
- **Google Fonts (mandatory):** Headings — `Cinzel` (600/700, monumental stone-carved feel), bound to `--font-heading`. Body — `EB Garamond`, bound to `--font-base`. Include via `<link>` in `<head>`.
- **Icons:** Google Material Symbols only (e.g., `history_edu`, `museum`, `translate`, `explore`, `auto_stories`, `visibility`, `savings`, `help`, `close`, `menu`, `dark_mode`, `light_mode`, `check`, `error`, `arrow_forward`). Bind via `<link>` in `<head>`.
- **Raw inline SVG icons and local icon files are forbidden.**
- **Exception clause (ornamentation only):** hieroglyphic ornamental border patterns may be implemented as data-URI SVG `border-image`/`background-image` values defined **inside `style.css` only** — never as inline `<svg>` markup in HTML. Every functional/semantic icon must remain a Google Material Symbols glyph.

**0.6 Ornament, Texture & Illustration System**
- **Papyrus texture overlay:** a low-opacity aged-paper grain implemented as a data-URI noise/pattern asset (e.g., SVG `feTurbulence` grain) or a CSS repeating pattern of flat dots/lines — **never via color gradients**. Applied to `body`/panels without affecting text contrast.
- **Ornamental borders:** flat, single-color geometric repeats (lotus, step/greek-key motifs) via the permitted data-URI technique or pseudo-element strips of Material Symbols glyphs. Borders animate subtly on scroll/hover (pattern opacity or offset shift) using CSS transitions.
- **Flat profile figures:** decorative frontalism figures composed from flat single-color CSS shapes or data-URI assets, uniform fill, no gradients, marked `aria-hidden="true"`, purely decorative.
- **Triptych layout:** Features and How It Works render as three equal compartments separated by ornamental dividers; collapse to a single column on mobile.
- **Carved shadows:** define `--shadow-sm`/`--shadow-md` as hard, flat offset shadows (solid color, no blur) to preserve the stone-carved aesthetic.

## 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 or ID selectors in `style.css`.
- **Minimal HTML Modifications:** HTML remains clean, semantic, and style-agnostic; retheming the site must require editing only the CSS file, never the markup.

**1.2 CSS Variables & Theme Tokens**
- Store every token in `:root` (light) and override under both `@media (prefers-color-scheme: dark)` and a `.dark` class: all colors from 0.3/0.4, plus `--radius-sm`, `--radius-md`, `--radius-lg` (favor sharp/carved corners, e.g., `0–2px`, but tokens must exist and be used), `--shadow-sm`, `--shadow-md`, `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`, `--z-dropdown`, `--z-modal`, `--z-toast`, `--font-base`, `--font-heading`.
- **Contrast Pairing:** every light background token pairs with a dark text token and vice versa — enforced in both themes.

**1.3 Mandatory Dark Mode Support**
- **Implementation:** dark tokens defined under both the media query and the `.dark` class selector.
- **Theme Switching:** background/text variables must swap seamlessly with zero HTML restructuring.
- **Persistence:** user choice persists via `localStorage`, falling back to `prefers-color-scheme` on first visit. A visible toggle button in the header (Material Symbols `dark_mode`/`light_mode`) carries correct `aria-pressed` and `aria-label` state.

**1.4 Flexbox Layout & Mobile-First Alignment**
- Build all layout structures with Flexbox (`display: flex` / Tailwind flex utilities).
- **Default Alignment Rule:** every flex container defaults to `align-items: center` (`items-center`) unless an exception is explicitly justified in a CSS comment.
- **Mobile-Friendly First:** triptychs, pricing rows, and nav convert rows to columns on small viewports; **no horizontal scrolling at any width**.

**1.5 Framework Default & Tailwind CSS Integration**
- Use Tailwind CSS (or clean custom CSS driven by Tailwind's `@layer`/`@apply`). All utility classes map back to CSS variables or generic reusable class names: `.btn`, `.card`, `.input-group`, `.ornament-frame`, `.triptych`, `.accordion`, `.toast`.

**1.6 Typography & Icons (Google Fonts Mandatory)**
- Google Fonts `<link>` tags for Cinzel and EB Garamond, bound to `--font-heading` and `--font-base`.
- Google Material Symbols for all icons; raw inline SVGs and local icon files are forbidden, subject only to the ornamentation exception in 0.5.

## 2. COMPONENT DESIGN SPECIFICATIONS

**2.1 Button Component**
Style all states via CSS classes only:
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum touch target 44×44px. Variants: `.btn--primary` (Gold Ochre fill, Dark Brown text), `.btn--secondary` (outlined Burnt Sienna), `.btn--danger` (distinct in both themes).
- **Hover:** brightness shift or carved-shadow shift with `cursor: pointer`.
- **Focus:** distinct focus ring built from CSS variables (`outline`/`box-shadow`) for keyboard navigation.
- **Active/Pressed:** `transform: scale(0.97)`.
- **Loading:** interactions disabled, double-clicks prevented, CSS spinner or animated Material Symbol rendered without distorting button dimensions (newsletter submit in Final CTA must demonstrate this).
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Success/Error:** temporary feedback states driven by `--text-success`/`--text-error`, never color alone (pair with icon/text).

**2.2 Card Component** (Features cards, Testimonials, Pricing tiers)
- **Default:** flexible Flexbox layout, `--bg-secondary` fill, ornamental border, flat carved shadow via `--shadow-sm`.
- **Hover:** `transform: translateY(-2px)` and/or carved-shadow shift.
- **Focus-within:** card border highlights in `--primary` when a child link/button receives focus.
- **Loading (Skeleton):** shimmer animation defined in CSS (flat opacity pulse — no gradient shimmer) to prevent layout jumps.
- **Empty State:** structured fallback with a Material Symbol and clear guidance text.
- **Pricing:** middle tier uses `.card--featured` with a gold ornamental frame and elevated visual weight; each tier lists a themed name (e.g., Apprentice / Scribe / Pharaoh), price, feature list with `check` icons, and a CTA button.

**2.3 Form & Input Requirements** (Final CTA newsletter signup)
- **States:** Empty, Focused (outline ring in `--primary`), Filled, Valid (success border + `check` icon), Invalid (error border, `--text-error` text, `error` icon, message in a dedicated `aria-live` container), Disabled, Read-only.
- **Structure:** flex container wrapping a `<label>`, the input field, and a dedicated error-feedback container.

**2.4 FAQ Accordion**
- Semantic `<details>`/`<summary>` or a fully ARIA-compliant custom accordion (`button`, `aria-expanded`, `aria-controls`); keyboard operable; open/close animated via CSS transitions; chevron icon rotates; answers never rely on hover to be reachable.

**2.5 Modal / Popup** (only if a "View details" action on pricing is included)
- **States:** Opening, Open, Loading, Success/Error, Closing — all animated via CSS transitions.
- **UX:** centered flex container (`align-items: center`), backdrop overlay, Material `close` icon button, keyboard focus trapping, close via `Esc` and overlay click, stacked at `--z-modal`.

**2.6 Header & Navigation**
- Sticky header with papyrus/stone background, text logo in `--font-heading`, anchor links to every section, mobile hamburger menu (Material `menu` icon, panel at `--z-dropdown`, keyboard accessible), and the theme toggle. Smooth scrolling with `scroll-margin-top` compensating for the sticky header.

**2.7 Toast Notification**
- Form success/error feedback rendered as a toast at `--z-toast` with an `aria-live="polite"` region, auto-dismiss, and icon + text (never color alone).

**2.8 Scroll Reveal**
- Subtle section-entry reveals (fade/rise + ornamental border draw-in) via an IntersectionObserver in `script.js` that adds a visibility class; all reveal styles are scoped under a class the script adds to `<html>`, so **content is fully visible without JavaScript**. Honor `prefers-reduced-motion`.

## 3. CORE UX & MICRO-INTERACTION RULES

- **Responsive by Default:** fluid sizing (`clamp()` for typography), standard breakpoints, zero horizontal overflow.
- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; every animation disabled/reduced under `prefers-reduced-motion`.
- **Accessibility (a11y):** WCAG AA contrast in both Papyrus Day and Tomb Night; never rely on color alone to communicate state; semantic HTML5 elements; correct ARIA roles/labels on all custom widgets (menu, accordion, toggle, toast); logical DOM/focus order; full keyboard operability with visible focus; `aria-live` regions for form errors, toasts, and loading states.
- **Mandatory Visual Feedback:** every click, hover, and submission triggers a visible state change.
- **Destructive Actions:** `.btn--danger` visually distinct in both themes.
- **Flat Aesthetic Integrity:** no gradients of any kind; all texture, depth, and ornament are pattern-, border-, or flat-shadow-based.

## 4. DELIVERABLE & OUTPUT FORMAT

- **File Structure:** separate `index.html`, `style.css`, and `script.js`. The only script reference is a single `<script src="script.js" defer></script>`; no inline `<script>` blocks. No external image files — all visuals are CSS, data-URI, or Material Symbols.
- **Naming Convention:** one consistent convention across the entire deliverable — BEM (`.card__title`, `.card--featured`, `.btn--primary`, `.accordion__item`). Never mix conventions.
- **Copy:** write real, thematic English copy for every section (scholarly, archaeological, mysterious-but-clear tone); realistic fictional testimonials (e.g., an Egyptologist, a museum curator, a graduate researcher). Lorem-ipsum-only submissions are prohibited; placeholders are allowed only where content was genuinely left unspecified.
- **Output:** complete, runnable code on the first attempt — no TODOs, no truncated sections, no "rest of the code follows the same pattern."
