### 1. ARCHITECTURE RULES

**1.1 CSS-First Architecture & Zero Inline CSS**
* All styling lives in `style.css`. The `style="..."` attribute is forbidden in HTML.
* Target all design via class/ID selectors only. HTML stays semantic and clean.
* Changing the theme must require editing only `style.css`, never the markup.

**1.2 CSS Variables & Theme Tokens**
Define all tokens in `:root` (light) and a `.dark` / `@media (prefers-color-scheme: dark)` block:
* Colors: `--primary: #6A0DAD` (Royal Purple), `--secondary: #014D4E` (Deep Teal), `--bg-primary`, `--bg-secondary`, `--text-primary`, `--text-secondary`, `--text-success`, `--text-error`, `--border-default: #E6A817` (Sahara Gold), `--border-error`, `--border-success`.
* Accent tokens: `--accent-gold: #E6A817`, `--accent-amber: #FFBF00`, `--accent-terracotta: #C1440E`, `--accent-violet: #8F00FF`, `--accent-sand: #C2B280`, `--obsidian: #0D0D0D`.
* **Light mode:** Obsidian-black text on warm sand/amber-tinted backgrounds (e.g., `#C2B280`-tinted warm tones); use `#fefefe` where near-white is needed — never `#ffffff`. **Dark mode:** `--bg-primary: #0D0D0D` (Obsidian), `--bg-secondary` a deep purple-teal tone, `--text-primary: #FFBF00` (Warm Amber), `--text-secondary: #C2B280`. Enforce light/dark contrast pairing in BOTH themes.
* Radius/shadows: `--radius-sm/md/lg`, `--shadow-sm/md`, plus `--glow: 0 0 20px rgba(106,13,173,0.5)` and `--text-glow: 0 0 8px rgba(230,168,23,0.4)`.
* Spacing/transitions: `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`, `--z-dropdown`, `--z-modal`, `--z-toast`.

**1.3 Mandatory Dark Mode**
* Dark mode is the hero aesthetic (obsidian + gold glow) but BOTH modes must be fully defined.
* Implement via `.dark` class + `@media (prefers-color-scheme: dark)` fallback; persist choice in `localStorage`; visible toggle button with `aria-pressed` and `aria-label="Toggle dark mode"`.

**1.4 Flexbox Layout & Mobile-First**
* Every flex container defaults to `align-items: center` unless justified otherwise. Rows collapse to columns on small viewports. No horizontal scrolling at any width.

**1.5 Framework**
* Use Tailwind CSS utilities (or custom CSS via `@layer`/`@apply`) mapped to the CSS variables above. Reusable classes: `.btn`, `.btn-primary`, `.btn-gold`, `.card`, `.section`, `.container`.

**1.6 Typography & Icons (Google Fonts Only)**
* Text: **Josefin Sans** via Google Fonts `<link>`, bound to `--font-base`. Use a display weight (700) for headings, 400 for body.
* Icons: **Google Material Symbols** only. No inline SVGs, no local icon files.

### 2. AFROFUTURIST VISUAL DIRECTION

* **Cosmic star field:** Hero background uses layered CSS radial gradients (`radial-gradient` dots at varying sizes/opacities) over `--bg-primary`, animated with a slow drift `@keyframes`. Respect `prefers-reduced-motion`.
* **Kente-inspired grid:** Section backgrounds may use repeating CSS gradients (striped/banded patterns in gold/purple/teal) with `background-blend-mode: soft-light` — pure CSS, no image files.
* **Radial symmetry & geometry:** Decorative concentric circles, triangles, and diamond motifs built from CSS borders/`clip-path` on pseudo-elements.
* **Rhythm animation:** `@keyframes rhythm-pulse` (scale/opacity pulse, `1.5s ease-in-out infinite`) applied to accent elements (glowing orbs, CTA halo rings, icon badges).
* **Metallic gold accents:** Gold borders (`border: 2px solid #E6A817`), `--glow` box-shadows, `--text-glow` text-shadows on hero headline and key CTAs.
* **Holographic masks:** Feature/testimonial cards may carry a subtle holographic sheen via a gradient overlay pseudo-element with slow hue-rotate animation.
* All decorative effects must be defined in CSS classes — never inline.

### 3. REQUIRED SECTIONS (in order)

1. **Header/Nav:** Logo (Material Symbol "auto_awesome" + wordmark), nav links, dark-mode toggle, CTA button.
2. **Hero:** Full-viewport cosmic star field, glowing headline with `--text-glow`, subheadline, two CTAs (`.btn-gold` primary, `.btn` outline secondary), pulsing radial ornament.
3. **Features (3 cards):** `.card` grid — each with a Material Symbol icon badge (rhythm-pulse animation on hover), title, description. Cards lift `translateY(-2px)` + shadow shift on hover; `:focus-within` gold border highlight.
4. **How It Works (3 steps):** Numbered vertical/horizontal flex steps with connecting gold line, diamond markers, icons.
5. **Testimonials:** 3 quote cards with avatar placeholder (initial letter in a gold-ringed circle), quote, name/role.
6. **Pricing (3 tiers):** Middle tier highlighted (gold border, `--glow`, "Most Popular" badge). Each tier: price, feature list (Material Symbol check icons), CTA button with full button states (hover, focus ring, active `scale(0.97)`, disabled `opacity: 0.5; cursor: not-allowed`).
7. **FAQ:** Native `<details>`/`<summary>` accordion styled with gold focus rings and animated open indicator (Material Symbol "expand_more" rotating).
8. **Final CTA:** Full-width obsidian/purple band with star-field texture, glowing headline, `.btn-gold` CTA.
9. **Footer:** Brand, secondary link columns, social icon links (Material Symbols), copyright, back-to-top link.

All user-facing copy in **English**, themed around ancestral-tech/cosmic identity (e.g., product name like "Ancestra" or similar Afrofuturist concept). Write real, meaningful copy — no lorem ipsum.

### 4. UX, A11Y & INTERACTION RULES

* Smooth transitions (`transition: var(--transition-normal)`) on all state changes; respect `prefers-reduced-motion` (disable star drift, rhythm-pulse, sheen animations).
* Accessibility: WCAG-AA contrast in both themes; semantic HTML5 (`header`, `main`, `section`, `footer`, `nav`); logical focus order; visible focus rings using `--accent-gold`; ARIA labels on toggle and icon-only links; `aria-live` region for any dynamic feedback (e.g., FAQ/theme announcements).
* Every interactive element has visible hover, focus, and active feedback.
* Buttons: min 44×44px touch targets, flex centered layout with `gap: 0.5rem`.
* Responsive: mobile-first; hero, cards, pricing, and steps stack vertically under 768px; no horizontal overflow.

### 5. DELIVERABLES

* Exactly three files: `index.html`, `style.css`, `script.js`. No inline `<script>` beyond one deferred entry-point `<script src="script.js" defer>`. No inline styles.
* `script.js` contains only: theme toggle + `localStorage` persistence, and FAQ accordion enhancement if needed. No form validation logic (no forms requested).
* One consistent naming convention (BEM or fixed utility set) across the entire deliverable.
* All decorative patterns via CSS gradients — no external image assets except Google Fonts/Icons.
* Output the complete, runnable code for all three files immediately.
