## 1. STRICT RULES & ARCHITECTURE

### 1.1 CSS-First Architecture & Zero Inline CSS
- **No Inline CSS:** The `style="..."` attribute is forbidden in all HTML.
- **Class/ID Selectors Only:** All styling lives in `style.css` via class/ID selectors.
- **Minimal HTML Modifications:** HTML stays semantic and clean; visual changes happen only in CSS.

### 1.2 CSS Variables & Theme Tokens
Define all tokens in `:root` (and theme overrides):
- **Colors:** `--primary: #ffffff`, `--bg-primary: #000000`, `--bg-secondary: rgba(255,255,255,0.05)`, `--text-primary: #ffffff`, `--text-secondary: rgba(255,255,255,0.6)`, `--text-label: rgba(255,255,255,0.4)`, `--border-default: rgba(255,255,255,0.2)`, `--border-hover: rgba(255,255,255,0.1)`, `--text-success`, `--text-error`, `--border-success`, `--border-error`.
- **Contrast Pairing:** Dark backgrounds always pair with light text tokens; light backgrounds pair with dark text tokens.
- **Radius/Shadow:** `--radius-sm`, `--radius-md`, `--radius-lg`, `--shadow-sm`, `--shadow-md`.
- **Spacing/Motion:** `--spacing-gap`, `--transition-fast`, `--transition-normal`, `--ease-standard`.
- **Stacking:** `--z-dropdown`, `--z-modal`, `--z-toast` (video overlays sit below content; modals/toasts above).

### 1.3 Dark Mode Support
- **Mandatory:** Define dark mode tokens under `@media (prefers-color-scheme: dark)` and a `.dark` class selector.
- **Exception Clause:** This theme is cinematic dark-first (`#000000` base). The "dark mode" tokens ARE the default theme; still define a `.light`/light-scheme token set (near-black text on `#fefefe` background) so the toggle works both ways, preserving the glass-morphism and vignette effects.
- **Persistence:** Theme choice persists via `localStorage`, falling back to `prefers-color-scheme`. Include a visible toggle with correct `aria-pressed`/`aria-label` state.

### 1.4 Flexbox Layout & Mobile-First Alignment
- **Default Alignment:** Every flex container defaults to `align-items: center` unless explicitly justified.
- **Mobile-First:** All rows convert to columns on small viewports; no horizontal scrolling ever.

### 1.5 Framework Default
- Use Tailwind CSS (CDN or build) with all utilities mapped back to CSS variables or reusable classes (`.btn`, `.card`, `.glass-card`, `.pill-tag`, `.spec-row`). One consistent naming convention throughout — never mix conventions.

### 1.6 Typography & Icons (Google Fonts Mandatory)
- **Fonts (Google Fonts):** Orbitron (display headings, uppercase, tight tracking), Space Grotesk (body), JetBrains Mono (technical/mono elements). Bind via `--font-display`, `--font-base`, `--font-mono`.
- **Icons:** Google Material Symbols only. **No raw inline SVGs, no local icon files.**
- **Selection:** `::selection { background: #ffffff; color: #000000; }` (inverted in light theme).

## 2. THEME SPECIFICATION — "Architectural Portfolio Cinematic"

**Aesthetic:** Minimalist, cinematic, dark (#000000 bg / #FFFFFF text), sophisticated typographic hierarchy, glass morphism, pill tags, technical spec lists, 2025–2026 creative-portfolio era.

### 2.1 Visual Effects
- **Hero Video:** Full-screen looping background video of futuristic architecture (use a stock video URL, e.g. from Coverr/Pexels CDN). Attributes: `muted`, `playsinline`, `loop`, `preload="auto"`. Provide a `poster` fallback image.
- **Vignette (desktop):** Radial overlay — `background: radial-gradient(ellipse at center, transparent 30%, rgba(0,0,0,0.7) 100%)`.
- **Mobile (max-width: 768px):** Video occupies top half only (`height: 50vh`) with a smooth bottom-fade gradient (`linear-gradient(to bottom, transparent, #000000)`) blending into content below.
- **Glass Cards:** `background: rgba(255,255,255,0.05); backdrop-filter: blur(24px); -webkit-backdrop-filter: blur(24px);` with `rgba(255,255,255,0.2)` borders.
- **Pill Tags:** `border: 1px solid rgba(255,255,255,0.2); border-radius: 9999px;` mono font, small size.
- **Page Transitions:** Opacity + Y-offset animations (`transition: opacity 0.6s ease, transform 0.6s ease`) between the two "pages" (Hero page and Project page), driven by JS class toggling.
- **Counter:** Top-right `1/01` mono counter with a thin progress line; `2/02` on the project page.

### 2.2 Two-Page Structure (within the single landing page)
**Page 1 — Hero:**
- Top nav: right-aligned `1/01` counter with progress line + "Next Project" button (mono font).
- Main title: `VIKTOR-O // MODERN ARCHITECT` — Orbitron, uppercase, tight tracking.
- Description: Space Grotesk light, max-width 450px.
- Right column: technical specs list (Stack, Logic, Uptime, Scale) — labels in `rgba(255,255,255,0.4)`, values in white, rows separated by thin `rgba(255,255,255,0.2)` borders.
- Bottom: glass-morphism card with `VK-01: React Engine` title + "View Project" button.
- Bottom right: pill tags row: `TS/JS`, `V1`, `Full-Stack`, `Cloud-Ready`.

**Page 2 — Project:**
- "Back Home" button with arrow Material Icon.
- Massive display title `PROJECT ENGINE` — Orbitron, `line-height: 0.85`, uppercase.
- Right-aligned description about the flagship React engine + "Read More" link.
- Two structured info blocks: `01 CORE ARCHITECTURE` and `02 PERFORMANCE METRICS` with uppercase mono subtext.
- Navigation arrows in circular `rgba(255,255,255,0.2)` borders + meta-info block.

### 2.3 Landing Page Sections (in order)
1. **Hero** (Page 1 as specified above)
2. **Features** — 3 glass cards, each with a Google Material Icon, Orbitron heading, Space Grotesk description
3. **How It Works** — 3 numbered steps (`01`, `02`, `03` in JetBrains Mono), thin border separators
4. **Testimonials** — glass cards with quote, name, role; mono attribution
5. **Pricing** — 3 tiers; middle tier highlighted (elevated glass card, "Most Popular" pill tag); each with feature list and CTA button
6. **FAQ** — accordion using semantic `<details>/<summary>` or ARIA-correct custom accordion; smooth CSS height/opacity transitions; never color-only state indicators
7. **Final CTA** — full-width glass panel, large Orbitron headline, primary button
8. **Footer** — secondary links, social icons (Material Symbols), mono copyright line

## 3. COMPONENT STATE SPECIFICATIONS

### 3.1 Buttons
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px touch target.
- **Hover:** Brightness/shadow shift, `cursor: pointer`.
- **Focus:** Distinct focus ring via `outline`/`box-shadow` using CSS variables.
- **Active:** `transform: scale(0.97)`.
- **Loading:** Disables interaction, prevents double-clicks, CSS spinner that doesn't distort dimensions.
- **Disabled:** `opacity: 0.5`, greyscale, `cursor: not-allowed`.
- **Danger:** `.btn-danger` visually distinct in both themes.

### 3.2 Cards
- **Default:** Flexbox layout, `--bg-secondary` fill, subtle borders.
- **Hover:** Shadow elevation shift or `transform: translateY(-2px)`.
- **Focus-within:** Border highlight when child link/button is focused.
- **Skeleton:** Shimmer animation for loading states (no layout jumps).
- **Empty State:** Google Icon + guidance text fallback.

### 3.3 Forms & Inputs (e.g., Final CTA email capture, if included)
- **States:** Empty, focused (outline ring), filled, valid (success border/icon), invalid (error border, red text, error icon), disabled, read-only.
- **Structure:** Flex container wrapping label, input, and dedicated error feedback container with `aria-live`.

### 3.4 Modals (e.g., "Read More" project details)
- **States:** Opening, open, loading, success/error, closing — all CSS-transitioned.
- **UX:** Centered flex overlay, Google Icon close button, keyboard focus trapping, close via `Esc` and overlay click.

## 4. CORE UX & MICRO-INTERACTION RULES
- **Responsive by Default:** Fluid sizing, no horizontal overflow; hero video → `50vh` top-half on mobile with gradient fade.
- **Smooth Animations:** `transition: var(--transition-normal)` on all state changes; respect `prefers-reduced-motion` (disable video parallax/transitions).
- **Accessibility:** Sufficient contrast in both themes; never color-only state signals; semantic HTML5; correct ARIA roles/labels on the accordion, page tabs, and toggle; logical focus order; full keyboard operability; `aria-live` regions for dynamic feedback (form errors, toasts, loading).
- **Mandatory Visual Feedback:** Every click, hover, and submission triggers a visible state change.
- **All user-facing copy in English.**

---

## 5. DELIVERABLE & OUTPUT FORMAT
- **Files:** Separate `index.html`, `style.css`, `script.js`. No inline `<script>` blocks beyond one deferred entry-point reference. No inline CSS.
- **Naming:** One consistent convention (BEM or fixed utility set) across the entire deliverable.
- **Content:** Real, theme-appropriate copy for all sections — no lorem-ipsum placeholders.
- **Output the complete, runnable code for all three files immediately.**
