## 1. THEME DEFINITION & DESIGN DIRECTION

**1.1 Mood & Voice**
- Style: **Glitch UI Dystopian Terminal** — Urgent, Computational, Retro-Futuristic. Era: Dystopian Future. The page must feel like a corrupted terminal under red alert: urgent, chaotic, monitored.
- Write all copy in a clipped system-log voice (e.g., "SIGNAL ACQUIRED", "INITIALIZE UPLINK", "CONNECTION MONITORED"). No lorem ipsum — author real, coherent copy for a fictional off-grid counter-surveillance product (suggested name: "NULLSEC"; refine naming as needed).

**1.2 Color Palette → CSS Tokens (define in `:root`)**
- `--bg-primary: #050000` (void black), `--bg-secondary: #330000` (dark red panels), `--primary: #FF0000` (alert red), `--secondary: #E0E0E0` (static white), `--text-primary: #FF5050`, `--text-secondary: #E0E0E0`, `--glitch-cyan: #00FFFF`.
- Derived: `--text-success: #00FFFF`, `--text-error: #FF0000`, `--border-default: rgba(255,0,0,0.35)`, `--border-error: #FF0000`, `--border-success: #00FFFF`.
- **Contrast pairing (mandatory):** `#050000`/`#330000` backgrounds pair only with `#FF5050`, `#E0E0E0`, or `#00FFFF` text; `#FF0000` fills pair only with `#050000` text. Body copy uses `--text-primary` or `--text-secondary` (≥ 4.5:1); reserve `#FF0000` for display text, borders, fills, and non-text accents.

**1.3 Signature Visual Effects (all CSS-only, decorative layers `aria-hidden` + `pointer-events: none`)**
- **Glitch text:** headline elements carry a `data-text` attribute mirroring their content; `::before`/`::after` copies animate via `clip-path` slices and `text-shadow: 2px 0 #FF0000, -2px 0 #00FFFF`. The real text node stays static and readable for screen readers.
- **CRT scanlines:** full-viewport fixed overlay (`repeating-linear-gradient`), opacity ≤ 0.12, `pointer-events: none`, z-index `--z-scanlines`.
- **Interference lines:** thin horizontal red/cyan bars drifting across sections.
- **HUD frames:** corner brackets on cards/sections via pseudo-elements; monospace status readouts ("SYS.STATUS: ONLINE").
- **Screen burn-in:** one fixed ghost layer at opacity ≤ 0.06.
- **Flicker:** brief one-shot flickers on hover/activation only. Never exceed 3 flashes per second anywhere on the page.

**1.4 Motion Language**
- `@keyframes glitch` with `animation: glitch 1s linear infinite` applies to decorative pseudo-layers only; interactive feedback uses `var(--transition-fast)`. All motion is disabled under `prefers-reduced-motion` (see 4.2).

## 2. STRICT RULES & ARCHITECTURE

**2.1 CSS-First Architecture & Zero Inline CSS**
- All styling lives in `style.css`. **No `style="..."` attributes in HTML.** Class/ID selectors only. HTML remains semantic and styling-agnostic — reskinning requires CSS edits only.

**2.2 CSS Variables & Theme Tokens**
- Store every token in `:root`: all colors from 1.2, plus `--radius-sm: 0`, `--radius-md: 2px`, `--radius-lg: 4px` (sharp terminal edges), `--shadow-sm: 0 0 8px rgba(255,0,0,0.2)`, `--shadow-md: 0 0 16px rgba(255,0,0,0.35)`, `--spacing-gap`, `--transition-fast: 120ms`, `--transition-normal: 250ms`, `--ease-standard`, and stacking tokens `--z-scanlines: 90`, `--z-dropdown: 100`, `--z-modal: 200`, `--z-toast: 300`. Component classes must always reference `var(--...)` — never hardcode hex values.

**2.3 Mandatory Dark Mode Support**
- Dark mode is the default and only mode: all `:root` tokens are dark values, and all background/text pairings follow the dark-mode contrast rules. **Exception (per theme spec):** this is a dark-only theme — omit light-mode tokens, the theme toggle, and localStorage persistence; the page renders dark regardless of `prefers-color-scheme`.

**2.4 Flexbox Layout & Mobile-First Alignment**
- Build all layout structures with Flexbox (`display: flex` / Tailwind flex utilities). Every flex container defaults to `align-items: center` unless explicitly excepted. Mobile-first: rows collapse to columns at breakpoints; zero horizontal scrolling; fluid `clamp()` typography.

**2.5 Framework Default & Tailwind CSS Integration**
- Use Tailwind CSS (CDN) for layout, spacing, and responsive utilities; all theme styling is custom CSS in `style.css` using BEM class names driven by the `:root` variables.

**2.6 Typography & Icons (Google Fonts Mandatory)**
- Load via Google Fonts `<link>` in `<head>`: **Share Tech** (`--font-base`, per spec) and **Share Tech Mono** (`--font-mono`, for boot logs, readouts, labels, and terminal elements). Uppercase with letter-spacing on labels.
- Icons: **Google Material Symbols, Outlined variant only** (matches wireframe iconography). **Inline SVGs and local icon files are forbidden.** Decorative icons get `aria-hidden="true"`; functional icons carry accessible names.

## 3. COMPONENT DESIGN SPECIFICATIONS

**3.1 Button (`.btn`, `.btn--primary`, `.btn--ghost`, `.btn--danger`)**
- **Default:** `display: flex; align-items: center; justify-content: center; gap: 0.5rem;` minimum 44×44px, uppercase mono label. Primary: `#FF0000` fill + `#050000` text. Ghost: transparent fill, `--text-primary` text, `--border-default` border.
- **Hover:** brightness/shadow shift + one-shot glitch flicker; `cursor: pointer`.
- **Focus:** visible `--glitch-cyan` ring (`outline: 2px solid`, 2px offset) — never suppress.
- **Active:** `transform: scale(0.97)`.
- **Loading:** `aria-busy="true"`, interactions blocked, double-clicks prevented, CSS spinner (red/cyan) or pulsing Material icon; button dimensions unchanged.
- **Disabled:** `opacity: 0.5`, grayscale, `cursor: not-allowed`.
- **Success/Error:** temporary border + label shift via `--text-success`/`--text-error`, always paired with an icon or text — never color alone.
- **`.btn--danger`:** hazard-stripe accent (`repeating-linear-gradient(45deg, #FF0000, #330000)`) + `warning` icon — visually distinct from primary in this dark-only theme.

**3.2 Card (`.card`)**
- **Default:** flexible flexbox layout, `--bg-secondary` panel, 1px `--border-default`, HUD corner brackets.
- **Hover:** `transform: translateY(-2px)` + shadow/border shift + brief flicker.
- **Focus-within:** border highlights when a child link/button receives focus.
- **Loading (skeleton):** shimmer keyframes (static under reduced motion) with no layout jump.
- **Empty state:** centered Material icon + guidance text fallback.

**3.3 Form & Input (`.input-group`)**
- **Structure:** flex container wrapping `<label>`, `<input>`, and a dedicated error `<p>` container.
- **States:** empty, focused (cyan ring), filled, valid (cyan border + check icon), invalid (red border, `--text-error` message, error icon, `aria-live` announcement), disabled, read-only.
- Inputs: `#050000` fill, `#E0E0E0` text, red caret, mono font.

**3.4 Modal / Popup (`.modal`)**
- Apply to any dialog used (e.g., an optional "SYSTEM ALERT" confirmation for danger actions).
- **States:** opening, open, loading, success/error, closing — all animated via CSS transitions (backdrop fade + panel glitch-in).
- **UX:** centered flex container (`align-items: center`), dark backdrop with scanline texture, Material icon close button, keyboard focus trapping, close via `Esc` and overlay click, correct `role="dialog"`/`aria-modal`/labeling.

## 4. CORE UX & MICRO-INTERACTION RULES

**4.1 Responsive by Default:** fluid sizing, breakpoint collapse, no horizontal overflow.
**4.2 Motion Safety (critical for this theme):** under `prefers-reduced-motion: reduce`, disable all glitch, scanline, flicker, shimmer, and typing animations while keeping static chromatic text-shadows; no strobe effects anywhere.
**4.3 Accessibility (a11y):** semantic HTML5 landmarks, skip link, visible focus everywhere, full keyboard operability, ARIA on custom widgets (accordion, mobile menu), `aria-live` regions for dynamic feedback (form errors, toasts, loading states), never color-alone state communication, ≥ 4.5:1 body-text contrast.
**4.4 Mandatory Visual Feedback:** every click, hover, and submission triggers a visible state change.
**4.5 Smooth Animations:** `transition: var(--transition-normal)` on all state changes.

## 5. LANDING PAGE SECTION SPECIFICATION

**5.0 Global Header (HUD status bar):** fixed slim bar — brand mark, anchor links to all sections, one `.btn--primary` CTA, live status readout; accessible hamburger menu below 768px (`aria-expanded` panel).

**5.1 Hero:** full-viewport HUD frame; boot-log line sequence; glitch headline (per 1.3) + subheadline; two CTAs (`.btn--primary` "INITIALIZE UPLINK", `.btn--ghost`); animated terminal readout (CSS `steps()` typing; static under reduced motion); alert badges.

**5.2 Features — 3 cards:** flex-wrap row → column on mobile; each card: outlined Material Symbol icon, title, description; hover per 3.2.

**5.3 How It Works — 3 steps:** numbered "STEP_01 / STEP_02 / STEP_03" terminal steps connected by an interference line (horizontal on desktop → vertical on mobile), icon + text each.

**5.4 Testimonials — 3 quotes:** styled as intercepted transmissions — header row ("TRANSMISSION_042 // SECTOR-7"), quote in `--text-secondary`, author + affiliation; card styling per 3.2.

**5.5 Pricing — 3 tiers:** flex row → column; middle tier highlighted (alert border, glow, "PRIORITY ACCESS" badge); each tier: name, price, feature list with check/error Material icons, `.btn` CTA (one tier may use `.btn--danger`).

**5.6 FAQ — accessible accordion:** 5–6 Q&A pairs; `<details>/<summary>` or button + `aria-expanded` + region pattern; animated open/close, rotating chevron icon, hover + focus states, fully keyboard operable.

**5.7 Final CTA:** warning banner ("FINAL TRANSMISSION" style) with an email-capture form per 3.3 — validate input, show inline errors in an `aria-live` region, loading state on submit, success state on completion.

**5.8 Footer:** flex columns — brand + tagline, secondary link groups (Product, Company, Legal: About, Docs, Terms, Privacy, Contact), Material Symbol social icons with labels, bottom status line ("CONNECTION MONITORED — © 2087 NULLSEC"). All links get hover/focus glitch-underline feedback.

## 6. DELIVERABLE & OUTPUT FORMAT

- **File Structure:** separate `index.html`, `style.css`, and `script.js`. Only one `<script src="script.js" defer>` reference; no inline scripts; no inline styles.
- **Head:** Google Fonts links (Share Tech, Share Tech Mono) + Material Symbols link.
- **Naming Convention:** BEM only (`.card__title`, `.btn--primary`) — one consistent convention across the entire deliverable, never mixed.
- **Copy:** all user-facing copy in English, real themed content — no lorem-ipsum-only submissions.
- **No Unrequested Placeholders:** do not add features, sections, or placeholder content beyond this specification. Generate the final code immediately.
