**Role:** You are a Frontend Specialist in Creative Coding, focusing on "Glitch Art" and aggressive Cyberpunk aesthetics using pure CSS.
**Task:** Develop the "NEON_NEXUS" landing page.
**[CONFIGURATION]**
- **[STYLE_NAME]:** Cyberpunk / Bio-Hacking
- **[INDUSTRY]:** Bio-Augmentation
- **[PROJECT_NAME]:** NEON_NEXUS
- **[TECH_STACK]:** HTML5 + Vanilla CSS3 (Embedded).
- **[PAGE_STRUCTURE]:** Navbar, Glitch Hero, Features, Metrics, Timeline, Pricing, Footer.
**Technical Requirements:**
1. **Global Variables (`:root`):**
- **Neon Palette:** `--theme-cyan: #00f2ff;`, `--theme-magenta: #ff00ff;`, `--theme-acid: #ccff00;`.
- **Dark Mode:** `--bg-dark: #0f2223;`, `--surface-dark: #162e30;`.
- **Fonts:** `--font-display: 'Space Grotesk', sans-serif;`.
2. **Key Visual Effects (The "Cyber" Look):**
- **CRT Scanlines:** Implement a fixed, full-screen overlay using `linear-gradient` to create horizontal scanlines that dim the screen slightly.
- **Angled Corners (Chamfered):** DO NOT use `border-radius`. Use `clip-path: polygon(...)` to cut 45-degree angles off the corners of buttons and cards.
- **Glitch Text:** Create a `@keyframes` animation using `clip: rect(...)` and `transform: translate(...)` to make the main H1 title jitter and split into RGB layers.
- **Neon Bloom:** Use `box-shadow` liberally on hover states to create a glowing light effect (e.g., `box-shadow: 0 0 20px var(--theme-cyan)`).
3. **Layout & Components:**
- **Hero:** Full viewport height. Background image must have a heavy dark overlay to ensure neon text pops.
- **Timeline:** A vertical line connecting steps. Use CSS pseudo-elements (`::before`, `::after`) to draw the circuit lines and nodes.
- **Pricing Chips:** Style the pricing cards to look like physical hardware (RAM sticks or Datashards) with a "connector" detail at the bottom.
4. **Interactivity:**
- Hover effects should be instant and sharp (no slow fades), mimicking digital switching.
