Create the Matrix digital rain effect on a full-screen black canvas: columns of falling green katakana glyphs with a trailing fade and a brighter leading character.

The user wants me to create a Matrix digital rain effect as a single-page web app. This is a classic visual effect featuring:
- Full-screen black canvas
- Green katakana characters falling in columns
- Trailing fade effect (characters fade as they fall)
- Brighter leading character at the front of each column

I'll create a self-contained HTML file with embedded CSS and JavaScript. The effect will use:
- A canvas element for rendering
- Katakana characters (Unicode range)
- Multiple columns with different speeds
- Fade effect using semi-transparent black overlay
- Bright white/green leading character

Let me write this all into index.html.

I've created the Matrix digital rain effect in a single self-contained HTML file. The file includes:

1. CSS in a `<style>` tag - sets up full-screen black background with no margins
2. JavaScript in a `<script>` tag - implements the Matrix rain effect with:
   - Full-screen canvas
   - Katakana characters (Japanese) mixed with Latin letters and numbers
   - Multiple columns of falling characters
   - Semi-transparent black overlay for trail fade effect
   - Random brightness with bright white leading characters
   - Random speeds for each column
   - Responsive to window resize

The effect should look authentic with green characters falling down with fading trails and brighter leading characters.

Created `index.html` with the Matrix digital rain effect featuring: - **Full-screen black canvas** with no scrollbars - **Green katakana glyphs** (Japanese characters) mixed with Latin letters and numbers - **Trailing fade effect** using semi-transparent black overlay - **Brighter leading characters** - white/bright green at the front of each column - **Random column speeds** for natural variation - **Responsive** - adjusts to window resize Open the file in a browser to see the effect.
