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 in a single HTML file. This is a classic visual effect that features:
1. A black canvas background
2. Columns of falling green characters (katakana)
3. A trailing fade effect
4. Brighter leading character at the front of each trail

I'll create this using HTML5 Canvas and JavaScript. The key elements:
- Full-screen canvas
- Katakana characters array
- Multiple columns with different drop positions
- Trail effect by drawing semi-transparent black rectangles over previous frames
- Different brightness for leading character vs trailing characters

Let me write this self-contained HTML file.

→ write index.html (3134 bytes)

The file has been created successfully. The Matrix digital rain effect is now ready. Let me summarize what the file contains for the user.

Created `index.html` with the Matrix digital rain effect: - **Full-screen black canvas** that adapts to window size - **Falling green katakana glyphs** (plus Latin letters and numbers) in columns - **Trailing fade effect** using semi-transparent black overlays - **Brighter leading character** - occasionally a white character appears at the front of each trail - Runs at ~30 FPS for that retro CRT feel Open `index.html` in a browser to see the effect.
