The user wants me to create a Matrix digital rain effect. This is a classic visual effect from the Matrix movies. I need to create a single HTML file with: 1. Full-screen black canvas 2. Columns of falling green katakana characters 3. Trailing fade effect (characters fade out as they fall) 4. Brighter leading character at the front of each column Let me create this as a self-contained HTML file with CSS and JavaScript. I'll use the HTML5 Canvas API for this. Key elements: - Full-screen black background - Katakana characters (I'll use a set of Japanese katakana characters) - Green color with varying brightness - Each column has multiple characters falling - The top character is brightest, trailing characters fade - Random starting positions and speeds for each column Let me write this:

I've created the Matrix digital rain effect. Let me verify the file was created correctly and review the code to make sure it meets all the requirements: 1. ✓ Full-screen black canvas 2. ✓ Columns of falling green katakana glyphs 3. ✓ Trailing fade effect (using semi-transparent black overlay) 4. ✓ Brighter leading character (random chance for extra bright green with glow) The code uses: - HTML5 Canvas for rendering - Katakana characters + some Latin/numbers - Semi-transparent black fillRect to create the trail/fade effect - Random bright green for the leading character with a shadowBlur effect for extra glow This should work well. Let me verify the file exists.

The file has been created successfully. Let me verify the content is correct by reading a portion of it.
Created `index.html` with the Matrix digital rain effect featuring: - **Full-screen black canvas** - Covers the entire viewport with no margins - **Katakana glyphs** - Japanese katakana characters plus Latin letters/numbers for variety - **Falling columns** - Characters cascade down in randomized columns - **Trailing fade effect** - Semi-transparent black overlay creates the classic fading trail - **Brighter leading character** - Random characters at the "head" of each drop glow bright green with a blur effect The effect uses the HTML5 Canvas API with `requestAnimationFrame` for smooth 60fps animation. Open `index.html` in any browser to view the Matrix rain.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
