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 in index.html. Let me create a self-contained HTML file with CSS in a <style> tag and JS in a <script> tag, no external resources.

The effect should have:
- Full-screen black canvas
- Columns of falling green katakana glyphs
- Trailing fade
- Brighter leading character

Let me write this carefully.

I'll create the Matrix digital rain effect as a single self-contained HTML file.

Let me verify the file exists and is valid.

Let me verify the file is in place and valid:

EVALUATION

3/5 working

Matrix rain effect with falling katakana glyphs animates but seems sparse, only near top of screen, not full-screen coverage.

Vision grade · anthropic/claude-sonnet-5

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.
