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 a Matrix digital rain effect, implemented as a single self-contained `index.html` file. No external resources (CSS/JS in style/script tags). I need to create the file in /workspace/index.html.

Features: full-screen black canvas, columns of falling green katakana glyphs, trailing fade, brighter leading character. Implementation with HTML5 canvas. Use requestAnimationFrame. Handle resize. Katakana characters range. Need trailing fade: draw semi-transparent black overlay each frame. Leading character brighter green/white. Random drops and speeds. Keep it minimal and self-contained.

  Wrote file. Need answer with path.

Created `/workspace/index.html` — a single-file, self-contained Matrix rain effect with full-screen black canvas, green katakana columns, trailing fade via per-frame alpha overlay, and a brighter leading character rendered with a glow.

EVALUATION

3/5 working

Matrix rain effect animates continuously with green katakana glyphs, but background is oddly solid green rather than black.

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.
