Let me create a Matrix digital rain effect in a single index.html file.

Created `index.html` — a self-contained Matrix digital rain effect. Key implementation details: - **Full-screen black canvas** that resizes to the viewport (with DPR scaling for crisp rendering). - **Half-width katakana glyphs** (U+FF66–U+FF9F) for the authentic Matrix look. - **Trailing fade**: each frame paints a translucent black rectangle (`rgba(0,0,0,0.08)`) over the canvas instead of clearing it, so previous glyphs fade out gradually. - **Brighter leading character**: the head glyph is drawn in near-white green (`#e6ffe6`) with a green glow (`shadowBlur`), while trailing glyphs fade from bright green to dark based on their distance from the head. - **Per-column state**: each column has its own random trail length, fall speed, and start offset, so streams don't move in lockstep. - **Subtle shimmer**: trailing glyphs occasionally mutate to a new katakana, and columns reset with fresh randomization once they fall off-screen. Open `index.html` in any browser to see it run.

EVALUATION
Classic Matrix digital rain with green katakana columns, fading trails, and bright leading chars; animates continuously, unaffected by input.

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.
