The user wants a Matrix digital rain effect. Let me create a full-screen canvas with falling green katakana glyphs, fading trails, and a brighter leading character. Let me write the index.html file.

Let me verify the file works by checking it with node or just verifying content. The file is self-contained, no external resources. Good. Let me do a quick sanity check that the file exists.
Created `/workspace/index.html` — a self-contained Matrix digital rain effect. **How it works:** - **Full-screen black `<canvas>`**, auto-sizing to the window and debounced on resize. - **Columns of falling katakana** from a charset (katakana + a few Latin/digits/extras), each column with randomized width, speed, and a staggered start so the rain isn't a uniform grid. - **Trailing fade**: each frame is overlaid with a translucent black rect, and up to 8 glyphs behind each head are drawn with decreasing alpha, producing the classic motion trail. - **Brighter leading character** in pale green (`#c8ffe0`), with the trail in standard Matrix green at fading opacity. - Single `requestAnimationFrame` loop; columns reset to the top when they run off screen. Runs fully offline with zero external resources. Open `index.html` in any browser.
TAKE IT TO CODE

EVALUATION
Classic Matrix digital rain with green katakana columns, fading trails, and bright leading glyphs, animating continuously.

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.
