Let me verify the file was created correctly by reading it back.
Let me verify it's well-formed:

The file is created successfully. Let me give a summary of what was built.
The file is ready at `/workspace/index.html`. Here's what it implements: **Matrix Digital Rain** — a single self-contained `index.html` with: - **Full-screen black canvas** that resizes with the window - **Columns of falling katakana glyphs** (アイウエオカキクケコ… etc.) plus digits `0-9` - **Trailing fade** — each column draws a semi-transparent black overlay every frame (`rgba(0,0,0,0.05)`), leaving a fading trail of earlier characters - **Brighter leading character** — the head of each stream is bright white-green (`rgba(200,255,200,0.95)`), the second is slightly dimmer, and the trail fades from medium green to nearly black as it ages - **Organic randomness** — columns start at random offsets, have varying fall speeds, flicker characters occasionally, and reset randomly when they exit the bottom - **No external resources** — pure CSS inline, pure JS inline, no CDNs, no network requests

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.
