Prompt for this run
Build an animated Matrix-style digital rain effect on a full-screen black canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Draw multiple independently moving columns of green katakana glyphs, each with a brighter leading character and a fading trail. - Vary column speed and start position. Recycle columns after they leave the bottom so the effect continues without accumulating off-screen state. - Provide Pause/Resume and Restart. Pause freezes the animation; Restart resets the columns and clears previous trails. - Resize the canvas and column layout to fit the viewport without stretching an old screenshot or leaving an uncovered strip. - Use locally available fonts and procedural drawing; no external fonts or images. Choose glyphs, brightness, and timing freely. Verify: Sample the animation at several moments to inspect independently moving columns, brighter leading glyphs, and fading trails. Pause and resume to check that the image freezes and continues, then use Restart and check that old trails are cleared.

The user wants me to build a Matrix-style digital rain effect in a single `index.html` file. Let me create this with: 1. Full-screen black canvas 2. Green katakana glyphs falling in columns 3. Brighter leading characters with fading trails 4. Varying column speeds and start positions 5. Column recycling (recycle when they leave bottom) 6. Pause/Resume and Restart buttons 7. Resize handling 8. No external resources Let me write the complete file and then test it in the browser.

Good, the file is written. Now let me open it in the browser to verify the animation works correctly.
Now let me open it in the browser and verify the behavior:
{"action":"screenshot"}Frame 1, +0ms
[Browser image supplied to model]
{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing."],"dom":"Pause\nRestart\nCOLUMNS: 66 | STATUS: RUNNING","images":"attached"}

The Matrix rain is rendering but it's only appearing in a narrow vertical band in the center rather than filling the screen. The issue is likely with the canvas resize handling and column positioning. Let me look at the code more carefully and fix the issues: 1. The canvas appears to be centered but not filling the viewport 2. The columns are only appearing in a small region Let me read the current file to understand the issue.
Let me read the current file and check the resize/logic: read /tmp/job-TU9fup/index.html
