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 create a Matrix-style digital rain effect in a single self-contained HTML file. Let me break down the requirements: 1. Full-screen black canvas 2. Multiple independently moving columns of green katakana glyphs 3. Each column has a brighter leading character and fading trail 4. Vary column speed and start position 5. Recycle columns after they leave the bottom 6. Pause/Resume functionality (freezes animation) 7. Restart functionality (clears columns and trails) 8. Resize canvas to fit viewport 9. No external resources, no network requests Let me write this complete HTML file with inline CSS and JavaScript.
I'll create a complete Matrix-style digital rain effect in a single self-contained HTML file.
