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.

I'll create a Matrix-style digital rain effect with the requested features. Let me build this in a single HTML file with inline CSS and JavaScript.

I've created a Matrix-style digital rain effect in a single HTML file. Let me check the behavior:

{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing."],"dom":"Pause Restart","images":"attached"}
I see that the animation isn't showing up yet. Let me check the console for any errors and make sure the canvas is properly initialized.

{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing."],"dom":"Pause Restart","images":"attached"}
I see that the canvas is not displaying the animation. Let me check the DOM structure and make sure the canvas is properly sized and positioned. Let me inspect the DOM and make adjustments to ensure the animation works correctly.

I see the issue. The canvas is not rendering the animation properly. Let me fix the code to ensure the animation works correctly by making the following changes: 1. Ensure the canvas is properly sized and positioned 2. Fix the character rendering to ensure visibility 3. Improve the animation logic Let me update the code:
{"path":"index.html","edits":[{"oldText":"<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n <meta charset=\"UTF-8\">\n <meta name=\"viewport\"Successfully replaced 1 block(s) in index.html.
Let me reload the page to see if the changes have taken effect:

{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing."],"dom":"Pause Restart","images":"attached"}
I see that the animation is still not showing up. Let me check the console for any errors and make sure the canvas is properly initialized. Let me inspect the DOM and make adjustments to ensure the animation works correctly.

I see that the animation is still not showing up. Let me try a different approach by simplifying the code and making sure the canvas is properly initialized. Let me update the code to ensure the animation works correctly:
{"path":"index.html","edits":[{"oldText":"<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n <meta charset=\"UTF-8\">\n <meta name=\"viewport\"No changes made to index.html. The replacement produced identical content. This might indicate an issue with special characters or the text not existing as expected.
I see that the changes I made were not applied because the text was identical. Let me try a different approach by simplifying the code and making sure the canvas is properly initialized. Let me update the code to ensure the animation works correctly by making a more significant change to the code structure:
{"path":"index.html","edits":[{"oldText":"<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n <meta charset=\"UTF-8\">\n <meta name=\"viewport\"No changes made to index.html. The replacement produced identical content. This might indicate an issue with special characters or the text not existing as expected.

10 minutes have elapsed. At most 5 minutes remain. Finalize the output as soon as possible: save index.html now, fix only essential issues, and finish.
