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.

**Considering resize implications** I’m noticing that when I resize, I need to reinitialize the columns, and clearing seems to prevent stretching. It feels like I need to write this down to remember it better. I want to ensure that I address this properly, as it's important for maintaining the layout or functionality. It's a small detail, but those tend to make a big difference! I'll keep this in mind for future adjustments.

**Verifying screenshots and reports** I see that the screenshot looks correct, but the resizing hasn't been verified yet. The user mentioned that some reports need checking and that they are unverified. I want to make sure we’re clear and concise in this communication since clarity is important for making sure everything is accurate. I’ll focus on addressing any outstanding issues regarding the reports to ensure the user has all the information they need.
Created `index.html` with animated digital rain and Pause/Resume and Restart controls. Checked the animation at several moments, pause and resume, restart, and the browser console. Viewport resizing and long-running recycling were not tested interactively.
