Create the Matrix digital rain effect on a full-screen black canvas: columns of falling green katakana glyphs with a trailing fade and a brighter leading character.

**Planning HTML creation**

I need to create an index.html file. It seems like a good first step for a web project. Before I dive in, it could be helpful to inspect the directory to see what other files or structures are already in place. This way, I can ensure that I'm organizing everything effectively. With a clear view of the directory, I can create a solid foundation for the index.html file. Let’s get started!
bash {"command":"pwd && ls -la"}
toolResult

/tmp/ws total 0 drwxr-sr-x. 2 node node 6 Aug 1 17:49 . drwxrwsrwx. 3 root node 16 Aug 1 17:49 ..

**Planning index creation**

I need to start creating an index that likely satisfies a visual requirement. I’ll want to write it out, considering maybe using a full-screen canvas that’s responsive, with some animations. Incorporating katakana characters and trails could be interesting. I might think about adding subtle controls too. The user has asked about the effect, so I need to keep everything in a single file, ensuring there are no external dependencies, and aim for a polished look.
write /tmp/ws/index.html (3696 bytes)

Successfully wrote 3696 bytes to /tmp/ws/index.html

Classic Matrix digital rain with green glyphs, trailing fade, and self-animation; inputs don't alter behavior beyond continued animation.
