Created a self-contained `index.html` with the Matrix digital rain effect: - **Black full-screen canvas** with falling green katakana, Latin, and numeric characters - **Trailing fade** for each column, with the leading character brighter - **Dynamic resizing** to fit the window - **Randomized speed** and character changes for organic movement - **No external dependencies**—pure HTML/CSS/JS Open the file in a browser to see the effect. Adjust the `chars` string or styling in the `<style>` tag to customize.
