**Developing Digital Rain** I'm focusing on the "Matrix digital rain" effect, aiming for an `index.html` file that is self-contained. The goal is no external resources, black background, green katakana glyphs in vertical columns, with trailing fade and a bright lead character. The `<canvas>` element seems key for this. **Refining Column Logic** I've been refining the column handling. I'm calculating the number of columns based on font size and screen width. Animation will use `requestAnimationFrame`. For the fade effect, I will be using a semi-transparent black rectangle, or adjusting opacity, to draw the trail. I'm focusing on the Unicode range for Katakana characters. I'm also planning to reset the character y-position to the top randomly.

The Matrix digital rain effect has been implemented in a single `index.html` file. It features a responsive full-screen canvas, trailing fade, and brighter leading characters using the Katakana Unicode range. You can open `index.html` in any web browser to view the effect.

EVALUATION
Classic Matrix digital rain with fading green katakana columns and bright leading chars, animates continuously; inputs don't add extra interactivity.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
