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.
thinking
The user wants a Matrix digital rain effect - the classic green falling characters from the movie. Let me create a single self-contained HTML file with: 1. Full-screen black canvas 2. Falling columns of katakana characters 3. Green color scheme with trailing fade 4. Brighter leading character at the top of each column I'll use a canvas element with JavaScript to animate the effect. Key design decisions: - Use canvas for performance - Katakana Unicode range: U+30A0 to U+30FF - Each column should have a head position that moves down - Trail should fade by drawing a semi-transparent black rectangle each frame - Leading character should be bright white/light green, trailing ones darker green - Randomize character changes for that flickering effect Let me write this out.

The file has been written. Let me verify it's there.
The Matrix digital rain effect is ready in `/workspace/index.html`. Here's what it does: - **Full-screen black canvas** that fills the entire viewport - **Katakana glyphs** (U+30A0–30FF) plus some Latin/digit characters for authentic movie feel - **Leading character** glows bright white-green with a shadow blur halo - **Trailing characters** fade from bright green to dark green using per-row opacity decay - **Flicker effect** — random characters mutate their glyphs to create the classic "shimmering" look - **Varied column speeds and trail lengths** so the rain looks organic and unsynchronized - **18 FPS** frame rate with `rgba(0,0,0,0.07)` overlay each frame for a smooth fading trail - **Responsive** — resizes and re-initializes on window resize Open `index.html` in any browser to see the effect.

EVALUATION
Classic Matrix digital rain with green katakana columns, fading trails, and bright leading chars; animates continuously, unaffected by input as expected.

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.
