Create a single index.html that includes the Matrix digital rain.
write /tmp/ws/index.html (3776 bytes)

Quick sanity check — confirm that index.html exists. Done.
bash {"command":"ls -la /tmp/ws/index.html"}
toolResult

-rw-r--r--. 1 node node 3918 Aug 15 13:49 /tmp/ws/index.html

Wait, the size is 3918 but the write shows 3776 bytes — probably a difference in character count and byte count (katakana is multibyte). No problem. Done.

Created `/tmp/ws/index.html` — a fully self-contained Matrix digital rain: - **Full-screen black canvas** that fills the viewport, with resize handling and device-pixel-ratio scaling for crisp glyphs - **Katakana columns** (full katakana block plus digits) falling in per-column streams with randomized speeds - **Trailing fade** via a translucent black overlay each frame, so older glyphs dim gradually - **Bright leading character** rendered near-white-green (`#c8ffc8`) with occasional brighter green followers and flickering trail glyphs for the classic look - **Staggered resets**: when a column's tail clears the bottom, it restarts above the viewport at a new random speed No external resources — just open `index.html` in a browser.

Classic Matrix digital rain with green katakana columns, fading trails, and bright leaders animating continuously; input has no distinct effect.

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.
