What the model said
I couldn't open the file in a browser to preview it (that action needed approval and got auto-denied), but here's what I improved: - Ring radius reduced 180→140 so ripples no longer risk clipping against the viewport edge at max scale (1.35×). - Ripple easing changed to a smoother custom cubic-bezier instead of plain `ease-out`. - Glow filter now tints the blur blue (via `feColorMatrix`) instead of a plain grayscale blur, and enlarged its bounding box (`-80%/260%`) so the stronger glow isn't cut off. Open `0.html` in a browser to check the result — let me know if you want a different color scheme, speed, or additional effects.
