- favicon.svg: the mark vectorized (OpenCV contour trace of the
artwork, even-odd fill) -> crisp at any tab size, ~3KB. Set as the
primary <link rel=icon type=image/svg+xml> with PNG fallbacks.
- Deepen the green: same hue, full saturation, ~72% value
(#1DB800) and embolden faint anti-aliased strokes (alpha gamma)
so it no longer looks washed-out at favicon size.
- All PNGs (16/32/256, apple-touch, icon-512) regenerated to match.
