The web orb looks like glass because backdrop-filter refracts the
background through it. Android has no backdrop-filter, so the old
approach painted an opaque amber ball with harsh colors (#FFF1D6,
#8D4F00 at 85% alpha) that looked like a sticker, not glass.
New approach: very low alpha accent tint (15-22%) so background
blobs bleed through, creating a lens effect. Light source at
top-left with subtle white radial, warm accent bleed bottom-right,
gentle bottom shadow for volume (not 85% dark brown). Elliptical
specular highlight instead of circular. Double rim (outer hairline
+ inner inset) matching the web's box-shadow approach. Caustic
sweep reduced to 25-30% alpha (was 50-65%).
