A GeometryReader hands its content the full proposed frame and pins it
top-left, so the Lock Screen card sat high instead of vertically centred
when the activity container offered extra height. Wrap the branch in
.frame(maxWidth:.infinity, maxHeight:.infinity, alignment:.center).
Also darken the pump circle to 82% of the raw fuel tint (mix 18% black) so
the white pump symbol keeps contrast against bright Lock Screen/card, esp.
for the light yellow premium / cyan diesel palette colours.
