fix(android): ring at circle edge (background layer) + smaller grid

Move the metallic ring into the background (renders to the mask edge, unlike the
foreground which is cropped to the safe zone) so the border is finally visible
at the circle's rim; shrink the grid to ~0.55 so the mark isn't too big.
