Customize, click the Ask Any AI block on your product template, and the
settings appear in the panel on the right.
Whatever you change applies to the widget on every product page.

Getting it to fit your theme
Two settings do most of the work: set Primary color to whatever your buttons
use, and Corner radius to match them. That's usually enough for the widget to
stop looking bolted on.
Leave Font on Theme font unless you've got a specific reason not to, since it
inherits your store's typography and stays matched if you restyle later. Leave
Maximum width and Internal padding at 0 too — both defaults are responsive,
and fixed values aren't.
