LGTM, I do lean towards removing the snapshots but that's not a blocker.

This looks good to me! Only one very minor non-blocking question

Issue number: internal
What is the current behavior?
Card content has no encapsulation.
What is the new behavior?
Convert
ion-card-contentto Shadow DOM which improves consistency among components & CSP compatibility.Does this introduce a breaking change?
There should not be any breaking changes related to targeting inner elements since
ion-card-contentdoes not have any internal elements of its own. However, some user styles may break due to the removal of thecard-content-{mode}class or changes in selector specificity. Additionally, the styles targeting heading elements in card-content were removed. Users that wish to have custom styling for headings should add their own CSS targeting them.
