Instances of this component in production

• Prescriptions

Accessibility considerations

• The card's type and place in the list (ex. prescription 1 of 1) should be called out first by the screen reader. The screen reader should call out each individual touch target by its respective type (button, link; etc) along with its respective a11y hint.
• Keyboards and Voice Access/Voice Control should navigate through each line item separately
• Keyboards and Voice Access/Voice Control should navigate each touch area separately
• Touch target UI should have clear and distinguishable areas/borders
