Revisit box shadow on buttons/dropbuttons

Problem/Motivation

I'm open to the possibility others may disagree with this, but I'd like to have it discussed in an issue.
I've found that the box-shadow on buttons/dropbuttons look good in the Figma designs, but somehow don't translate well in their implementation in Claro. The shadow seems to close to the color of the button itself, which results in it looking misshapen or misaligned instead of having a shadow.

Current Appearance: Button With Shadow

Proposed Appearance: Button Without Shadow

Current Appearance: Dropbutton With Shadow

Proposed Appearance: Dropbutton Without Shadow

Proposed resolution

• Determine if this should be changed at all
• If it should be changed, determine if the box-shadow should be restyled or removed altogether
• Implement the change

Remaining tasks

User interface changes

API changes

Data model changes
