QA

2. in peak-design-system, yarn link '@wealthbar/peak-design'
3. Fire up PDS
4. On tables page, links in table should shift to a slightly darker colour on mouseover
5. On modals page, the modal 'card' should have a fade-in / fade-out effect. It still slides, but it should also fade while sliding.
