#### Description
This should be one of the final tasks completed for the new Impact Module. It is basically a reminder for us to meet our Accessibility goals and check a few other edge bases.
#### Acceptance Criteria
**Accessibility Goals:**
[] All Positive Reinforcement features pass Chrome Lighthouse and QA Accessibility scan
[] All features we work on for Positive Reinforcement are navigable by keyboard
[] Impact Module graphs have alt text that conveys the basic meaning of the chart
**Edge cases:**
[] If a thumbnail doesn't load, (certain SVGs are not being rendered properly as thumbnails) then we instead show the standard placeholder thumbnail image. Example: {F35320879}
