Additional context

Background info

• W3 wai-aria-1.1
• Vox Accessibility Guidelines a11y
• @storybook/addon-a11y - on github
• DrafJs - DOM and Accessibility

Identify what is needed to

• make it keyboard navigable
• accessibility hierarchy of elements to move in and out of the text area (eg using h1 for title? to move to top level player controls? or a hidden anchor link)
• test with Mac OSX default screen reader
• DraftJs accessibility)
• figure out if the accessibility interaction to edit text, play media etc.. effects the current UX and whether we need to revisit that with those constraints
