S2 because this is barely readable with this theme and possibly entirely unreadable with others.

Attachment: Bug 2017149 - Add high contrast mode styles and keyboard focus for the smart window Ask button r=pdahiya,jlewis

Add prefers-contrast styles for #smartwindow-ask-button-inner to improve accessibility in high contrast mode. Removes the gradient background and individual child outline borders, replacing them with a single outline on the wrapper and custom HCM colors for default, hover, and active states in
both closed and opened (sidebar-is-open) configurations.

Also makes the button keyboard-focusable via -moz-user-focus: normal and adds a double-ring focus indicator.
