#####Problem
The layout and component spacing of the different views and elements of the Mismatch Finder app were defined using `$dimension-layout` and `$dimension-spacing` WiKit tokens, which consume values in `rem` and `em` respectively.
We need to replace these legacy styles, but the new Wikimedia design system (Codex) doesn't include equivalent tokens with these same units of measurement, which we prefer to use due to consistent scaling/accessibility and predictability reasons. Instead, it provides only spacing tokens in `px`.
#####Solution
In order to unblock the migration project, we'll need to create a set of reusable, less spacing variables to replace existing WiKit `$dimension-layout` and`$dimension-spacing` tokens.
#####Acceptance criteria
[] WiKit layout and spacing tokens used to style the Mismatch Finder app are replaced by custom variables
