See Notion for complete spec.
We employ a base-10px grid for consistent vertical rhythm.
Spacing units are set in multiples of 10px.
When building layouts and components, palette hooks into a Theme file for returning values. This allows us to constrain the possibilities available to a component to only what's defined in our spacing system and thus reduce drift.
This means that in practice one should rarely use concrete pixel values:
Since units use ten pixels as the base,
5px (and so on).
