/* BuildOps — MTL brand theme.
   Brand tokens are carried verbatim from WhereAreYou (see MTL graphics/mtl-brand-guidance-app-theme.md)
   so the two apps look like one estate. What differs below the tokens is the layout: WhereAreYou is a
   phone-first app of big tap targets, and this is an operations dashboard of dense tables read on a
   desk. Hand-built CSS, deliberately — MTL does not use Fluent UI. */
