/* ==========================================================================
   BoostaMe — component primitives
   Every value here comes from boostame-tokens.css. No literal colours, sizes,
   radii or durations. If a component needs a value that does not exist as a
   token, the token is missing -- add it there, not here.

   Namespaced `.bm-` so these coexist with Bootstrap 4 in the admin without a
   specificity war during the migration.
