/*
  Styles for markdown rendered into the notes page.

  These live outside the component on purpose. Angular's emulated view encapsulation rewrites a component's selectors
  to require a scoping attribute, and elements injected through [innerHTML] never receive one — so `.markdown pre`
  written as a component style silently matches nothing. Making them global is the fix that does not rely on the
  deprecated ::ng-deep.
