/*
  Stylesheet for the RVM3 home page. The MedSweep pages keep their own
  assets-style.css, which mirrors that app's theme; this one is RVM3's.

  Type is the same self-hosted Bitter and Karla already in fonts/ (SIL Open
  Font License 1.1, license text alongside the files). Nothing is loaded from
  another origin, and the CSP in _headers would refuse it if it were.

  The palette is a neutral ink on paper shared with Socket & Steel. RVM3 has no
  brand color of its own, so color is left to the app icons.
