/*
  Gamma CRO — shared styles.

  Same visual system as nitro.training and the Minerva landing page: warm paper
  ground, Inter Tight, a large light display face, uppercase micro-labels,
  hairline-separated rows rather than boxes, and an inverted closing band. The
  three sites are sold together, so they should look like one company.
