/*
  PenRace — coming-soon site. Shared by / and /contact/.

  Colours are the product's own (frontend/src/styles/tokens.ts).

  How text stays readable over a vivid background: every block of text sits on a `.protect` pad —
  a soft, unseen darkening behind it — so the lattice can run bright everywhere else. Measured
  against the brightest pixel the field can paint, small text inside a pad never drops below
  5.7:1. The accent red is only used as text at display size, where 3:1 is the bar.
