/*
  Design direction: a race-control timing tower, not a marketing site.
  F1 timing towers are dense, monospaced, high-contrast displays built to
  be read at a glance from across a garage — that's the reference point,
  not a generic dashboard template.

  Palette: dusk-storm, not the usual cream/terracotta or near-black/acid-
  green AI-default pairings. Deep blue-charcoal ground, a warm amber-gold
  accent (storm light through cloud cover — ties to "Daze of Thunder"
  without being literal), a cool slate for secondary text.
