/*
  SIGNAL YELLOW RULING
  Signal Yellow appears exactly once per full-bleed surface. On Bond Paper it is
  the counter line inside the header bell. On Vault Green it is the fixed 72px
  rule in the CTA strip. It is never text, a text background, or a hover state.
  The thanks-page bell trades its yellow counter line for yellow strike ticks
  during the single motion sequence, so both never appear at once.
