VAST 4.x compliant ad response — Triton / AdsWizz / Magnite hit
this for fill on any audio impression. Currently returns a single
InLine creative based on our existing stitched_creative selection;
chains to a no-fill response when no creative matches.

Query params (per IAB OpenRTB-Audio convention):
  slug    — article slug being played
  vertical — content category for matching
  gdpr_consent — TCF v2.2 consent string
  gpp / gpp_sid — GPP signal

For SSPs that do programmatic bidding, the upstream RTB integration
lands later (year-2 work). This endpoint covers the static-VAST
