Public, unauthenticated badge payload for the embeddable "Audio on Storyflo" pill. Drop-in HTML snippet on a publisher's own site (single <iframe>) fetches this to render instant social-proof: total lifetime listens + the timestamp of the most recent rendered briefing.

CDN-cacheable for 5 minutes. Returns 200 with zeros when the publisher is unknown so the badge always renders something — publishers who paste the snippet before claiming still see the storyflo branding and a click-through to the homepage with their slug as ?ref= for attribution.
