// Auth : aucune — Cloudflare peut rate-limiter en test mais pas en prod avec cache 30min
// Timezone : 55 = UTC
// Scrape investing.com economic calendar (inflation events).
// Uses the AJAX endpoint which returns HTML inside JSON.

// Mapping confirmed by user:

// "CPI (MoM)" = Inflation Rate MoM → cpiMoM
// "Core CPI (MoM)" = Core Inflation Rate MoM → cpiCoreMoM
