  Millimetric pricing tiers, read from the public pricing section of the marketing site
  (re-read 2026-08-13, HTTP 200). Usage-metered on events per month with tiered data
  retention, project count, support channel and MCP entitlement. Self-serve on every tier —
  the page states "No 'contact sales'. No per-seat fees. Just events." Above 10M events/month
  there is no published tier: the page says "Need more? Email hello@millimetric.ai — we'll
  quote you in plain English."
