note: >-
  kelvin publishes no price, no tier table and no self-serve checkout. There is no
  /tarifs, /prix or /pricing page — all three return 404 — and none of the 55 marketing
  URLs in sitemap.xml is a pricing page. Every commercial path on the site funnels to
  "Demander une démonstration" or a contact form, and account creation
  (/creer-un-compte-kelvin) leads to a sales-qualified onboarding rather than a
  published plan. This is a sales-gated B2B SaaS sold to renovation companies,
  artisan networks, CEE delegatees and estate agencies; plan_count: 0 is the accurate
  measurement, not a gap in the search.
offers_named_without_price:
  note: >-
    The API specification does name commercial offers, because entitlement is enforced
    per offer at the 403 boundary. These are product packages, NOT priced plans — no
    amount, quota or billing period is published for any of them.
