  Package-registry surface for Back Market. Back Market publishes NO first-party client SDK
  for its seller API in any language — the API Guidelines at api.backmarket.dev document raw
  HTTP only, and no SDK/library links appear in the docs. The one clearly first-party API
  package on a public registry is the Spectral ruleset Back Market uses to govern its own API
  designs (@backmarket-api/rulesets, published from github.com/BackMarket/api-rulesets and
  already harvested into rules/ in this repo). Community-maintained wrappers exist but are
  not endorsed by Back Market.

    Back Market's own Spectral ruleset for API design governance. Not a client library —
    it is the linting contract Back Market applies to its OpenAPI definitions. Harvested
    into rules/back-market-rules.yml + rules/functions/ in this repo.

notes: >-
  The npm scope @backmarket/* holds a set of Vue UI micro-components (button, carousel,
  modal, sticky, ...) last published in 2018 by a Back Market front-end engineer. They are
  storefront design-system experiments, not API client libraries, and are not documented or
  supported as part of the seller API — recorded here for completeness, not counted as SDKs.
  Because no official client SDK exists, no `SDKs` pointer is wired in apis.yml.
  The github.com/BackMarket organization exists (HTTP 200) but exposes zero public
  repositories — github.com/BackMarket/api-rulesets, referenced by the npm package
  metadata, is not publicly readable. Two Postman teams whose handles contain
  "backmarket" answer 200 (postman.com/backmarket-mobile,
  postman.com/backmarket-jira-782969) but neither could be verified as Back Market-operated
  or as carrying a seller-API collection, so no `Postman` pointer is wired.
