  npm registry metadata + published tarball contents for @jet2/designsystem.*
  (fetched 2026-07-28); DNS and HTTP probe of design.jet2.com.
summary: >-
  Jet2 operates a real, named first-party design system — the Jet2 Design
  System — with published npm artefacts and a hosted documentation portal at
  design.jet2.com. It is the only genuinely public first-party developer
  surface Jet2 has. It is also gated and dormant: the documentation portal
  requires a Supernova login, and both npm packages were last published in
  April 2024. These are internal web-UI components for Jet2's own consumer
  properties, NOT embeddable components for an API (there is no Jet2 API to
  embed against), so this artifact records what exists rather than implying a
  developer-facing component offering.
documentation:
  url: https://design.jet2.com/
  status: gated
  platform: Supernova
  evidence: >-
    design.jet2.com is a CNAME to colossal-opossum-peach.custom.supernova-docs.io
    (63.35.34.86). A browser-shaped request returns HTTP 302 to
    https://default.supernova-docs.io/auth/login, which redirects to
    https://auth.supernova.io/login?...&docs_domain=design.jet2.com — an OAuth
    authorization-code + PKCE login. Non-browser clients receive HTTP 400
    {"error":"Not supported on older browsers. Please upgrade to a modern
    browser."}. No content was read; nothing about the portal's contents is
    asserted here beyond its existence and its login wall.
source_control:
  url: https://jet2tfs.visualstudio.com/Jet2Digital
  status: gated
  platform: Azure DevOps
  evidence: >-
    Both npm packages declare repositories under
    jet2tfs.visualstudio.com/Jet2Digital/_git/. Requests to the organisation and
    repository URLs return HTTP 203 (Azure DevOps anonymous-access rejection) —
    the repositories are private. This is Jet2's source-control home; there is no
    public GitHub organisation.

  note: >-
    Seven brand themes shipped side by side. "flights" and "holidays" map to
    Jet2.com and Jet2holidays; city, indulgent, vibe and villas correspond to
    Jet2holidays product lines; "global" is the shared base. Verbatim from the
    published tarball's directory structure — no interpretation of unpublished
    intent.
- family: React component library
  package: '@jet2/designsystem.library'
  loader: ESM/CJS bundle (dist/main.js), React 18 peer dependency
  built_on: react-aria-components
  components:
  - name: Button
    path: dist/components/buttons/Button
    typed: true
  note: >-
    Exactly one component is present in the only published version (0.0.2). The
    shipped README.md is the unmodified "React + TypeScript + Vite" scaffold
    boilerplate. Recorded honestly as an early or abandoned public release.
gaps:
- No public changelog, versioning policy or release notes for either package.
- No public Storybook (storybook.jet2.com and designsystem.jet2.com are NXDOMAIN).
- No contribution guide, licence file beyond the ISC declaration, or issue tracker reachable without a Jet2 Azure DevOps account.
- Neither package has been republished since April 2024.
