      # This is a pnpm workspace. npm does not read pnpm-workspace.yaml, so `npm ci`
      # silently skips every per-package dependency and the suite fails on imports
      # that are correctly declared.
      # No `version` here on purpose: package.json declares `packageManager`, and
      # specifying both makes the action fail with ERR_PNPM_BAD_PM_VERSION.

      # mermaid-export renders through puppeteer, which needs a real Chrome. The
      # browser normally arrives via puppeteer's postinstall script, which does not
      # run here, so eleven of its tests failed with "Could not find Chrome (ver. …)".
      #
      # Filtered to the one package that depends on puppeteer. A bare `pnpm exec` runs
      # from the workspace root, where the binary does not exist, and fails with
      # "Command \"puppeteer\" not found" before it reaches the package that has it.
