      note: >-
        Validated against an allowed character set before use; blank or unsafe values
        (e.g. "../evil") fail the tag rather than building a URL.
    behaviour:
    - Injects the tracking script exactly once per run (single-fire guard on both success and failure callbacks).
    - Declares an explicit GTM inject_script permission scoped to https://assets.tvspix.com/.
    - Trims and normalises the tracking id before building the URL.

    docs_note: >-
      metadata.yaml points both `homepage` and `documentation` at the tvScientific marketing
      root — there is no dedicated implementation guide for this tag on any public page.

      Verbatim from the template: "The Universal Site Pixel (USP) must be the first script
      that loads on your website prior to triggering any event-related functions."

    detail: >-
      tvScientific's own integrations page describes affiliate partners connecting "through
      streamlined postback-based conversion tracking" (Avantlink) and lists MMP, affiliate,
      conversion-tracking, measurement and audience integration categories. The postback
      mechanics themselves are documented by the PARTNERS (Adjust, Ascend/Partnerize,
      Rockerbox, Singular), not by tvScientific, and no first-party payload schema, event
      catalog or webhook reference was found — so no AsyncAPI or Webhooks artifact is
      written and no Webhooks pointer is emitted.
