{{- /*
  edit-page partial

  Renders a link to edit the current page's source file on GitHub. Visitors
  without write access are offered GitHub's standard "fork and propose changes"
  flow automatically when they follow an /edit/ link, so no extra handling is
  needed here.

  This partial is the single source of truth shared by the `edit-page`
  shortcode and by any hook (for example `content-after`) that wants to render
  the link automatically.

  Accepts either a Page directly, or a map:
    - page    (required) the Page whose source file should be edited.
    - branch  (optional) overrides the configured branch for this call.

  Configuration (under params.ananke.shortcodes.edit_page):
    - repo_url     (required) Base URL of the GitHub repository, e.g.
                   "https://github.com/owner/repo". When unset nothing renders.
    - branch       The branch to edit. Defaults to "main".
    - content_dir  The directory the content lives in inside the repository.
                   Defaults to "content".
    - target       Link target. Defaults to "_blank". Set to false to open in
                   the same window.
