  render-image.html — Goldmark image render hook (theme-portable image fix).

  doxtr-hugo emits each rendered asset (``math-<hash>.png``,
  ``diagram-<hash>.svg``) and each co-located authored image as a *bundle-local*
  Markdown reference: ``![alt](math-<hash>.png)``. Goldmark's default image
  renderer copies that destination verbatim into ``<img src="math-<hash>.png">``.
  That only resolves while the page is served at its own bundle URL. The moment a
  theme renders a page's *full content* somewhere else — a blog-style home feed,
  a section ``list`` page, a paginated archive — the browser resolves the bare
  filename against *that* URL and the image 404s. (Archie's home feed, Risotto's
  section lists, and similar themes all do this.)

  This render hook makes bundle-relative image references resolve correctly no
  matter where the page content is embedded: a bare filename is looked up as a
  *page resource* of the page that authored it and rewritten to that resource's
  absolute ``.RelPermalink``. External/absolute/root-anchored URLs are passed
  through unchanged.

  A site-level ``layouts/_markup/`` render hook takes precedence over a theme's
  own hooks but does NOT shadow the theme's page templates, so shipping it is
  safe in both the full skeleton and the content-only (theme drop-in) emit.
