Summary

The Bootstrap theme's user templates and the Blog article fallback used external placeholder services. via.placeholder.com has shut down, so those placeholders no longer load.

• Adds src/Layout/Images/image-placeholder.svg: a light grey 4:3 image with a simple sun-and-mountains shape, used for every photo slot regardless of its size.

• Adds src/Layout/Images/icons/icon-placeholder.svg: a dashed 80×80 square for icon slots. Core has no icon placeholders yet, it is there for themes that need one.

• Replaces all 9 external placeholder images:

  • img-fullwidth, image-l-image-r (2), image-l-text-r, text-l-image-r: via.placeholder.com
  • test.html: 3 placehold.it references (image, data-src, background url())
  • Blog Article.html.twig: the fallback for an article without an image, now {{ THEME_URL }}/Core/Layout/Images/image-placeholder.svg

• Fixes copying a page that contains one of these placeholders: Add::getOriginalPage() copied every user template image that is not a full URL from the upload folder, so a theme asset made Filesystem::copy() throw. It now only copies images whose src is in Files/Pages/UserTemplate.

Ported from sumocoders-be-2026, where the same SVGs replace the placeholders in the Custom theme.

Test plan

• No external placeholder URL left outside node_modules, vendor and built Core folders
• twigcs on the Blog template: no violations
• CI
• Insert the full-width image user template in the page editor and check the placeholder shows
• npm run build copies the SVGs to Core/Layout/Images
• Copy a page that uses a user template with a placeholder image

**Copying pages with placeholders fails**

When a page containing one of these user templates is copied before its placeholder image has been replaced, `Add::getOriginalPage()` treats these non-HTTP image paths as uploaded user-template files, then `Filesystem::copy()` tries to copy `image-placeholder.svg` from the user-upload directory, where it does not exist, aborting the page copy.

Exclude theme asset paths from the uploaded-image copy logic, or otherwise preserve them without attempting to copy them from the user-upload directory.

**User-template placeholders appear broken**

When the deployment serves built theme assets from Core but does not expose the source tree, the template image URLs point to the source-tree path, which the deployment does not serve, so the browser cannot load the placeholders.

Point both template images at the built theme assets under Core/Layout/Images.
