User docs build fails: docs/screenshots/README.md has no title

[cewert]

What happens

Building the user docs from current jellyrock/jellyrock main fails:

[InvalidContentEntryDataError] docs → screenshots/readme data does not match collection schema.
  title: Required

Reproduced on 2026-09-14 with a fresh clone of this repo, npm ci, and npm run build:user (the same path deploy.yml runs), against jellyrock main at 9469f68.

Why

shared/fetch-docs.mjs copies docs/screenshots/ into src/content/docs/screenshots with a plain fs.cpSync. Only files under docs/user go through copyMarkdownWithFrontmatter, which adds the Starlight title. docs/screenshots/README.md is a generated gallery page with no frontmatter, so the content schema rejects it.

When it started

docs/screenshots/README.md was added in jellyrock 66021624 (2026-06-10). The last successful deploy of this repo was on 2026-06-09, so no deploy has run since the file appeared. The next one will fail at this step.

Possible fixes

• Copy only the image files from docs/screenshots (the markdown pages reference the images, not the README).
• Or skip *.md when copying that folder.

Deleting the file from the copied content lets the build finish (verified locally).
