I compiled a PDF summary report at report.pdf. Please render an inline preview directive for this PDF file so I can read it inside our conversation.

Inline previews

When the user should see an HTML demo or a Markdown document inline in the assistant message, write (or update) a source-relative file, then emit this message directive as its own block (not inside a fenced code block):

::inline-vis{file="demo.html"}
::inline-vis{file="notes.md"}

Omitting source defaults to the workspace. Explicit source="workspace" is equivalent. For a read-only thread-storage artifact, write the document to $BB_THREAD_STORAGE/reports/result.html, then emit its storage-relative path:

::inline-vis{source="thread-storage" file="reports/result.html"}

Rules

source is optional and must be workspace or thread-storage.
file is relative to the selected source (e.g. demo.html, charts/out.html, notes.md). Workspace paths are relative to the current workspace; thread-storage paths are relative to $BB_THREAD_STORAGE. Never put an absolute path in the directive.
height is optional and sets the preview height in pixels. It must be a whole number from 120 through 1200; omit it for the 224px default.
.html, .htm, .md, and .markdown files are accepted.
Inline and external CSS/JavaScript are supported in HTML. Remote images, fonts, media, fetches, and WebSockets are also allowed subject to normal browser CORS, mixed-content, and remote-server policies. Scripts execute in an opaque-origin iframe and cannot access the bb page, cookies, or storage. Markdown uses BB's renderer with raw HTML disabled.
Keep files small (under the sidebar preview's 5 MiB document limit).
Emit the directive only after the file exists on disk in the selected source.
Prefer thread-storage for read-only generated reports and other artifacts that should not modify the workspace.
Do not put the directive inside backticks or a markdown code fence, or it stays literal text.
