v1.2.4 - Letterhead from sample

What's new

• Letterhead lookup: chat Files API first, then /mnt/uploads if the file id cannot be read
• Accepts .docx and .dotx
• Injects missing Word styles (Heading 1-4) so Italian templates do not drop titles
• Keeps header, footer, watermark, top spacing and the address block from the sample
• Reuses body and heading fonts from the sample (e.g. Garamond / Baskerville)
• Tool description tells the model to call generate_document, not execute_code

Notes

• Set letterhead: "Filename.docx" in the frontmatter
• Do not set a programmatic cover together with a letterhead
• Paste generate_documents.py into Workspace → Tools to update an existing install
