StockMarketAPI: Brand Image. Branded feature image for a document-only news source, by category. Public (no API key) so it can be embedded straight into an ``<img src>``; cached for a week. This is what `articles[].image_url` points to when `image_type == "source_brand"` — i.e. a source like ASX announcements, whose stories are PDFs and can never carry a scraped image of their own.
