generate-cover-image

Generates a 1200x630 PNG cover image from what an article means, using the bundled prompt (dark, futuristic, human-and-system artwork with no text) and the Canva connector. For jeffbaileyblog it builds or overwrites the article's own Canva cover design from the jbb-feature-image-template brand template, sets the title, files and exports it beside the article, and sets the Hugo cover front matter; it also covers category pages and runs in batches for many covers at once. Use whenever someone wants a cover, hero, featured, header, OG, social-preview, or share image for a blog post, article, or category page, says /write:cover, asks to redo or refresh an existing cover, or when write-article finishes a jeffbaileyblog draft, even if they don't say "cover".
