Enhanced CSV — one row per section header or content line. Columns (any order, header row required): type,section_type,role,name,heading,subtitle,body,image_url,image_width,font,size,weight,color,align,columns,gap,line_height,letter_spacing,pad_top,pad_bottom Row types: section — opens a new section. section_type is one of title, big-name, single-col, two-col, credit-block, block-list, text-image, image, text, spacer. Formatting columns on a section row become its defaults. title — for title sections: name=main line, subtitle=secondary line. name — for big-name sections: one big name per row. credit — for single-col / two-col / credit-block sections: role and name. block — for block-list sections: name=block title (rendered in quotes), body=multiple lines separated by |. Great for a film-style SONGS section. text — free body text (body). image — image_url, image_width. spacer — blank vertical space; size is height in px. Formatting cells on a content row override just that line. Empty cells inherit.
