{# The slide a deck opens on. No bands: a title slide carries no number, as a cover carries no folio. The copy is anchored low on the sheet, inset by the page margin like every slide's, under an accent rule; positioned, as the divider's is, because WeasyPrint ignores a cell's valign attribute. Anchored higher (#355), the band spans the sheet less a title band's height at each edge, and a cell set by CSS `vertical-align` places the copy in it. #}
