rig.layout.master

Marks a rig.layout.page entity as a master page. Format when present.

Document pages apply a master via rig.layout.applied_master. Facing books typically keep a left and a right master; singles use side single.

Master content (headers, folios, frames) parents to the master page the same way as any page. Instantiation onto document pages is fulfillment.

Chrome text frames

A master child that carries both a rig.story.flow and a box is page chrome (folio, running header): hosts stamp it onto every page that applies the master, resolving {{page}} / {{pageCount}} / {{title}} / {{section}} tokens in the paragraph text per page. The flow's rig.layout.paragraph_style owns the type - size, alignment within the frame, paint, and alignToBaselineGrid - so chrome is document data, not host configuration. Each paragraph sets a single line; chrome does not wrap or overflow.
