Edits project.ypf - opened from Project Editor. Sets up the page itself, before laying anything out in the Overlay Editor. Full schema: project.ypf.

Name & description

• Name - the project's display name. Distinct from the form's own title (shown on Input Form itself).
• Description - a short summary, shown on the project's yatate.app/library detail page if published there.
• Notes - free-form notes for yourself; not shown anywhere else in the app.

Canvas source

• Use base.pdf - page size, page count, and background come from a real PDF file at the project root. See base.pdf below to regenerate it, or replace it with your own externally-designed file.
• Generate from these properties - skip the physical PDF entirely; set a canvas size and background color instead, synthesized at render time.

Margins (generated-canvas mode only)

A purely visual guide in the Overlay Editor - they don't clip or reposition anything.

base.pdf

Reached from base.pdf's overflow menu on Project Editor. Generates a blank page at a chosen size/color and overwrites the current base.pdf - destructive, can't be undone. Only applies when the project uses a physical base PDF (see Canvas source above).

Existing blocks keep their exact position/size - if the new page size differs from the old one, re-check block positions afterward in the Overlay Editor.
