Images, logos, SVGs, and custom fonts all live flat in the project folder, alongside every other project file - no assets//fonts/ subfolder. Add them from Project Editor (drag-and-drop or Add Asset) - see Overlay Editor for how a block picks up a font.

Built-in fonts

Available in every project, case-insensitive - omit or use "Default" for the app's own default:

Cousine, IBMPlexMono, FiraSans, Lato, PTSans, TitilliumWeb, AlexBrush, Allura, GreatVibes, MrDeHaviland, Parisienne, Sacramento, CrimsonText, IBMPlexSerif, PTSerif, Spectral, Kalam, Pacifico.

The script-style families (AlexBrush, Allura, GreatVibes, MrDeHaviland, Parisienne, Sacramento) are also what a signature field's "Type" capture mode offers.

Which font wins

When a block references a font family by name:

1. A .ttf/.otf in this project's own folder.
2. A global fonts folder shared across every project (no in-app screen - drop files into Yatate/fonts in your OS's per-app support directory by hand).
3. The app's built-in default.

A custom font sharing a built-in name wins for that project. Only normal and bold weights are used, even if a font ships italic faces.
