Formats and portability

SVG

Agent-generated templates and backgrounds are standalone UTF-8 SVG documents.

• Bundled logos are embedded as data URLs.
• The file does not depend on the Glyphfield deployment after download.
• Dimensions are fixed in the root SVG.
• Text remains text unless the generator uses an image logo.
• Custom data URL images are embedded into the result.

Use SVG as the canonical API artifact.

PNG

Browser PNG exports rasterize the current composition at its defined dimensions. Moodboards can reach 4800 × 6000; templates use their production canvas sizes.

PNG is appropriate for social uploads, slide backgrounds, email graphics, and systems that do not accept SVG.

GIF

GIF exports contain a fixed color palette and frame rate. They are broadly compatible but less color-efficient than modern video formats. Glyphfield exposes palette size, frame rate, dimensions, and timing so the export can be tuned for its destination.

JSON

Glyphfield produces three useful JSON shapes:

1. Brand identity — the browser project’s shared foundation record.
2. Element brief — a catalog application resolved against an identity.
3. Artifact envelope — API metadata plus embedded SVG content.

All versioned agent responses include schemaVersion. Callers should retain and inspect it before assuming a future response shape.

Filenames

Generated filenames are deterministic from the project, generator, and output dimensions where possible. A caller may rename downloaded files, but should preserve the extension that matches mimeType.

Fonts

Browser moodboards embed their bundled font dependencies before rasterization. One-off local font files are session-local and are not available to the HTTP generator. API SVG uses its documented font stack unless the generator embeds a supplied image.
