Open formats

Lattice chooses common, inspectable formats according to the resource:

Resource	Canonical direction
Page	Markdown with optional frontmatter
Canvas	JSON Canvas with a documented Lattice profile
Mutable data app	SQLite package with readable manifests and views
Analytical dataset	Parquet, queried locally with DuckDB
Notebook	Jupyter ipynb with open runtime adapters
Ordinary file	The file’s native format

Rich UI is an editor or view over these resources, not a replacement for them. Portable previews and honest fallbacks should accompany formats that require a specialized renderer.

See the canonical workspace formats specification.
