Design system · public viewer

113 real app-owned fixtures from Focus, Great Circle, stethem, Reads and Bandit are packaged as static, isolated previews. The surrounding viewer and 84 independent reference studies retain their own styles. Fixture data is deterministic; this is not a live-service or production-health claim.

Public fixture preview: EPUB states use authored sample text. Real EPUB parsing is not included; uploaded files are not parsed by this preview. The release-only adapter rejects unexpected parser calls. Original app source and registered fixture loaders remain unchanged; epubjs and its dependencies are not distributed in the Focus bundle.

Capture generation and local review exports are intentionally excluded. Use the local checkout for capture tools. Source app files have not been changed.

Robin Stethem’s original design-system code, documentation and neutral authored specimens are MIT licensed. Application source, snapshots and packaged app previews retain their own terms. Reference studies retain their upstream MIT licenses and attribution. Third-party trademarks, logos, fonts, images and other assets are excluded from Robin’s grant; included fonts retain their OFL notices in previews/stethem/fonts.

Hosted deployments must send Access-Control-Allow-Origin: * for these public static files. Previews retain sandbox="allow-scripts", without same-origin, top-navigation, storage, popup or form privileges. Existing fixture browser/OS limitations still apply.
