Storefront design tokens
The global stylesheet owns surface, ink, accent, spacing, and type tokens. Light and dark are separate art directions. Local Manrope and Libre Caslon Display font files ship with their open font licenses.
Theme preview presets
Each registered preview declares its allowed pages, appearance modes, typography, accents, and density settings. An unsupported combination is rejected or normalized with a visible explanation. Preview styles never apply to the storefront.
Content before components
Use the editorial catalog to change copy, intended uses, included templates, and limitations. Components consume that model rather than owning product text. The optional EmDash profile uses native published content and menus.
Motion with restraint
The opening composition uses bounded CSS motion. Reduced-motion settings remove spatial transitions. Interactive previews load only where needed, and comparison on a small screen uses one readable pane at a time.
