API types

Import exported types from codeboard-studio in TypeScript. JavaScript callers use the same object shapes. These declarations describe inputs and returned artwork; they are not instructions to hand-write a project container. Use handles and production methods to edit stored values.

Positions are canvas units; rotation is radians; pressure and opacity use 0–1; pen timestamps use milliseconds; timeline positions use integer frames. Inherited and helper structural types are included for reference; not every helper type is a named package export.
