Adobe Photoshop UXP Plugin API

The modern plugin development platform for Photoshop, replacing the legacy CEP framework. UXP (Unified Extensibility Platform) is powered by a V8 JavaScript engine supporting ES6+ and provides Spectrum design components for building panels and dialogs using HTML, CSS, and modern JavaScript. Plugins access a rich Photoshop DOM API for interacting with documents, layers, and actions, along with platform APIs for file system access, network I/O, clipboard operations, and more.
