## What it is
Decker is a multimedia platform and sketchpad for creating and sharing interactive documents with sound, images, hypertext, and scripted behavior, inspired by HyperCard. It ships as a native C/SDL2 application, a single-file web app, and a standalone interpreter (Lilt) for its scripting language Lil.

## Use cases
- build interactive documents with images, sound, and hypertext
- create HyperCard-style stacks and multimedia sketches
- prototype small interactive apps or games with a simple scripting language
- author and share self-contained HTML decks on the web
- script general-purpose tasks with the Lil interpreter (Lilt)
- learn programming through a retro creative computing environment

## When to choose
- you want a HyperCard-like multimedia authoring tool that runs natively or in a browser
- you need shareable, self-contained interactive documents as a single HTML file
- you want a small, approachable scripting language for creative projects
- you enjoy retro/fantasy-console aesthetics like ditherpunk pixel art

## When to avoid
- you need production-grade app development with modern UI frameworks
- you require high-performance multimedia or 3D graphics
- you need deep OS integration or native platform APIs
- you want a large ecosystem of libraries and package management
