Modules and imports
===================

Workbench ships ``miskeyed.ui``, ``miskeyed.time``,
``miskeyed.viewport_camera``, ``miskeyed.render_toy``, and
``miskeyed.shader_toy``. Import only contracts a program uses::

   import miskeyed.ui;
   import miskeyed.time;

The built-ins have two categories:

**Host contracts**
   ``miskeyed.time``, ``miskeyed.viewport_camera``, ``miskeyed.render_toy``, and
   ``miskeyed.shader_toy`` describe values or resources supplied at Workbench's
   workspace, session, or render-surface edges.

**Library/language support**
   ``miskeyed.ui`` declares reflection metadata attributes and needs no runtime host
   state.

Slang owns import semantics and program composition. Workbench exposes packaged
sources through ``ISlangFileSystem`` and supplies project search paths. It watches
resolved project files; semantic catalog metadata exists only for packaging and the
Host / Slang Inspector. It is neither a parallel resolver nor a service locator.

The Inspector compares this catalog with dependencies actually loaded by Slang, so
**Available** and **Imported** remain distinct. See
:doc:`../concepts/host_features` for the complete mental model.
