Layered APIs (LAPIs) are a new standards effort for shipping high-level features, exposed to the web as JavaScript modules. Their specifications are required to be layered on top of existing lower-level platform features, and never use any "magic" that is inaccessible to JS developers. This feature covers the infrastructure for importing LAPIs, via std:x|y module specifiers in <script type=module> and JS import statements.
