   Spectacles 522 Portable Design · ptpavlotkachenko

   Design rules for building Spectacles lenses in Lens Studio 5.22 (CLAD/MCP workflow) so they downgrade to LS 5.15.4 for device testing in under an hour. Load when STARTING or architecting a new 5.22 Spectacles project that will later be tested on Spectacles (2024), when the user says "we will downgrade to 5.15" / "5.15-portable" / "we will test on device later", or before adding any shader/material/package to a 5.22 project that must survive the downgrade. Distilled from two full real-project migrations.
