//! Compositor-independent producer modules for the isolated desktop.
//!
//! These modules were extracted from the former `veston` and `vvsway` producers after being
//! proven byte-identical (or near-identical, differing only in product branding); the branding
//! differences are parameterized through [`ProductIdentity`] instead of duplicated strings. The
//! per-compositor backends keep their capture, input injection, compositor supervision, doctor,
//! and native build logic; this module holds exactly what they share.
