Client Application & User-Space Architecture
From a desktop application, client performance, and user-space engineering perspective: - **Local-First Computation:** Workloads prioritize client-side execution, eliminating mandatory surveillance telemetry. - **Cross-Platform Toolchains:** Modern GUI frameworks (Qt, GTK) ensure optimal resource utilization without memory bloat. - **Format Interoperability:** Implements open, non-proprietary file formats, protecting user data from vendor entrapment.
