Kithara engine, SDK, and integration feedback

[gerasim13]

Kithara's public Strategy,
Roadmap, and
Development Project describe
the current engine and platform direction.

Use this discussion for experience reports and proposals concerning:

• the public Rust, Swift, Kotlin, or browser APIs;
• iOS and Android embedding and lifecycle behavior;
• remote streaming, cache, DRM, ABR, and recovery;
• musical-analysis import, synchronization, transition planning, and events;
• performance, latency, memory, battery, thermal behavior, and platform parity;
• extension points and non-DJ integration scenarios.

Please describe the host platform, intended behavior, observable limitation,
and the smallest public contract that would address it. Reproducible defects
should be reported separately as focused Issues.

Accepted changes are reflected in the Development Project or Wiki and linked
back here. This discussion preserves integration feedback; it is not a second
roadmap.
