//! Shared, UI-agnostic client plumbing, extracted verbatim from the GTK client
//! (design: punktfunk-planning `linux-client-rearchitecture.md`, Phase 0) so the desktop
//! shells and the Vulkan session binary build on one implementation — on Linux AND
//! Windows (the session binary runs on both; macOS stays `wol`-only, clients/apple is
//! the client there).
//!
//! Nothing here may depend on a UI toolkit: the presenter contract is `session`'s
//! channels (`SessionHandle`) and `video`'s `DecodedImage` (RGBA bytes, dmabuf fds +
//! plane layout, or a decoded VkImage) — how frames reach the screen is the consumer's
//! business.
//!
//! Audio is the one per-OS module swap: `audio.rs` (PipeWire) on Linux,
//! `audio_wasapi.rs` (WASAPI) on Windows — same public surface, picked here by `#[path]`
//! so `crate::audio` is the only name the session pump ever sees. `keymap` (evdev-keyed)
//! stays Linux: the session path uses pf-presenter's SDL-scancode table instead.

// Unsafe-proof program: every `unsafe {}` / `unsafe impl` in this crate carries a `// SAFETY:`
// proof of why it is sound. This crate held ~91 unsafe items with NO enforcement while every
// other subsystem crate denied it — the decoders' `unsafe impl Send`s had a one-line aside
// instead of an argument precisely because nothing required one.
