Repo: gopher64-netplay (fork of https://github.com/gopher64/gopher64)
Context: Full scope doc at upstream analysis — see commit history. Netplay uses GGRS over WebRTC (matchbox_socket), reliable channel carries NetplayMessage { name, data } in 16KB chunks. Savestates serialize full Device via postcard + compress.

Goal: Expose the new features in the Slint UI with clear feedback.

Background:

Netplay UI: src/ui/netplay.rs (1047 lines) — create/join/wait windows, Slint callbacks via app.on_netplay_*
Input/keybind handling: src/ui/input.rs + config; onscreen messages via ui::video::onscreen_message

Acceptance:

Create-session window: "Resume Session…" button + file picker (.netplay-state), shown only when a state file exists
Wait window: "Save Session" button (host only; hidden/disabled for non-host), triggers #3 flow
In-game: save-session hotkey from #3 shows in the controls reference (if the UI has one)
Resync indicator: during resync, a small "Resyncing…" status in the corner (reuse onscreen_message OR a persistent badge — your call, keep it simple); replaced with "Resynced" on completion
Nice-to-have (only if cheap): show last-saved frame/time in the resume picker
Tests: UI wiring compiles; callbacks fire the right netplay functions (unit or manual — manual acceptable, note it)

Verification: cargo build clean; manual smoke: create session→save→quit→resume flow on 2 machines or 2 windows.
