# Optional UI dep: only pulled in when --features ui is set.
# Both `glow` (OpenGL 2+) and `wgpu` (DX12/Vulkan/Metal) are compiled in;
# the binary picks one at startup — glow by default for compat with the
# egui look-and-feel we've been shipping, but falls back to wgpu when
# `MHRV_RENDERER=wgpu` is set. Issue #28: users on older Windows
# hardware / RDP / VMs without OpenGL 2.0 crash with
# `egui_glow requires opengl 2.0+` — the wgpu backend uses DX12/Vulkan
# instead and covers those boxes.

# Unix-only deps. Must come after `[dependencies]` because starting a new
# table here otherwise ends the main one — anything below it (incl. eframe)
# would end up scoped to cfg(unix) and disappear on Windows builds.
# libc is referenced for the RLIMIT_NOFILE bump (issue #8 — OpenWRT routers
# ship a very low fd limit that fills up fast under browser load). Already
# pulled in transitively via tokio, so zero new weight.

# tun2proxy is the TUN <-> SOCKS5 bridge — it reads raw IP packets from the
# fd VpnService hands us, runs a userspace TCP/IP stack (smoltcp under the
# hood), and funnels every TCP/UDP flow through our local SOCKS5. Without
# this, VpnService establishes a TUN device nothing reads from and all
# traffic black-holes (symptom: Chrome shows DNS_PROBE_STARTED).
