The re-architecture split the Linux client into two binaries (shell + Vulkan
session streamer) and added the pf-ffvk crate, whose build.rs runs bindgen over
FFmpeg's libavutil/hwcontext_vulkan.h (#include <vulkan/vulkan.h>). Two release
regressions fell out of that on the desktop-package legs:
1. Missing build dep. The Arch build (archlinux:base-devel + its own pacman list)
fatal-errored at `vulkan/vulkan.h file not found`. Add the Vulkan dev headers
wherever the client compiles from a self-managed dep set: arch (PKGBUILD
makedepends + arch.yml), rpm (spec BuildRequires + rpm.yml + fedora image),
deb.yml (belt-and-suspenders; the rust-ci image already bakes libvulkan-dev),
and the screenshots job. The flatpak builds offline against the GNOME SDK, so
install Vulkan-Headers into /app as a pinned module and point pf-ffvk's bindgen
at it via PF_FFVK_VULKAN_INCLUDE.
2. Only the shell shipped. arch/deb/rpm built and installed just punktfunk-client;
the shell execs its sibling punktfunk-session for a connect, so desktop
streaming would break exactly as Decky's did. Build and install BOTH binaries
in all three, and declare the runtime Vulkan loader the session binary dlopens
(vulkan-icd-loader / vulkan-loader / libvulkan1 — not a DT_NEEDED, so
shlibdeps/auto-requires can't see it).

Host-free UI screenshots of the GTK4/libadwaita client under a virtual X display
(clients/linux/tools/screenshots.sh) — Xvfb + software GL (llvmpipe) + a root-window
grab, one app launch per scene. PUNKTFUNK_SHOT_SCENE routes build_ui to render one
mock-populated REAL view (hosts grid / settings dialog / TOFU + PIN dialogs) and
print PF_SHOT_READY once it has settled; the saved-hosts grid is driven by a seeded
client-known-hosts.json. NON_UNIQUE in shot mode so back-to-back launches don't
collide. The stream scene is deferred — its page needs a live NativeClient.
Gated to stable release tags in a standalone best-effort workflow that builds the
client in the rust-ci image and captures under Xvfb; PNGs upload as a 30-day
artifact, not committed.
