The Deck's built-in controller can never leave Steam Input ("Steam Controller"
is always-required in the shortcut's matrix; Disable Steam Input only affects
other controller brands), so the raw 28DE:1205 device is the only path to the
trackpads/paddles/gyro. Steam hides it from SDL by launching shortcuts with
SDL_GAMECONTROLLER_IGNORE_DEVICES naming every physical pad it virtualized —
clear it (and _EXCEPT) at startup while single-threaded, logging what Steam set
as field evidence. The post-attach warning now states the real condition (raw
pad never enumerated; sticks + buttons still work) instead of advising a
Steam Input toggle that doesn't exist for the built-in controller.

Video (Deck): the VAAPI zero-copy path renders corrupt/gray/washed-out on the
Deck — root-caused to Mesa >= 25.1 exporting radeonsi VCN decode surfaces TILED
(the Flatpak runtime's Mesa 26 drives both the decoder and GTK's GL, and GTK's
tiled-NV12 dmabuf import mishandles it; desktop Tier-1 validations ran distro
Mesa with linear export). `auto` now resolves to software on a Deck (clean,
correct-colour, easily handles 1280x800 HEVC); PUNKTFUNK_DECODER=vaapi still
forces the hw path, with the descriptor modifier dump + GSK_RENDERER as the
bisect levers. Also reserve extra_hw_frames=4 on the VAAPI decoder: the
presenter pins mapped surfaces past receive_frame, and the fixed pool recycling
a surface the renderer still samples is intermittent block corruption anywhere.
Input (Deck): with Steam Input ON for Punktfunk, SDL sees only Steam's virtual
X360 pad — the right trackpad arrives as a plain right stick and the left
trackpad/paddles/gyro not at all, silently. The client now checks once the
post-attach enumeration settles and raises a toast + warn naming the fix
(disable Steam Input for the shortcut). The host logs a one-shot warning when
InputPlumber is running (Bazzite default) since it can grab the virtual Deck
pad and re-emit it under a different identity.

A controller-driven, chrome-less library launcher for the Steam Deck flow
(the Decky plugin's "Open library on screen" + pinned games, 3122506):
`--browse host[:port]` opens a paired host's game library as a coverflow
over a drifting aurora — A streams the focused title (the id rides the
Hello), session end returns to the launcher, B quits back to Gaming Mode.
`--connect` gains `--launch <id>` for direct-to-game starts; `--mgmt`
overrides the library port. Scope is deliberately library-only: host
selection/settings stay in the touch UI, pairing stays in the plugin (no
dialog can map under gamescope — every state renders in-page).
- gamepad.rs menu mode: the worker holds the active pad open while idle
(WITHOUT the Valve HIDAPI drivers — Deck lizard mode survives) and
translates it through a pure MenuNav state machine: edge-triggered
buttons, held-state snapshot on entry/detach (the escape chord that ends
a stream can't ghost-fire in the menu), 380/160 ms stick/dpad repeat,
menu rumble ticks. Keyboard fallback (arrows/Enter/Esc) drives the same
handler — fully usable with no pad, no host (PUNKTFUNK_FAKE_LIBRARY).
- Coverflow: ±38° corridor-facing tilt under per-card perspective
(gsk rotate_3d), dense overlapping side shelves with paint-order
restacking (gtk::Fixed draws in child order), opaque card faces + a
darkening veil for the recede (translucency would bleed the stack
through). The strip lives in an External-policy ScrolledWindow because
a bare gtk::Fixed measures its TRANSFORMED children and inflates the
page min-width past the window.
- Spring-driven motion: semi-implicit Euler in ≤8 ms substeps (a raw
50 ms frame leaves the stiff recoil spring ringing at ω·dt ≈ 1.2 —
regression-tested), ζ≈0.85 cursor chase + ζ≈0.55 boundary wobble;
velocity carries across retargets so held-repeat scrolling glides.
- Shot scene `gamepad-library` (GTK animations force-disabled in shot mode
— nav transitions froze mid-slide in headless captures); shared poster
fetch extracted to library::spawn_art_fetch.
Verified here: 21 unit tests (MenuNav, cursor stepping, spring
convergence/stability), clippy -D warnings clean, screenshot scene
pixel-checked, --browse smoke runs (fake-library + unpaired) on the
headless session. On-Deck validation pending (virtual-pad input, lizard
mode, rumble via Steam Input, full Decky→browse→stream→launcher loop).

- "Automatic" gamepad type resolves to the virtual Steam Deck pad on Deck
hardware (env SteamDeck / DMI Jupiter|Galileo): the built-in 28DE:1205
identity is invisible at Hello time — the Valve HIDAPI drivers run
in-session only and Steam Input shadows the pad with its virtual X360 —
so auto always fell through to Xbox 360. "steamdeck" is now also
selectable in Settings.
- Chrome-less launches flatten the window CSS (border-radius/box-shadow)
and fullscreen at startup: gamescope never ACKs the xdg fullscreen
state, so adwaita kept the floating-CSD rounded corners + shadow
visible over the stream.
- Gaming-Mode --connect launches quit on session end, so Steam ends the
"game" and the Deck returns to Gaming Mode — previously the app popped
to its own hosts page, stranding the user fullscreen and making the
escape chord read as broken.
- The capture hint is controller-aware; the chromeless hint teaches the
hold-chord ("hold L1+R1+Start+Select to leave") and a quick chord press
re-flashes it.
- Colour bisect for the reported off-colours on the VAAPI dmabuf path:
graphics offload defaults OFF under gamescope (a subsurface hands the
NV12 CSC to the compositor), PUNKTFUNK_OFFLOAD=1|0 overrides, and each
colour-signaling change logs whether GDK accepted the BT.709-narrow
color state (fallback = GDK's BT.601 dmabuf default).

Root-caused fixes from on-Deck testing (owner + first external tester):
- System input broke while the app was merely OPEN: SDL's Steam Deck HIDAPI
driver clears the built-in controller's "lizard mode" (trackpad-mouse,
clicky pads) at device ENUMERATION and keeps feeding the firmware watchdog
(SDL_hidapi_steamdeck.c InitDevice/UpdateDevice) — and we enabled that
driver at startup and held every pad open app-lifetime. The Valve HIDAPI
hints are now enabled only while a session is attached, and only the active
pad is opened (Settings enumerates via SDL's ID-based metadata getters, no
open). Close/detach hands the hardware back; the watchdog restores lizard
mode within seconds. This also unblocks click-to-capture on the Deck (the
dead trackpad made "input not passed through" a symptom, not a cause).
- Washed-out colors from a Windows host with an HDR desktop: the host ships
Main10 BT.2020 PQ IN-BAND (correct VUI) while the Welcome still says SDR;
this client rendered everything as BT.709 narrow. Colour signaling is now
read per-frame (video::ColorDesc from the AVFrame CICP fields) and drives
the GdkDmabufTexture color state, the software path's swscale matrix/range
plus a tagged MemoryTexture for PQ, and an "· HDR" HUD chip — GTK tone-maps
correctly on SDR displays, mid-session SDR↔HDR flips included. Regression-
tested against a checked-in Main10 PQ fixture (tests/pq-frame.h265).
- Streams start fullscreen by default (Settings toggle; F11 / the controller
chord lead out, and the pointer at the top edge reveals the header while
input isn't captured — a Deck desktop has no F11). Gaming-Mode launches
(--fullscreen / Deck env) build the stream page with NO header bar at all:
gamescope doesn't reliably ACK xdg_toplevel fullscreen, so anything keyed
on is_fullscreen() could leave the title bar drawn over the stream.
- Game Mode settings were uneditable: GTK popovers are xdg_popups, which
gamescope never maps for nested apps — every ComboRow dropdown flashed and
died. Under gamescope the preferences dialog now uses in-window selection
subpages (PreferencesDialog::push_subpage) via a ChoiceRow that stays a
stock ComboRow on desktops. Covered by an in-process GTK test
(choice_row_modes, #[ignore]d — needs a display).
- Forwarded-controller pin persists across restarts (Settings::forward_pad,
stable vid:pid:name key — SDL instance ids are per-run) and survives
disconnects; automatic selection skips Steam Input's sensor-less virtual
pad (28de:11ff) so gyro doesn't silently die on Bazzite/Deck.
- "Punktfunk" branding in the About dialog.

- library.rs + ui_library.rs: the host's unified game library over the
management API (the Apple LibraryClient/LibraryView ported) — mTLS with the
paired identity, host verified by its pinned cert fingerprint (ureq + rustls,
unified with the workspace rustls 0.23); posters load async with monogram
placeholders, and picking a title starts a session that asks the host to
launch it (the library id rides the Hello).
- app.rs (~800 lines lighter) splits into cli.rs (argv/headless
pairing/--connect/screenshot scenes), launch.rs (mode resolve + session
worker + event stream into the UI) and ui_trust.rs (TOFU / SPAKE2 PIN /
delegated-approval dialogs); ui_hosts/ui_stream reworked around the split.
