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).
