### System details

AMD Ryzen AI 7 350, AMD Radeon 860M Graphics (amdgpu / Krackan), [ASUS Laptop], Hyprland 0.56.2, quickshell 0.3.1-1, Omarchy 4.0.3-1, Kernel 7.2.3-arch1-3

### What's wrong?

#### Summary
When waking up / resuming from suspend (`s2idle` / sleep), the lock screen becomes unresponsive to keyboard input. The user cannot type their password or interact with the lock surface.

Switching to a TTY (via `Ctrl+Alt+F3`) and switching back to the graphical session (or logging into TTY) triggers a DRM/VT switch, which restores keyboard input focus and allows normal authentication/unlocking.

#### Steps to Reproduce
1. Suspend the machine (e.g. `systemctl suspend` or closing the laptop lid).
2. Wake the machine up.
3. Attempt to type the password into the lock screen prompt.
4. **Observed:** Keyboard input is completely unresponsive / keystrokes are not registered by the lock view.
5. **Workaround:** Switch to TTY (`Ctrl+Alt+F3`) and return to graphical session (TTY1/VT1); the lock screen immediately accepts input again.

#### Relevant Journal Logs (Sanitized)
Below is the resume sequence showing the USB reset, PAM wake relay, and Qt Wayland placeholder screen handling (`Not creating lock surface for screen QScreen(..., name="")`):

```

#### Investigation Hypotheses & Technical Context
1. **`ext-session-lock-v1` vs QtWayland Placeholder Output Desync:**
   - In `shell/plugins/lock/Service.qml`, guard logic (`hasRealScreen()`, `sessionLockStabilizeTimer`, `checkStrandedLock()`) handles session lock setup.
   - When returning from sleep, `qt.qpa.wayland` temporarily registers placeholder screens (`name=""`), causing `WlSessionLockSurface` to ignore them. When real outputs are restored, keyboard focus may fail to attach to the lock surface until a DRM/VT transition forces compositor surface and focus re-evaluation.
2. **PAM / Subprocess State on USB Reset:**
   - USB resets occurring at the exact resume moment could interact with the PAM fingerprint / password auth state in Quickshell, potentially causing input focus or handlers to stall until a display reset.
