docs(pfi-gx10,nh3-pve): AC-restore patch validated; nh3-pve OOB held blind until next NH3 visit (NanoKVM → gx10, MS-01 → own vPro)

   Display = IGFX (or enable iGPU Multi-Monitor). Reaching the BIOS now needs a
   display on the RTX's mini-DP, for example the NanoKVM through a mini-DP→HDMI
   adapter. Verify with `lspci | grep 00:02.0` and `boot_vga` on `00:02.0`.
+- **OOB decision (Prime via Miranda, 2026-09-25): HOLD. nh3-pve stays console-blind
+  until the next NH3 site visit.** No BIOS change and no reboot until then. The
+  accepted risk: a boot without network means a site trip. **Target end state:**
+  the NanoKVM moves to pfi-gx10, and this MS-01 gets out-of-band access through its
+  own vPro/AMT (cable the I226-LM `enp88s0` and provision MEBx; see the AMT bullet
+  above).
+  ⚠ **Do the BIOS fix on that same visit.** AMT's KVM redirection captures only
+  the Intel iGPU's framebuffer, so with the iGPU hidden as it is now, AMT KVM would
+  be just as blind as the NanoKVM. Order: while the NanoKVM is still here (on the
+  RTX through an adapter), set Primary Display = IGFX, provision MEBx, confirm AMT
+  KVM shows the console, and only then move the NanoKVM to the gx10.
