Crash: portable QIO dashboard "Computer" tab (flash drive)

Symptom: Opening portable QIO dashboard with flash drive installed crashes client while rendering screen.

NPE: hand is null
  RequestTerminalStatusC2S.portable(RequestTerminalStatusC2S.java:35)
  DashboardGuiHooks.requestStatus / onScreenRender
Screen: mekanism.client.gui.qio.GuiPortableQIODashboard

Cause: PortableQIODashboardContainer#getHand() can be null; we passed it straight into hand.ordinal().

Fix: Never return null from resolvePortableHand (infer main/offhand from stack, else MAIN_HAND). Null-safe portable() packet factories.

Blueprint layouts vs Mekanism validators (wiki + source)

Turbine (primary — was building garbage)

• Full solid floor + ceiling (no air holes on shell faces).
• Frame edges = casing only (glass on edges was invalid).
• Lower wall faces = structural glass; upper walls + ceiling = vents.
• Rotor shaft center; rotational complex; full disperser plane; coils scaled to blades.
• Condensers only above complex (not walls/ceiling).
• Odd square base 5–17; shaft height clamped to validator/wiki limits.
• Turbine blades (items, 2/rotor) auto-installed via mekacc.installTurbineBlade + builder mode=install_blade.

TEP

• Removed resistive heaters from the shell (they are external, next to a valve).
• Top corners left empty (validator IGNORED); top edges only.

SPS

• Frame cells = casing; face cells default to structural glass (saves SPS casing).

Fission / boiler

• Explicit FRAME vs SIDE match count (same rule as CuboidStructureValidator).
• Dimension clamps to wiki mins/maxes.

Builder

• Sort: same-cell install_blade runs after the block place.
• Port-mode apply skips install markers.
