Cockpit buttons on the split displays, lamp-lit and clickable

Each MFDSplitView window now carries its display's physical button bank,
placed as in the pod (addresses per vRIO CockpitLayout): a 4x2 red
cluster around each MFD glass (anchors 0x2F/0x27/0x37 upper, 0x0F/0x07
lower, addresses descending row-major) and 6 amber buttons down each
side of the map - Secondary 0x10-0x15 left, Screen 0x18-0x1D right; the
remaining column addresses are Tesla relays, per the pod wiring, so they
get no buttons.

Buttons light from the lamp state the game commands: PadRIO grows a
static active-instance hook (SetScreenButton/GetLampState); mouse
press/release feeds PadRIO's desired-state sampling alongside pad and
keyboard, and paint decodes the lamp byte (state1/state2 brightness,
solid/slow/med/fast flash animated by tick). With real serial hardware
(no PadRIO) the buttons draw dark and inert.

Verified: map flank buttons light per the game's preset lamps, aligned
with the labels the glass draws at its edges; MFD clusters render 4+4.
Roadmap: queued the vRIO Dynamic Lighting RGB-keyboard lamp mirror as a
polish-pass item. dist repacked.

-  pilot keypad (numpad → KeyEvent); Steam Input once C starts.
+- ✅ **Cockpit buttons on the displays** (2026-07-12): each split window
+  carries its physical button bank — 4+4 red buttons per MFD, 6 amber per
+  map side (Secondary/Screen columns; addresses per vRIO `CockpitLayout`,
+  placement per the pod). Mouse presses inject into `PadRIO`; the game's
+  lamp commands light them (verified: PRESET lamps lit on the map flank,
+  aligned with the glass's own edge labels).
+- Next in A: port the full vRIO bindings-file model (deflect/rate/deadzone

+  Steam Input once C starts.
+- Polish pass (queued): **vRIO's Dynamic Lighting RGB-keyboard mirror** —
+  lamp states glow on the physical keyboard's keys (per-key or zone-lit),
+  blinking with the flash modes. Needs package identity for background
+  light control (vRIO's `pkg\Register-vRIO.ps1` pattern; see the vRIO
+  README for the Settings → Dynamic Lighting steps).
 - vRIO itself stays useful as a dev harness against unmodified builds.
