VDB_PALDUMP=<prefix> writes each completed 768-byte palette load to
<prefix>N.rgb (256 RGB entries per VDB display group). render_vdb_palettes.py
renders each as a 16x16 swatch grid + linear ramp.
First capture: pal1 (aux1) is a structured red/green/olive/black color map
(2-bit R x 2-bit G) -- likely the color display's status coloring; pal0
(secondary, dynamic ~29 reloads) and pal2 (aux2) are grayscale, sampled black
mid-animation. Palettes are the per-display color maps the VDB applies when
splitting the framebuffer to the six monitors.
