A console tool for validating the hardware replica against vPLASMA and the
real panel by feeding all three identical byte streams.
- synth — build a repeatable command stream (selftest/demo/banner/charset).
- render — feed a stream through the vPLASMA engine and save the resulting
128x32 frame as a PNG: the pixel-exact golden image.
- replay — send a stream to any target port: the real panel (RS-232, self-
pacing), the Matrix Portal replica (USB-CDC), or a virtual port
(--paced).
- capture — log live traffic to a file, with --tee to forward it on to the
real display so capture is non-intrusive.
Reuses VPlasma.Core (same parser/fonts as the emulator and the ported
firmware). The replica README documents the differential-test workflow.
