- diff — compare two frames/images/encodings (.bin ESC P / .png / .txt
bitmap=), each reduced to 128x32; reports differing dots and match %, writes
a red-on-mismatch image, exits 1 if they differ. Closes the differential-test
loop: diff a cropped panel/replica photo against the vPLASMA golden image.
- text / encode / decode — ported from TeslaSuite's three plasma tools (Plasma
Font Tool, Bitmap Decoder, Editor) via PlasmaBitmap.cs:
* text — render text in an auto-sized Windows font to a plasma bitmap.
* encode — an image → plasma bitmap.
* decode — the game's bitmap= hex encoding → a preview PNG.
Each bridges to an ESC P wire stream (and/or the bitmap= hex encoding), so
authored content replays straight to vPLASMA, the replica, or the real panel.
Verified: text "ALERT 12" → ESC P → vPLASMA renders it; the ESC P and hex
paths diff as byte-identical (504/504 lit, 100% match).

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.
