"""Render a courtroom-sketch witness placard as the portrait placeholder.

    python3 scripts/make_portrait_placeholder.py   ->   assets/marcus_reid.png

app.py shows assets/marcus_reid.png if it exists, else an empty box. A real
AI portrait (HF ZeroGPU) can overwrite this file later; until then this gives the
demo an intentional, on-theme visual instead of a blank frame. Pure PIL — no GPU,
no network — and it matches the app's parchment palette.
