api.py runs the camera producer in a background thread and serves the
latest entropy blob over HTTP. Endpoints: GET / (info), GET /healthz
(liveness, unauthenticated), GET /entropy (returns {hex, bits, ts}).
Auth is a single shared secret via X-API-Key header, controlled by the
ENTROPY_API_KEY env var; empty means no auth, so it is easy to start
open and lock down later. All config is via env vars for containers.
Dockerfile uses python:3.12-slim, installs OpenCV runtime libs, pins
deps from requirements.txt, exposes 8000, and has a healthcheck against
/healthz. Run with: docker build -t entropy-rng . && docker run -p 8000:8000 \
-e ENTROPY_CAMERA_URL=http://192.168.0.200/mjpg/video.mjpg entropy-rng
