New post cascaded-noise-figure (scheduled 2026-04-29) with four
interactive scenes on noise floor, single-stage NF, the Friis
formula as a block builder, and LNA placement.
Upgrade the three static TCP scenes (data, sliding window, UDP)
to animated packet flow using a shared drawPartialPacket primitive.
Expand IDEAS.md with roughly thirty more post concepts across
electronics, networking, ham radio, microwave, and longer arcs.
Add outbound links to relevant first-mentions across posts:
Fresnel zone, effective Earth radius, atmospheric duct, HRRR,
BJT, common-emitter, TCP/UDP RFCs, slow start, QUIC, Friis,
noise figure, Boltzmann constant. Scrub Unicode arrows and
multiplication symbols out of prose and scene labels.
