Fig. 3 is now the 10 dB aggregate with the token-domain bars, the
non-MAML reference carries its figure label, the load-sweep script is
listed, and the probe reference value matches the reported runs.
Semantic Multiplexing Gain in Wireless Systems via Expanded Embeddings:
A BERT Case Study. Includes the shared library, all experiment scripts
(training with and without SNR-aware MAML, the token-domain comparison,
the K sweep, and DistilBERT), the replot script that regenerates every
figure from the stored results, the supplementary probe-versus-cosine
analysis, and the raw results behind every figure in the letter.
