HARP endpoint for micro-TCN, a lightweight temporal convolutional network
that emulates the Teletronix LA-2A optical compressor/limiter.

The model takes two conditioning parameters, mode (compress or limit) and peak
reduction, which map to the hardware controls of the original LA-2A.

This deployment uses the causal uTCN-300 variant (302 ms receptive field), with
the pretrained weights of the author mirrored on the Hub.

The input is mixed to mono and resampled to 44.1 kHz for the model. The result
keeps the length of the input, and is resampled back to its rate and copied
across its channels. The endpoint accepts clips from 0.5 to 30 seconds.
