/**
 * AudioWorklet processor that ingests mono Float32 audio at the AudioContext's
 * native sample rate, resamples to `targetRate` (linear interpolation, stateful
 * across `process()` calls), packs to little-endian Int16 PCM, and posts
 * fixed-size chunks via `port.postMessage` with a running `samplesSent` counter.
 *
 * `samplesSent` is in **target-rate samples**, so the main thread can derive a
 * stream-relative timestamp = `samplesSent / targetRate * 1000` (ms) — the same
 * frame AAI uses for `StreamingWord.start` / `.end`.
 *
 * Defined as a string so it can be registered via a Blob URL — the SDK ships as
 * a single ESM file, so a separate `.js` worklet asset isn't viable.
