The cron has thrown on every run for ~24h (114 consecutive exceptions, none before that). The latest episode was published as a .wav, so PowerPress rendered a link-only player instead of an HTML5 one, and the `audio source` selector in getAudioUrl matched nothing. Reading the media URL out of theme output meant any rendering change could break the pipeline. The podcast feed carries the same URL in its <enclosure> tag, which is a stable contract, so getEnclosure replaces getHTML/getAudioUrl and src/audio.ts goes away along with the cheerio dependency. The feed also declares the file size, which fixes a second latent bug: sendTelegramAudio buffered the whole file via arrayBuffer(), so the current 104 MB episode would exhaust the 128 MB isolate long before the 50 MB guard fired. Files at or under 20 MB are now handed to Telegram as a URL and never pass through the worker; larger ones still buffer. The Blob content type is derived from the file extension rather than being hardcoded to audio/mpeg.
