`[skin_effect] remanence`

Old shell, new soul. A 1970s cassette deck retrofitted into a fully custom networked audio player. Yocto-based Linux for the audio brain, ESP32-C6 for the analog guts — potentiometers, needle VU meters, buttons and LEDs — and a discrete linear power supply keeping the noise floor honest. Because vintage hardware deserves better than a Raspberry Pi thrown inside a box.
