bzzz, Haptic + Audio Feedback Library

bzzz is a tiny tactile feedback library for the web. I built it as a craft project to explore the underused 'feel' layer of web UI. One API, two channels. The Vibration API for haptics on supported devices, WebAudio for synthesized click, tap, success, and error cues. Ships an ESM and CJS core plus a React adapter (useHaptics, <Haptic>). Most components stop at visual feedback. bzzz adds the millisecond a finger expects.
