eitri-bifrost

Reference and authoring guide for eitri-bifrost — Eitri's native bridge that exposes device capabilities (navigation, storage, HTTP, camera, code scanner, geolocation, biometrics, clipboard, share, haptic, notifications, file system, deeplinks, tracking, event bus, etc.) to Eitri-app JavaScript. ALWAYS invoke this skill whenever the user asks about Bifrost APIs, calls Eitri.<x> / imports from eitri-bifrost, asks "how do I navigate / store / take a photo / scan a QR code / track an event / open a deeplink / call an HTTP API in Eitri?", or whenever a question requires consulting the official Bifrost typedoc at https://cdn.83io.com.br/library/eitri-bifrost/doc/5.1.0/. Also use when reviewing Eitri code for Bifrost-correctness (no fetch/localStorage/navigator.* — use Bifrost equivalents; await async APIs; canIUse guards for capability gating; permission flow before sensor APIs).
