Goal

Give the watchapp real speed immediately, so it is genuinely useful before any Android work exists.

Acceptance criteria

PKJS navigator.geolocation.watchPosition() with enableHighAccuracy: true, maximumAge: 0
Error handler and timeout present on every geolocation call
Speed and position forwarded to the watch using the shared message keys
Distance and average accumulated on the JS side for now
Known limitations documented (background reliability, no BLE sensors)

Files

watchapp/src/pkjs/index.js

Notes

This is scaffolding, replaced by the companion app in Phase 2 and kept only behind a fallback flag.
