Zepp OS Watchface

Context: Watchface (a distinct appType, not a Mini Program app). API_LEVEL: 1.0+ (legacy hm* globals on 1.0; @zos/* on 2.0+). Prereq: project structure & app.json — see zepp-os-fundamentals. Widgets — see zepp-os-ui. Data — see zepp-os-sensors.

Overview

A watchface is not an app: appType is "watchface", there are no pages, and the entry is WatchFace({ … }) (one render surface, not Page/App navigation). Two ways to make one: the visual Watchface Maker (no code) or a coded project via Zeus CLI (this skill).
