// Summary: M0 placeholder home screen showing the app name and version.
//
// HomeView: the M0 placeholder home screen. It draws the app name and version
// in the centre of the screen. Milestone M4 replaces it with the entry list.
//
// Performance note: everything that allocates (loading the name string,
// building the version text) happens once in initialize(), not in onUpdate().

import Toybox.Lang;

private var _version as String;
// Set after the first complete draw, so start-up diagnostics run once.
