"use strict";

// Ships the branded T3 mark to the Live Activity / widget extension.
//
// expo-widgets generates ExpoWidgetsTarget without a Resources build phase and
// has no asset support, so this plugin (a) writes an SVG template image set into
// the generated widget asset catalog and (b) wires that catalog into the widget
// target with an actool build phase.
//
// ORDERING: must be listed BEFORE "expo-widgets" in the plugins array. Expo
// chains same-type mods so the last-registered runs FIRST; registering this
// plugin earlier makes its mods run AFTER expo-widgets' mods. That matters
// twice: expo-widgets' dangerous mod rmSync's ios/ExpoWidgetsTarget/ (deleting
// any catalog written before it), and its xcodeproj mod is what creates the
// widget target. Listed after expo-widgets, both steps silently no-op on a
// fresh prebuild — which is how prod build 8 shipped without the logo.
