// Composite-plugin "widget" surface: the DankBar pill. Reads connection/
// unread state the daemon surface (ChatDaemon.qml) publishes via
// PluginService global vars - see PLUGINS/README.md's "Plugin Global
// Variables" section for why this indirection exists (daemon and widget
// are separate object instances with no direct reference to each other).
//
// Clicking the pill bumps a "toggleNonce" global var the daemon watches,
// rather than PluginService.togglePlugin(pluginId) - that generic lookup
// didn't reliably find this composite plugin's daemon instance when
// tested against this DMS version. See ChatDaemon.qml for the other end.
