/*
* Thunderbird user.js — non-private configuration tracked in dotfiles.
*
* Tight, curated set. Each pref changes a behaviour I actually want;
* defaults already-shipped by Mozilla/Arch are NOT restated.
*
* Inspired by (not copied from) HorlogeSkynet/thunderbird-user.js.
* Deployed by run_onchange_after_deploy-thunderbird.sh.tmpl.
* Accounts, passwords, mailboxes, calendar/contact data stay local.
