// ── The optional mods (PLAN.md §33, protocol 12) ──────────────────────────
//
// BetterChat titles, BetterChat group styles, the voice, and popups. Every test
// here is one of the ways the phase can look right and be wrong:
//
//   a title goes to nobody on a fresh wipe; ties follow the leaderboard; a mode keeps what it says
//   an operator's title cannot carry markup, and a title made only of markup is refused
//   a style is all twelve fields, in the spelling BetterChat's setter takes
//   a voice has no sender: no username, and no stray colon where one was
//   a style field carries what the site last pushed THERE, and landed only if the game took it
//   a withdrawn style is one `chat-group` retirement, never for `default`, and leaves the
//     ledger only once BetterChat has removed the group
//   titles skip a plugin older than protocol 12, and push again on a restart or a wipe
//   a popup refused for want of PopupNotifications is not retried
