// passed no emblem.

// AFTER - she already has a face, so there is no symbol to choose.
// Inlined as a data URL for two reasons: the deploy mechanism is
// text-only (no binary vendoring), and a launcher that 404s while
// the assistant is offline would be worse than no launcher.

// WHY A DEFAULT AND NOT A RULE
//
//   rule    : every future author must KNOW it and REMEMBER it at
//             the moment they pick an icon.
//             failure mode = omission  -> the most common thing
//                                         that happens
//
//   default : passing nothing yields the correct result.
//             failure mode = deliberate override -> rare, and
//                                                   visible in a diff
//
// The division of ownership, stated so it is not read as "the
// shared layer owns everything":
//
//   shared layer owns : what she LOOKS like (the mark, the launcher
//                       around it)
//   the app owns      : where the launcher SITS, how it is toned,
//                       and its own emblem for its own identity in
//                       a panel header
//   nobody may        : put a machine in her place
