Log messages are lower-case event names with their details as key/value
attributes ("error" for errors), in place of formatted strings.
Loggable package take a WithLogger option as part of their "New*" call,
defaulting to slog.Default(). Each tags its lines with its `component`.
Some debug loggers print directly rather than using slog when in
terminal logging mode.
