OptionalgroupThe tab's group (data-group); defaults to the sheet's primary group.
OptionalsidebarA sidebar directory (data-tab) to activate before the step is shown —
e.g. "actors" so the Actors directory's Create Actor button is
rendered and visible for the step to highlight. Scene-setting only: it
merely opens the directory; the user still clicks the control (PRIME
DIRECTIVE — assist, don't play the game).
Optionaltabdata-tab id to switch to before the step's selector is resolved.
OptionaluuidUUID of the Actor/Item whose sheet to open and await before the step.
Scene-setting navigation a step performs before it is shown. Only navigation is ever automated — never the user's meaningful choices — per the PRIME DIRECTIVE (assist, don't play the game).
