Raw HTML body (localization key or literal), split on newlines.
Machine-friendly id, unique within the tour.
OptionalrestrictedWhether the step is GM-only.
OptionalselectorCSS selector of the element to highlight; centered if omitted.
OptionalspotlightCSS selector of an element to spotlight (ring with the fade "hole") while the step's card stays centered and stable — unlike selector, which anchors the card to the target via Foundry's shared tooltip. Use this to point at an element that itself has hover-tooltips or re-renders (a sidebar tab, a directory button): the card can't be hijacked or lost because it isn't tooltip-anchored, yet the target is still clearly indicated. Ignored when selector is set.
Tooltip header (localization key or literal).
OptionaltooltipPreferred tooltip direction relative to the target.

TourStepdata fields SoHL reuses verbatim. Kept as a local interface (rather than importing Foundry types) so this module stays Foundry-free and passes the logic-layer purity harness.
