OptionalclassClass for the layer's boundary div (devtools identification).
OptionaloffsetGap (px) between the cell and the card.
OptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalonOptionalplacementWhere the card attaches.
OptionalpreviewLooks up a preview of the linked page to show under the actions. Off by default: it is a request to a third party per hovered web link. linkPreviewMicrolink (the page's social card) and linkPreviewMShots (a screenshot) are two free ones; results are kept per address for the session.
OptionalrenderThe card.
OptionalstyleStyle for the layer's boundary div — e.g. display: 'none' or opacity to hide or fade a layer.
The boundary's own placement (position, inset, pointer-events: none) comes from the grid;
overriding it here breaks the layer's containment.
OptionalzExplicit stacking override, read by normalizeLayers off the grid-child element to sort the
layer list (higher sorts later = on top; omitted ⇒ declaration order). It is honored ONLY at the
grid-children level — the layer's actual dispatch slot always comes from the resulting order
index (via LayerOrderContext), never from this raw number, so paint order and event
order can never disagree.
Props for HyperlinkLayer.
