Minor Changes
#11562b39aef - Add @tanstack/marko-virtual — a headless virtualisation adapter for Marko 6 using the runtime-tags API. Provides <virtualizer> and <window-virtualizer> tags covering fixed, variable, dynamic, grid, smooth-scroll, infinite-scroll, and window virtualisation patterns.

Patch Changes
#1206767ead4 - Cut per-scroll-frame allocations on the default lanes === 1 path. Range computation previously allocated an options object and two closures on every scroll event; it now does the same work allocation-free, reducing GC pressure during continuous scroll.
#1212bc8643b - Don't latch a scroll direction from the read-back of the virtualizer's own adjustment write
applyScrollAdjustment folds the pending adjustment into scrollOffset eagerly, so the browser's scroll event for that write arrives at exactly the held offset. The scroll-direction computation treated that equality as 'backward', which made the default shouldAdjustScrollPositionOnItemSizeChange skip above-viewport re-measure compensation for the rest of the isScrollingResetDelay window — so during multi-frame reflows (e.g. a side pane's width animation re-wrapping rows while scrolled up) most frames went uncompensated and the viewport drifted. An event at the held offset carries no direction information, so the direction now stays unchanged in that case; real gestures always move the offset and still latch normally.
