Layout is essentially complete, and modern visual styling arrives

This release finishes the layout engine and makes modern visual design render faithfully. On layout, every major piece a real site needs is now in and checked element by element against the reference browser across a suite that grew to 171 cases and passes in full: exact table borders, CSS subgrid, vertical writing modes for languages like Japanese and Chinese, and multi-column text that flows line by line into balanced columns. Just as important, the engine now proves things about its own layout that the reference browser does not: vertical text is built as a mirror of horizontal text so the two can never silently disagree, columns divide their space with no hairline gap where the reference browser leaves one, and deeply nested percentage widths add up exactly instead of drifting. On the visual side, the flashy parts of the modern web now work: gradient-filled headings, frosted-glass panels, the full set of blend modes, striped and repeating gradients, and circular avatars with a gradient and a ring - all verified against the reference browser on real components, where a sample profile card and settings form now render pixel-close. Three-dimensional card tilts and a handful of exotic effects are the remaining visual gap.

What changed 4 changes

Web APIs & DOM	Layout is essentially complete: an expanded 171-case suite matches the reference browser on every case, adding exact border-collapse geometry, CSS subgrid, vertical writing modes, and multi-column inline line-by-line fragmentation on top of the block, flex, grid and table box models.
Rendering	The layout engine now ships machine-checked guarantees the reference browser does not: vertical-lr is provably the exact mirror of vertical-rl, grid and flex tracks tile with no sub-pixel seam where the reference browser leaves a hairline gap, and nested percentage widths carry no cumulative rounding drift.
Rendering	Modern visual styling landed: gradient text, frosted-glass backdrop-filter, all eleven blend modes plus background blending, repeating linear, radial and conic gradients, and a fix so a gradient circular avatar with a border renders as a real circle, not a squircle.
Memory & reading	A selector-matching cache that leaked between pages could return different results on different loads; it is now cleared per document, so rendering is deterministic.
