- grid, tables, `position` (relative/absolute/fixed/sticky), margin collapsing,

## Not supported yet (stated, not hidden)

+- `conic-gradient` is recognised but not painted. `filter` and `mask-image` are
+ modelled narrowly: a mask is a single `url()` stretched over the box. `scale`
+ and `skew` are not supported. SVG has no ``/``/``/
+ ``/embedded ``, and a per-page image budget caps very icon-heavy
+ pages.
+- `::before`/`::after` generated content is not synthesised, so some icon-font and
+ `visually-hidden` chrome renders as text where a browser shows an icon.
+- Rate-limited image hosts (Wikimedia) answer some requests with HTTP 429. The
+ engine retries them and the renders are identical, but each retry adds about two
+ seconds to that page.
- Large computed pages (pkg.go.dev, go.dev) render **slower** than Chrome — a perf
gap, not a fidelity one.
- This is **not** a standards-complete browser and is **not** claimed to match
