v0.1.1516 Jul 2026·Rendering, JavaScript & JIT, DevTools

Real sites render right

A 26-site sweep drove a compat sprint: modern app sites now render styled (script-injected CSS finally applies), progressive-enhancement layouts un-break (news card grids, footers), code blocks keep their formatting on a large encyclopedia and a Q&A site, logos paint their real colors, photos load on major news sites, and one broken script no longer takes the whole page down.

What changed 7 changes

JavaScript & JIT	Script-injected styles apply: sites styled by their JavaScript (large social sites and every styled-components/emotion app) render designed, not bare.
Rendering	@supports CSS now evaluates -> the modern grid layouts sites reserve for real browsers finally engage (news-site card grids, footers, headers stop overlapping).
Rendering	Code blocks keep their line breaks and indentation on a large encyclopedia, a Q&A site, and docs sites.
Rendering	SVG logos paint their real colors instead of black silhouettes, and CSS sprite icons (old.reddit vote arrows) appear.
Rendering	Photos load on news-site CDNs: honest image negotiation means the server sends formats we decode.
DevTools	One broken script no longer kills the page: each script runs isolated, errors go to the console, the rest boots.
JavaScript & JIT	A dozen JavaScript compat fixes that whole bundles were dying on: trailing commas, static blocks, dynamic import(), computed accessors, exponent-literal member calls, and more.
