Summary
Works almost exclusively on font and text handling in WebCore — `@font-face` descriptor parsing and serialization, font-synthesis behavior for variable fonts, `FontCache` purging, and CoreText platform glue — with a secondary concentration in Platform. The pattern is CSS Fonts spec-conformance and font-object plumbing rather than security work, but the security fixes that do appear are both font-object lifetime bugs: retaining system fallback fonts used by the complex text path, and copying fonts when a display list crosses between `RemoteRenderingBackend`s. Systematic-variant candidate: font object ownership across the GPU-process IPC boundary and in the shaped-text/glyph-page caches, where the same retain-vs-reference mistake has now surfaced twice.
