Servo-replacement runtime for Tauri: wires html-cat, css-cat, dom-cat, layout-cat, paint-cat, net-cat, boa-cat, ecma-runtime-cat, and web-api-cat into a single rendering + scripting pipeline. v2.3.0 upgrades the zoom compositor from nearest-neighbour to bilinear sampling: each destination pixel weights four surrounding source pixels by `(1 - x_frac)`, `x_frac`, `(1 - y_frac)`, `y_frac`, smoothing edges at non-integer zoom factors. Crisp glyph re-rasterization at zoom waits on a layout-cat font-scale parameter (deferred). The Servo no-AI policy disqualifies upstream contribution; this is the AI-built parallel.
