That points at glyph bitmap bearing/subpixel placement/mask coverage or broader font raster fidelity rather than a missing inline centering hook.\n\nRelevant artifacts from the clean run:\n- crates/e2e/artifacts/real-web/opera.com/desktop.png\n- crates/e2e/artifacts/real-web/opera.com/desktop.png.diff.png\n- crates/e2e/artifacts/real-web/opera.com/mobile.png\n- crates/e2e/artifacts/real-web/opera.com/mobile.png.diff.png\n\nAcceptance:\n- Identify and implement the glyph positioning/rasterization fidelity gap with focused text/render tests.\n- Improve the Opera desktop and mobile differing-pixel counts materially without weakening the committed Chromium screenshot thresholds.\n- Keep crates/e2e/scenarios/real-web/opera.com.we xfailed until both Chromium assertions pass for isu issue 281.",
