### R15 — HTML guest focus before overlay control focus; x no-op and hover · guest 1000×700 · dark

Linux x86_64 (fs-06), real Electron 44.9.3 / Chromium 152.0.7977.167 under headless-desktop/Xvfb; no device emulation; full app 1256×780, guest 1000×700 CSS px, DPR 1, zoom 100%, font scaling 100%, dark theme. The 1256×860 recordings add an 80px narration band below the complete app surface.
