This tool prefers undo to confirmation, deliberately — runUndoable says so in as many words — which makes the toast's Undo the safety net under the biggest things it does. It was not one. Every whole-step undo clears the per-action history on its way past, so the bar has no pill left and the toast's button is the only way back. Measured on a desktop it is the 67th of the page's 68 tab stops, and it is gone in eight seconds. And U — the key the sidebar legend advertises as taking back the last action — found nothing and did nothing: it only ever looked in the bar. So U looks at the toast first, by pressing the button that is on the screen rather than running a second copy of what it does, and only at a button that named the shortcut: "Turn off" on the wake lock and "Reload" on the other-tab warning are not things a stray keypress should reach. The eight seconds also ran whatever the dealer was doing. A cursor resting on the toast did not stop it; nor did tabbing onto the button. Measured before: focus the Undo, wait 8.6 seconds, and the toast is gone and focus has been handed to <body> — the offer withdrawn and the dealer's place in the page with it. Touching it or tabbing into it now stops the clock, and letting go starts it again with at least the time to act rather than whatever was left of the time to notice: let go at 7.9 seconds of 8 and 100ms is not an offer. Dismissing with focus inside puts focus back where the dealer had got to, which is read off where focus crossed into the toast rather than off where it was when the message arrived. And each toast carried its own role="status" inside #toastHost, which is already a live region in the markup. A region nested in a region, announced twice; the one in the markup is the one that works, because it is the one anything has been watching. 1342 tests pass, 18 of them new — and 8 of those fail against the old code. The sweep is clean across 428 audits; contrast unchanged. Co-Authored-By: Claude Opus 5 <[email protected]> Claude-Session: https://claude.ai/code/session_015bnp7xKUPFFSpwkYNFaPgb
