# R14 evidence

Before [5808469018](https://git.cafe/pingdotgg/t3code/commit/5808469018fb95676af148e7a7662c23665c67a3); after [1667f6fbf1](https://git.cafe/pingdotgg/t3code/commit/1667f6fbf15e0b2e5a8269ecdbdc00f793017bab).

### R14 — Element + region + stroke; erase to zero; B/C marquee · 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.

The tools create a selected Card A, an empty-space region and a retained stroke. Erasing all three hides the editor. A region drag over B/C selects those elements; erasing them also returns to zero targets.
