## Evidence — Z: No setup environments Before [c6ca605630](https://git.cafe/pingdotgg/t3code/commit/c6ca6056309904f89b90b6055d797973be0a0939); after [21e22d030c](https://git.cafe/pingdotgg/t3code/commit/21e22d030ca430ef680082630274b3b1c073d35c). Web only. Headless Chrome 157.0.0.0 on Linux via agent-browser 0.41.2 and native CDP screenshots; no device emulation; DPR 1; default zoom; 16px root font, 100% scaling (W: 125%, 20px system-ui, resolving to Liberation Mono on this VM); reduced motion; frozen client clock 2026-11-09 09:40 UTC. Viewports are 1440×900 and 390×844 CSS px, each light/dark. Each environment JSON records the actual settings. Every still passed network-idle/fonts readiness and two pixel-identical frames 500ms apart. Diff0 marks every nonzero RGB-channel difference in full magenta; DiffT uses maximum channel difference >16/255. Absolute RGB×32 images are also linked. P/E use real isolated apps with three synthetic Pi sessions or empty isolated provider homes. L uses the real app and scanner with an explicitly instrumented transport gate: it delays the outgoing scan RPC until the scripted release; this makes the loader readable and does **not** measure scanner speed. M–W are explicitly labelled production-component harness captures with synthetic boundary values. No production data or session JSONL is uploaded. ### What else changed Context caveats: Escape remains open on both revisions; G keyboard-focus tooltip is unverified; W populated 390px/20px has existing horizontal overflow. See the index review notes. The loader, description and successful-empty copy change. Where shorter text wraps onto fewer lines, the dialog height and vertically centered content move; the modal backdrop/shadow moves with it. No other source changes are part of this PR. Any additional observed difference is recorded in the index review notes. ### 1440×900 · dark | Before | After | Diff0 | DiffT | |---|---|---|---| | ![before-Z-1440-dark.png](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/d34d9bd4927cc5ee/before-Z-1440-dark.png)
