Code blocks move their buttons upstairs
Every code block now wears a slim title bar. Language sits on the left, wrap and copy sit on the right, and nothing sits on top of your code. In the photo viewer, a sideways swipe scrolls the code instead of flipping the picture.
Open a commit with a shell block and the floating badge is gone. A bar sits above the code now, language name on the left, two small buttons on the right. Scroll a long line all the way over and the last character is still there, not buried under a label. Click wrap and the line folds into the panel instead of running off the edge.
Credit goes to xHeaven, who lifted the controls off the code. The bar stands 32 pixels tall, the language name is set at 11 pixels, and each button is a 24-pixel square that stays visible instead of fading in when your pointer arrives. Copy flips to a checkmark for two seconds, then back. Wrap is a switch on each block, off by default. Down in the photo viewer's commit panel, the panel now grabs wheel events before the lightbox can, so a sideways trackpad swipe scrolls the code block instead of flipping to the next photo, while a pinch still refuses to zoom the page.
One catch. Every block gets that bar, one-liners included, so a single short line of code now sits under 32 pixels of header as tall as the buttons in it. Static excerpts in feeds show the language name alone, with no wrap and no copy.
