What

A new registry:ui item, code-block: text a member copies and runs or pastes, such as a command, a request or a config file.

• A 2.5rem bar with an optional title and a copy button; the icon turns into a check for 1.5 seconds after copying.
• The text keeps its own line breaks and scrolls sideways, so a long line never breaks inside a word.
• Same edge and corners as terminal and browser, but in the page's colors in both themes.
• DESIGN.md says when to use it; README and the docs site list it.

Why

The portal's developer page shows its OAuth endpoints as lines of font-mono prose that wrap in the middle of words. terminal draws another program's window, and markdown's code has no copy button, so neither fits.

Verified

On the sandbox, against the static build, with Playwright: light and dark at 900 wide and dark at 390 wide. In each, 6 lines stay 6 rows, the page does not scroll sideways (the block does, on the phone), the clipboard holds the exact text, the button's name goes 複製, 已複製, 複製, and it works from the keyboard. 22 of 22 checks pass.

lint, prettier --check, tokens:check, theme:check, tsc and build pass.
