Props

Prop	Type	Default	Does
`code`	`string`	-	The source. One trailing newline is dropped, so the copy is exactly what is shown.
`language?`	`string`	-	Fence language. Aliases like `bash` and `js` resolve; unknown falls back to plaintext.
`copy?`	`boolean`	`true`	The copy button is the default; a caller showing a fragment can decline it.
`file?`	`string`	-	Filename from the fence's `file="..."` metadata, shown above the code.

Notes

copy and file both being unset is the only case that skips the code-shell wrapper and its tools row entirely - set either one and you get the wrapper, the language chip, and whichever of the two you asked for.

language never throws. An alias resolves through resolveLanguage (bash, js, jsx and a few others); anything else that is not a registered grammar falls back to plaintext, rendered but unstyled, rather than failing the build or the render.
