/* The formatted output is the one thing on this page guaranteed to contain a
   very long line -- the Rust backend emits a whole file as one, which is the
   product working, not a rendering accident. Two rules keep that inside its
   box.

   `min-width: 0` on the panels: a grid item defaults to `min-width: auto`,
   meaning it refuses to shrink below its content, so the `overflow-x: auto`
   above never engaged and the panel widened the page instead. Scrolling the
   whole document sideways to read one pane is the symptom.

   Wrapping the output rather than scrolling it: minimized code carries no
   indentation to preserve, so there is nothing for a wrap to misalign, and a
   twenty-thousand-character line is not something to drag a scrollbar
   through. `anywhere` because the line may have no spaces at all. */
