/* Orbit Axis :: Compatibility (Dev Update 1.11)
 *
 * WIDTH DISCIPLINE, stated first because it is what broke twice before.
 *
 * Dev Update 1.10 shipped a 375px layout that expanded to 522px on long
 * <select> option labels, and 1.10.1 pushed a page to 921px on a single
 * unbroken token. Both had the same cause: a grid child's default min-width is
 * `auto`, so it refuses to shrink below its content and silently widens its
 * parent instead.
 *
 * So: every grid child here declares `min-width: 0`, every track is
 * `minmax(0, 1fr)`, and any text that could arrive as one long token wraps with
 * `overflow-wrap: anywhere`. That is not defensive styling, it is the fix for a
 * bug this file would otherwise reintroduce.
