/**
 * Runnable showcase for long inline-code coordinates inside table columns.
 *
 * <p>A composed cell holding a single long {@code inlineCode(...)} token — a
 * Maven coordinate, fully-qualified class name or URL — no longer overflows its
 * column. In a narrow <b>fixed</b> column the chip breaks <em>inside</em> the
 * cell, preferring its {@code . : / -} seams and char-splitting only as a last
 * resort, with the rounded fill intact on every fragment. In an <b>auto</b>
 * column the column grows to fit the coordinate on one line instead of
 * collapsing.</p>
