+/**
+ * Approvals Inbox — the Approve / Reject column is pinned right and a long
+ * record title truncates (objectui#12816).
+ *
+ * Measured at 1024 px (HotCRM, three account approvals titled like
+ * "ACC-000011 - Contoso Pharmaceuticals and Life Sciences Group"): the table
+ * was 1074 px wide in a 718 px box. The titles are `nowrap`, and an
+ * auto-layout table sizes a column by its content's minimum width, so the
+ * Record column took 473 px and pushed the inline Approve / Reject column
+ * past the card's right edge.
+ *
+ * - The Record cells are `max-w-0`: the title no longer sizes its column, so
+ *   it truncates, its full text in `title`. The header keeps a floor.
+ * - The Approve / Reject cells are pinned right in the header and every row,
+ *   with the shared seam shadow (`PINNED_RIGHT_SEAM_SHADOW_CLASSES`), inside
+ *   the overflow box's `seam="pinned"` mode.
+ *
+ * jsdom lays nothing out, so the 718 px box is stubbed geometry and these pins
+ * read the classes that do the layout; the real-browser readings are on the
+ * pull request.
