+/* A copy button with a WORDED face is a chip, not an icon. The rule above is

+   label: the text wraps inside 42px into a one-word-per-line column and
+   spills out of its own box (observed on the health board's "clear them all"
+   line). Size to the label instead, and hold it on one line the way `.pill`
+   does — a chip that will not fit is elided, never allowed to push the page
+   sideways. `vertical-align:bottom` because `overflow:hidden` moves an
+   inline-block's baseline to its bottom edge. */
