/* Anchors the popup: relative positioning lives on the field itself (not a

   panel's `top: 100%` sits directly under the input with no gap, and its
   width matches the field exactly instead of a separate, wider minimum
   spilling into the Compose card next to it (WW-89 opus review — visual).
   This CSS was inert until the opus re-review (finding #1): the panel markup
   was a *sibling* of .picker-field in the HTML, so it anchored to the
   nearest positioned ancestor up the tree (#class-step) instead of this
   element. The panel is now nested inside .picker-field in index.html.
   The 20px margin-bottom that the generic `input` rule (below) puts on
   #picker-input is zeroed on .picker-input and moved here instead: as a
   margin on the field's own box it doesn't affect the field's content
   height (and therefore doesn't affect the panel's `top: 100%`), but still
   preserves the original spacing before the next element in the step. */
