 *
 * The auto margin lives HERE, on the group that is always present, rather than
 * as a .me-auto on the alternate button. Two reasons, both learned the hard way:
 *
 *   1. It survives the button being hidden. On create there is no alternate
 *      action, and this group must still sit at the end edge — which it does,
 *      because its own margin is what places it, not the presence of a sibling.
 *   2. margin-inline-start is a REAL logical property, resolved by the browser
 *      from `direction`. Bootstrap's .me-auto is a compiled utility that means
 *      margin-right in the LTR build and margin-left in the RTL one, so it
 *      depends on which of the two stylesheets the page happened to load. This
 *      does not: one rule, correct in both directions, no RTL counterpart.
 *
 * Verified flush at both edges in ltr/rtl x shown/hidden.

   On small screens the .source-count badge sat between the textarea

   the source-count + action buttons sit on a second row below it.

   MOBILE: Chat message bubble fix (iPhone)
   On narrow viewports the assistant message bubble was overflowing
   horizontally because:
     1. .message-content-wrapper is a flex child with no min-width:0,
        so long Arabic words / inline-flex .doc-reference pills forced
        the bubble wider than its 85% cap, pushing the right border
        off-screen and visually breaking the highlight.
     2. .doc-reference pills had nowrap children (.doc-ref-name with
        max-width:150px) making each pill an unbreakable ~250px block.
   Fix: allow shrinking, wrap long words, and let pills wrap their
   internal parts on small screens.
