/* The attachment look agreed with Felix on 4 Nov 2026 (2:15 PM SGT).
   Pictures: small same-height thumbnails that wrap, sit to the right, above the message. Everything else: one compact chip.
   Annotations: a small chip with a pen and a count; hovering it shows each selected text and comment with edit and delete.
   The message box and the sent message use the same rules. Phone sizes are the :root values in the media block. */
