/* ====================================================================
   HD30 Canonical attachment component
   The single attachment layout used across messages, notes, tasks,
   description and compose forms (window.Attachments.render). A fixed-size
   file-icon tile that never resizes or reflows; hovering reveals a popout
   with the filename (+ size when known). Saved files download on click.
   A circular remove badge sits on the tile's top-right corner, revealed on
   hover and rendered only when the parent item is editable (canRemove).

   Loaded globally from _Layout so every page shares one definition.
