/* ============================================================================
   PictU — composite preview (editor + delivery)
   ----------------------------------------------------------------------------
   Both previews render the TRUE composite: the same JPEG every delivery path
   consumes, produced by compose.ts. main.ts sets `aspect-ratio` on
   .final-layout-container from the layout's real composite dimensions, so a
   3-wide strip is not forced square and a tall column is not cropped.

   The loose per-photo grid below is retained only as the fallback when
   composition fails, where main.ts sets `grid-template-columns: repeat(<perRow>,
   1fr)` instead of the aspect ratio.
