/* ============================================================
   BANNER CROP GUIDE — STYLES
   
   KEY CONCEPT: The .banner__frame element contains both the
   image AND the guide overlays. It always maintains the image's
   native aspect ratio (8:3) and is scaled to "cover" the
   .banner viewport — exactly like object-fit:cover, but as a
   real DOM element so guides stay pixel-aligned with the photo.
