   depends on the line box and on percentage heights resolving against an
   aspect-ratio-derived frame height — a fragile chain that can letter-box or
   shrink a photo (e.g. the chemical industry tile). Instead the <a> fills the
   media frame as the click target and the img fills the <a>, both absolutely
   positioned, exactly like the category tile already did. The photo can then
   never letter-box, collapse or leave a gap — whatever the file's own
