   SADER — s-publications
   Louis-Vuitton-style editorial product showcase for the legal library.
   A masked, scroll-snapped horizontal shelf of book covers framed on a
   parchment mat, with serif titles + faint captions and a brass caption rule
   that draws in on hover. Light (ivory) world; reuses semantic tokens only.
   Loaded AFTER components.css. Logical properties only — RTL flips for free.
