/* sth-seam-fix2c: kill diagonal AA hairlines on dark blocks (Club/book/#area neighbours)
   Why seam-fix1 regressed: struct1c put clip-path on #reviews/#offers/#how themselves;
   box-shadow is clipped by that path so the 1px paper seal never covers the fringe.
   Fix: (1) inset the parallelogram 1px so AA sits inside paper / leaves ink gap (invisible on navy);
        (2) 4-dir paper drop-shadow as backup seal; (3) force A5 flats on never-angled blocks. */
