   2. Page wrapper

   Goal: visual distance from the TOP OF THE "M" glyph in
   "FILMS" down to the top of the screen ==
   visual distance from the underline DOWN to the top of
   the grid.

   Top of the "M" glyph in screen coords:
     topbar pad-top                               24
   + center-offset of link in 36px topbar         5.5
   + link's own padding-top                        4
   + half-leading (12 × 1.4 = 16.8 → 4.8 / 2)      2.4
   + Montserrat cap descent inside em-box          ~1.5
   ≈ 37.4 px

   Underline bottom in screen coords:
     link top (29.5)
   + link content height (16.8 + 4 + 4)
   ≈ 54.3 px

   Grid top = underline + 37.4 ≈ 92 px.
