   markers at slightly different offsets per engine (and per scale), and even
   ::before font glyphs carry font-specific side bearings, so a padding(text)-
   based alignment of the bullet column with the heading text can never be
   pixel-exact everywhere. Instead we DRAW the markers as CSS boxes in
   absolutely positioned li::before rules. Geometry (all values in the item's
   own font size, so the hierarchy scales with the 0.8em per-level sizing):

   - item text starts at (list left edge) + 0.65em
   - the marker box starts exactly at the list's left edge; on content
     slides that edge coincides with the heading text's left edge, i.e. the
     bullet column is flush with the slide title, deterministically in every
     browser and at every window size

   For nested lists the ::before offset is divided by the 0.8 font-size factor,
   because the list's padding is computed in the PARENT item's font size while
   the ::before offset is computed in the (smaller) child size. */
