      S09 is Source Code style [centered asterisk];
      very nice and many permutations, 
      but fails @ mintty per line-height

  Junction         default; not tabular 

    The tabular versions [TOSF] of Old Style Figures allign vertically, as if monospace. 
    Invoke using CSS `font-variant-numeric`. Alternately, regenerate the font, copying the 
    `tosf` glyphs to their respective default number glyphs. Also, copy any 
    changes made there back to the original tablular glyph, so that `font-variant-numeric`
    CSS setting [override] renders same.

    Note on CSS `font-variant-numeric`
    
    `tabular-nums` VERSUS `oldstyle-nums`
    
      font-variant-numeric: tabular-nums;
      font-variant-numeric: oldstyle-nums;
    
    Use `oldstyle-nums`; tends to invoke the tabular glyphs, 
    and is alligned with more typeface designs. E.g., use ...

      body {
        font-variant-numeric: oldstyle-nums stacked-fractions;
      }
