   Emillie de Keulenaar — personal site
   Minimalist. White ground, monochrome, no boxes, no accent colour.
   Hierarchy comes from weight, scale and grey — not from rules or fills.

   Body: ABC Otto.  Display: Test National.

   NOTE ON TEST NATIONAL: the trial cut ships only
   [A-Z a-z 0-9 space comma period hyphen].  Never set text in it that
   contains accents, apostrophes, colons, ampersands, em dashes or
   parentheses — the browser falls back per glyph and the line breaks apart.
   Everything with real punctuation is set in ABC Otto.
