/* ==========================================================================
   Estate Planning Intensive — shared stylesheet

   Direction: "The Annotated Draft." The look of working documents — ink-black
   rules, a highlighter, a ballpoint pen, a redline, docket-style mono for
   dates and labels, and § markers. Distinctive, a little playful, still
   plainly professional.

   Retune the whole site from the tokens in :root.
