/* ============================================================
   Document Studio - shared design for the document creator tools
   (invoice, quotation, contract, biodata, CV). Prefix .dst-.

   Each tool page sets --dst-accent / --dst-accent-2 on .dst and adds
   its own stylesheet for the paper templates (.dst-paper .tpl-*).
   The site template gives bare <section> 60px padding and clips
   overflow, so the studio uses divs throughout.
