   Roona — shared design system
   -----------------------------------------------------------------------------
   One stylesheet behind the homepage, the blog and the legal documents, so the
   tokens can't drift between them (they had, in three places).

   Two typefaces, both self-hosted — the privacy policy leans hard on "we don't
   leak you", so the site makes zero third-party requests and this is part of
   keeping that true.

     Fraunces           display only: page-level headings, pull quotes.
                        A soft, low-contrast old-style with a real optical-size
                        axis, so the 84px hero is a genuinely different cut from
                        the 24px article heading rather than the same drawing
                        scaled up. Warm and hand-set rather than luxury-serif.
     Plus Jakarta Sans  everything else: body, UI, and the small caps labels.

   The structural device throughout is the JOURNAL RAIL — a narrow margin column
   holding a label, a hairline, then the content. Roona is a journal; a page of
   dated entries with a margin is what one looks like. It replaces the centred
   eyebrow-over-heading pattern that every section used to repeat.
