  /* ---------- Typography ----------
     Ghost 6's font picker (Admin → Design → Typography) injects
     `--gh-font-heading` and `--gh-font-body` via {{ghost_head}} when the
     user picks something other than "Theme default". We reference those
     variables here so the picker actually has an effect, falling back to
     Nexus's serif defaults (Cormorant Garamond + Source Serif 4) when
     no override is set.

     Notes:
     - Ghost's picker only covers heading + body. UI / metadata text
       stays on Inter regardless — small chrome shouldn't shift around
       when you experiment with reading fonts.
     - Type scale (--fs-*), line heights, and the drop cap are tuned for
       serifs. Picking a sans-serif body font will work, but the rhythm
       was designed for serifs; expect a different (not necessarily
       worse) feel. */
