/* ==========================================================================
   evakeiffenheim.com — one page, one invitation.

   Type system (two roles, never mixed):
     Literata (serif)  — everything that is read: prose, quotes, names.
     Inter (sans)      — everything that is scanned: labels, years, links,
                         form UI, captions.

   Layout system:
     One reading column (--col) for all text. On wide screens the section
     labels (kickers) sit in the left margin, like notes in a book.

   Palette (fixed, from the brief):
     Porcelain #FDFFFC · Jet Black #172622 · Muted Teal #77AE7F
     Slate Grey #6E8387 · Powder Petal #F0DDD1
   Derived ink shades for WCAG AA at small sizes:
     --teal-ink #4E7A57 · --slate-ink #5A6B6E · --mist #AFC3BD (on Jet)
