   1. Fonts
   Every face is self-hosted from /assets/fonts. Gretha (Envato) is the
   display serif for h1 and h2; Cormorant Garamond is the shipped fallback
   if a Gretha file ever goes missing. Voire (Envato) is an alternate display
   serif, declared but unused: swap --font-display to --font-display-alt in
   the tokens block to try it. Kross Neue Grotesk (Envato) is an optional
   body grotesk, declared but unused: swap --font-sans to --font-sans-alt.
