/* =========================================================================
   SEARCHING FOR SAPPHO — site styles
   Palette: electric aqua on cool near-black. Sleek and contemporary.
   Type: Fraunces (ancient / lyric voice) + Hanken Grotesk (modern voice).
   Signature: the editorial fragment — brackets + lacunae, as in Sappho's
   surviving papyri.
   Note: legacy token names are kept, remapped to the dark scheme —
   --ink/--ink-soft are now LIGHT text; --paper* are DARK grounds;
   --oxblood/--teal are both the aqua accent.
