/* ============================================================
   Modern / editorial theme  —  SITE_THEME = "modern"

   Design notes, so future edits stay coherent:
   • One typeface. Inter carries prose at 400; labels, years and tags are the
     same face at 600 with wide letter-spacing and uppercase. Hierarchy comes
     from weight and spacing, not from a second font.
   • Strictly black and white: the accent is just the foreground color.
   • Depth comes from hairlines and a single soft glow, never from shadows.
   • Motion is slow and one-directional: things rise 18px and settle.
     Everything uses --ease; nothing bounces.
   • Dark is the default here (see base.html); light is a full second palette.
