/* ==========================================================================
   west575.org — site stylesheet

   Fonts: Fraunces (headings) — a soft-edged serif with a lot of character
   at display sizes, so headings read as written-by-a-person rather than
   templated. Work Sans (body/UI) — a plain, well-built humanist sans that
   stays out of the way at paragraph length. Loaded from Google Fonts in
   layouts/_default/baseof.html.

   Accent: one color, a warm terracotta/marigold (#d9531e). Picked because
   it reads as a highlighter or a sticky note, not a corporate swatch —
   nothing here is trying to look like a SaaS product or a publisher's
   imprint, just a person's site with one confident splash of color.
