/*
  Gordie's Field Book: shared styles for every page of gordiesfieldbook.com.

  - No web fonts, no third-party assets, no inline styles anywhere in the HTML.
  - CSP: /delete-account/ is served with default-src 'none' (no images or fonts;
    style-src 'self'). Rules that load an image with url(...) live only on classes
    that page never uses: .hero, .page-hero--art, .section--topo and .cta-card.
    Gradients are not image fetches, so they are safe everywhere.
  - Palette: spruce #17443a, cream #f9f2e3, blaze orange, lake blue, maple amber.
    Blaze and amber are for graphics only; text uses the darker "-ink" variants.
