/* ==========================================================================
   7Fabs Resource Library — page styles.
   Layers on the site's existing /styles.css. Uses only the :root custom
   properties already defined there (--ink, --muted, --line, --soft-line,
   --panel, --surface, --surface-strong, --accent, --accent-dark,
   --accent-soft, --dark-band, --shadow, --shadow-sm, --radius, --radius-lg).

   At merge time this can either be linked as a separate stylesheet or folded
   into styles.css. Every class is namespaced .rl-* so nothing collides.

/* ------------------------------------------------- pre-existing site fixes
   These are NOT resource-library styles. They correct two collisions that
   already exist in styles.css, patched here because this file loads after it
   and the ownership boundary for this job excludes site/. Both should be
   fixed at source in styles.css at merge time and these rules deleted.

   1. `.marketing-site h3` (specificity 0,1,1) is declared AFTER
      `.footer-col h3` (also 0,1,1), so it wins and the footer column
      headings render dark ink on the dark footer band — invisible. This
      affects every page carrying the marketing-site body class, not just
      these. Worth checking the live site.
   2. `.eyebrow a` inherits the global underlined link style, which reads as
      a stray underline on an all-caps label rather than a back-link.
