/*
  Pet Shark Productions - site stylesheet. Plain CSS, no build step.

  Design: an editorial index. Archivo (self-hosted, assets/fonts) for everything, hairline rules,
  small corners, and the logo's light blue used as one deliberate field rather than everywhere.

  The page has a fixed Pet Shark frame (top bar, footer) and a "stage" in between. A project page may
  re-colour the stage through the custom properties below, which _layouts/default.html sets from the
  page's `theme:` front matter; it may also tint the top bar (`theme.bar`, light colours only, because
  the logo's navy outline has to stay visible). All text sits on --surface. See AGENTS.md ("Themes").
