/*
  NAVIG shared UI layer. Loaded by every app page via templates/_nv/head.html (last in <head>).
  One accent, one radius, one type family, light + dark. Matches the homepage (index.css).

  Contract for page CSS:
    - Use the --nv-* tokens instead of hard-coded colours, radii and fonts.
    - Opt a page into the base look with <body class="nv">.
    - Shared chrome: templates/_nv/bar.html (top bar), templates/_nv/foot.html (content pages only).
    - Full-viewport apps (maps): use height: calc(100dvh - var(--nv-bar-h)) under the bar.
