   Shared stylesheet for the secondary pages (about, privacy, terms, blog,
   /projects/). Brought onto the Keystone Web Systems look in Oct 2026 so it
   matches the homepage: same Harbour navy palette, Fraunces for headings over
   the system stack, light by default with a prefers-color-scheme dark theme.
   It keeps the homepage's constraints (see the top of assets/home.css): flat
   fills, no gradients or glows, no translucency or backdrop-filter, one level
   of elevation, sentence-case labels.
