/* Cairn brand styles — per docs/cairn-brand-guidelines.html.
   Palette: Slate #1F2A2E · Stone #6F7A7E · Pebble #C9CFCD · Mist #EDF0EE ·
   Lichen #8FA35D (the only accent). Type: Manrope throughout. Used by the
   standalone Cairn pages (views/cairn/*, views/legal/*) via
   views/legal/cairn-layout.ejs. No inline styles: the Cairn pages' CSP
   forbids them, so spacing tweaks are the small utility classes below. */
