/* ═══════════════════════════════════════════════════════════════════════════
   Skalnav — shared site stylesheet (landing redesign 2026-10)

   Two layers in one file:

   1. CHROME — the shared header (.sk-header) and footer (.sk-footer) of every
      marketing page, /industries, /docs and /faq. Fixed dark in every theme.
      Every selector is prefixed .sk- and the chrome carries its own --sk-*
      tokens, so it can sit on top of docs.css (which still themes the docs
      bodies) without either file touching the other.

   2. PAGE — the base of the marketing pages (home, /product, /validation,
      /pricing, /services, /enterprise, /about). Scoped to body.sk-page so a
      docs page that loads this file for the chrome gets nothing else.
      The marketing pages run a FIXED light/dark rhythm (dark hero, light
      body, dark film band, light proof, dark CTA + footer) and do not follow
      the stored theme: no theme toggle, no theme-boot.js.

   Page-specific CSS (the moved sections) stays inline in each page, as the
   home page always kept it. The legacy token names (--cyan, --white, ...) are
   defined here so the moved section CSS renders as it did in the light theme.

   Cache: .css is 1y-immutable on skalnav.com, so pages load this file as
   /site.css?v=YYYYMMDDx and every change bumps that stamp.
