/* nav.css — the site navigation, on every public page (2026-10-02).
 *
 * Brand sheet step 1: one nav everywhere. The markup is navHtml() in
 * src/layouts/Nav.tsx; Layout.tsx, static.tsx and hubs.tsx all render it.
 * The services panel's own look is mega.css; this file is the bar, the
 * dropdown mechanics, the Resources panel and the phone switch.
 *
 * Every selector starts at #nav, and the file loads after every page
 * stylesheet, so it wins over main.css's old indigo pill, home.css's copy
 * (now removed), and whatever a legacy page stylesheet still says. It sets
 * every property those set, ::after included, so nothing leaks through.
 *
 * No :root, reset, body{} or element selector outside #nav: safe beside a
 * legacy page stylesheet (the bar in CLAUDE.md). Colours are the brand
 * tokens in tokens.css.
