/* MeshVault shared shell: the one header (nav island) and the one footer.
 *
 * Every public page carries the same <nav class="mv-nav"> and <footer class="mv-foot">,
 * stamped by scripts/sync-shell.mjs. This file is their only stylesheet, so it has to
 * hold up next to three page stylesheets: assets/site.css (marketing), docs/docs.css
 * and legal/legal.css. Those ship element and .brand rules of their own, so every rule
 * here is scoped under .mv-nav / .mv-foot and sets the properties it depends on
 * instead of inheriting them.
 *
 * Colours mirror the bound Figma variables in assets/tokens.css (file
 * 2olO3EZ32oJjauaAqYjLUk, page "01 · Tokens"). Layout follows the header and footer
 * compositions of Figma's Simple Design System (github.com/figma/sds,
 * src/ui/compositions/Headers + Footers): inline links on desktop, a menu button
 * that opens the same links as a column at tablet width and below, and a footer of
 * a brand column plus titled link lists that tighten on small screens.
 * Type is Inter only, per the Figma lock.
