/*
 * Shared system for dynamically-generated hub pages (pages assembled at
 * runtime outside the Astro content pipeline - today just /fixed-income/,
 * built by sif-nav-updater's FIM pipeline; reusable if a future hub, e.g.
 * gold/alternatives/savings-schemes, is built the same way).
 *
 * See samples/Meta investment navigation review/design_handoff_dynamic_pages/
 * README.md for the full spec. Consumes the --mi-* tokens already defined on
 * :root by header-nav.css (always loaded first, on every page that links
 * this file) rather than redefining any color - the two docs deliberately
 * share one token set (see that doc's closing section, "Relationship to the
 * header handoff"). Brand purple stays the site's real --mi-purple (#693BB8),
 * not the doc's mockup #5b21b6 - same call as header-nav.css, for the same
 * reason (see the plan file / conversation history).
 *
 * Linked from sif-nav-updater's fim_static_templates/base.html with a
 * hand-bumped ?v= cache-busting query param (that repo isn't part of the
 * Astro build, so it doesn't get the automatic content-hash versioning
 * SiteLayout.astro's own links get - bump the version by hand here and in
 * base.html whenever this file changes).
