/* ============================================================
   Votenir site header — shared by every static page (marketing, blog, guides, legal)
   so the header is identical everywhere:
     Votenir · Retrospectives · Estimation · Product Guide · Blog · [Sign in] [Start free session]
   The homepage renders the same header from React (src/components/MarketingNav.tsx). Sign in /
   Start free session open the homepage's Clerk dialog via /?signin=1 and /?signup=1.
   Self-contained (own tokens, font, resets) because the pages load different stylesheets.
   ≤900px: the links move into a "Menu" disclosure (<details>, no JavaScript needed);
   ≤480px: Sign in moves into that menu too, as on the homepage.
