/* Shared top chrome (logo lockup, language dropdown, social icons, Log in /
   Create account pill) and footer (tagline + nav) used by every inner page
   (about, pricing, terms, privacy) — one copy instead of four, injected by
   chrome.js into each page's <header id="chrome-header"> / <footer
   id="chrome-footer"> placeholder. Matches aquara.ai's own homepage header
   exactly (fixed 72px height, flat 48/20/16px responsive padding).

   Each page maps its own color tokens onto the --chrome-* names below,
   right after its own :root block, e.g.:
     :root {
       --chrome-text: var(--text);
       --chrome-muted: var(--muted);
       --chrome-muted-strong: var(--muted-strong);
       --chrome-line: var(--line);
       --chrome-accent: var(--accent);
     }
   (terms/privacy map from --card-text/--card-muted/--card-muted-strong/
   --card-line/--success instead.) --body-font is already the same
   variable name on every page, so it's used directly, with no --chrome-
   alias needed. */
