/* ============================================================================
   SortedResearch marketing stylesheet — the shared chrome and content blocks
   for every static page in public/*.html. THE single place to edit the site's
   nav, buttons, hero, section headers, cards, CTA band and footer.

   Colour comes from /brand-tokens.css (linked before this file). This file owns
   layout, spacing, radii and type for the marketing surface. Non-colour design
   tokens (spacing/type/radius/shadow) move into brand-tokens.css in a later
   phase; until then the canonical values live here.

   Each page still carries a SHORT inline <style> AFTER this link for rules that
   are genuinely unique to that page (custom diagrams, one-off content blocks).
   Because the inline block loads later, a page can override any default here.
   Add a shared component HERE, not into one page.

/* ============================================================================
   Marketing theme skins — mirror the app's runtime themes (globals.css
   [data-theme]) against the marketing tokens, so the static site can re-skin
   the same way. Activate on a page by setting the attribute on <html>:
       <html lang="en" data-theme="aurora">
   With no data-theme the default brand look above is unchanged. Colour, radius
   and shadow re-skin; headline fonts stay Poppins here (the serif/grotesk theme
   fonts aren't loaded on the marketing pages). These live in marketing.css (not
   brand-tokens.css) so they never reach the app, which owns its own theme set.
