/* ============================================================================
   Shared stylesheet for Ekatra's routed content pages (/how-it-works,
   /security, /privacy, /statement-guides/*).

   The landing page (landing.html) deliberately keeps its CSS inline: it is a
   single-document marketing page where inlining removes a render-blocking
   round-trip on the one URL that matters most. The content pages are the
   opposite case — there are dozens of them, they share one layout, and they
   are cached across a browsing session, so a shared external file is the right
   trade. Tokens below MUST stay in sync with landing.html's inline block and
   with src/lib/data.ts baseTokens.
