/* ==========================================================================
   embed.css — LoanCalcNow.com embeddable widget (Priority 4, item 1)
   --------------------------------------------------------------------------
   Compact, SELF-CONTAINED stylesheet for the iframe embed pages
   (/embed/emi.html, /embed/mortgage.html, /embed/personal.html). It cannot
   share the site-wide style.css and stay lightweight, so it carries its own
   small :root token subset (values copied from style.css :root — keep in sync
   if the brand palette ever changes). Light theme only; no @font-face (falls
   back to the host page's fonts / system UI to avoid a web-font request on a
   third-party page). Mobile-first, fluid width.
   ========================================================================== */
