/* ==========================================================================
   HOW WE HELP
   Homepage services preview: eyebrow + heading + description, a bento-style
   asymmetric grid of 6 service cards (first card featured/larger), closing
   with a compact bridge CTA back to the Financial Assessment.

   Vertical rhythm matches _wealth-section.css (100px / 48px mobile) since
   this section sits in the same part of the page flow. Cards reuse the
   .du-assessment-card conventions (radius-lg, shadow-level-1, hover lift)
   established in _assessment-engine.css, plus a border-color transition
   and icon/arrow hover motion per this component's own brief.
