/* ============================================================
   COMPONENT: Why Choose Us / Benefits
   FILE: assets/css/benefits.css
   Depends on: benefits.html, benefits.js
   Loaded after partners.css (Phase 1.0 §6, in build order).

   Global Card System: `.surface--solid` (surfaces.css) supplies
   the card's white background, hairline border, radius and
   resting shadow. Only card-specific layout (icon badge, internal
   spacing, hover/focus) is added here, scoped under
   .benefits__card — nothing here redefines the surface system
   itself.

   Section background is plain white, alternating back from the
   light-gray Partners band above it — the same white/light-gray
   rhythm Statistics -> Partners already established.

   Stage 5.10 correction (Correction #3 — Navy visual rhythm):
   this section's background is now the same navy/gold gradient
   Hero already uses (surfaces.css's .surface--gradient formula,
   copied here rather than referenced as a class so component CSS
   load order can't silently override it) — one of three strategic
   Navy breaks introduced on the Homepage, not a new color system.
   Heading/subheading text below is switched to white/near-white to
   stay readable on navy; every card keeps its existing opaque
   white .surface--solid treatment, so in-card text and icons are
   unaffected and still meet contrast requirements.

   Hover pattern: values copied from buttons.css's secondary/
   primary hover treatment (border-color: var(--color-navy),
   background tint, shadow escalation, a small lift), the same
   convention partners.css already uses — no new hover system.
