/* ==========================================================================
   Feature card — editorial card for "type cards" patterns.
   Replaces ad-hoc .price-type-card, .rent-card, .factor-card that lived in
   per-page CSS. Single canonical home.

   Anatomy (all parts optional):
     .feature-card
       .feature-card__icon        — outlined terracotta circle, ~36px
       .feature-card__eyebrow     — caps tracking label (taupe)
       .feature-card__title       — Cormorant Garamond, ink
       .feature-card__accent      — large terracotta tabular number (price, %)
       .feature-card__sub         — small descriptive line (taupe)
       .feature-card__divider     — hairline (auto-rendered if details present)
       .feature-card__details     — dl/dt-dd list for fine-grained data
       .feature-card__body        — paragraph copy

   Variants:
     .feature-card--paper         — paper surface (slightly deeper than cream)
     .feature-card--ink           — ink slab with cream type
     .feature-card--compact       — tighter padding for grid density
