================================================================================
Post Card Component (Shared)
================================================================================

Single shared component for blog post cards with variants: featured, default,
compact. Uses PostView for normalized access. All links use p.href (includes
baseurl for GitHub Pages / subpath deployment).

Usage:
  {{ post_card(post, variant='default', show_image=true, show_excerpt=true) }}

Variants:
  - featured: larger card, gradient-border-strong fluid-bg, full date format
  - default: standard card, gradient-border fluid-combined, time_ago
  - compact: minimal (title, date, optional excerpt)
