/* ============================================================
   MarketPersian CMS v3 — assets/blog.css
   Blog index/single/category + Developers directory + the shared
   post-card component (.mpb-post-card — also used by the
   blog_latest builder block on the home page).
   Theme-agnostic contract:
   - never sets page/body background or font-family (themes own those)
   - neutral semi-transparent surfaces work on dark AND light themes
   - accent = var(--primary) / var(--secondary) (set by every theme)
   - color-mix() lines always come AFTER a plain rgba fallback
   - RTL-first: logical properties only (site is dir="rtl")
   Breakpoints: 1200 / 992 / 768 / 600 / 560 / 400 + reduced-motion
