/* ============================================================================
   BLOG DESIGN SYSTEM V2 — Shared canonical blog stylesheet
   ----------------------------------------------------------------------------
   Single source of truth for ALL blog article layout.
   Replaces the per-article inline <style> blocks (Article-specific CSS = 0).
   Articles 01-04 all link this file. Legacy FAQ (.blog-faq) and legacy
   Related (.blog-related) markup from older articles is styled identically
   to the current system so every article reads as one template.

   Design goals (user spec):
   - Final CTA -> Footer effective gap ~64px desktop / ~48px mobile
   - Compact Final CTA (no oversized block + huge white void)
   - Identical FAQ / Related / CTA component design across all articles
   - No stacked margins (CTA margin + article padding + main padding)
   ============================================================================ */
