/* ==========================================================================
   PTI COMPONENT LIBRARY - C2 "Hardened"
   Version: 3.0.0

   Content components restyled to the C2 design system (c2-base.css tokens).
   CLASS CONTRACT: 329 published posts emit these pti-* class names.
   Restyle only - NEVER rename or remove a class.

   Loads after c2-base.css (which owns tokens + .pti-content table base
   styles + the table buy-button rules). This file covers the component
   wrappers and the .entry-content legacy container variants.

   Components:
   1. pti-quick-pick     - Top-pick comparison table
   2. pti-pros-cons      - Two-column pros/cons box
   3. pti-spec-table     - Per-product 2-column spec table
   4. pti-comparison     - Full product comparison table
   5. pti-faq            - FAQ section wrapper
   6. pti-buy-links      - Where-to-buy retailer table
   7. pti-disclosure     - Affiliate disclosure box
   8. pti-related        - Related articles section
