/* ============================================================
   7. AD PLACEMENT ZONES (Raptive / AdThrive compatible)
   ============================================================ */

/*
  Ad Zone Strategy (aligned with SEO team's Raptive integration):
  ================================================================
  Uses both .ad-zone design classes and .adthrive-* integration classes.
  The .ad-zone classes handle visual layout; .adthrive-* classes are
  Raptive's hook for injecting ads. Both can coexist on the same element.

  Zones:
  1. .ad-zone--header      Header leaderboard (728x90 desktop / 320x50 mobile)
  2. .ad-zone--in-content   In-content ad between sections (300x250 / 336x280)
  3. .ad-zone--sidebar      Desktop-only sticky sidebar (300x600 / 300x250)
  4. .ad-zone--post-result  After tool results/output (300x250, lazy)
  5. .ad-zone--footer       Footer leaderboard (728x90 desktop / 320x50 mobile)
  6. .ad-zone--in-feed      Between recipe cards in feed view (300x250)

  Rules:
  - NO ads inside interactive tool areas (inputs, sliders, timers)
  - Max 1 ad per viewport height on mobile
  - Min 250px content between ad slots
  - All zones have min-height to prevent CLS
  - Sidebar ads desktop-only — never overlap mobile
  - Tool pages use 2-column grid on desktop: tool + sidebar ad
