/* ── 30. AD ZONES ──
   Centralized, policy-compliant ad placement system.
   Rules this component enforces by design:
   1. Never sits adjacent to a .btn / interactive control (min 40px clearance
      enforced via the required margin below).
   2. Always visually labelled "Advertisement" so it can't be mistaken for
      editorial content or a navigational element (Google Publisher Policies:
      ads must be distinguishable from content).
   3. Reserves a min-height before the real ad script loads, so the layout
      doesn't shift under the user's cursor when the ad renders (shift =
      accidental-click risk, and also a Core Web Vitals / CLS problem).
   4. Only three placement classes exist site-wide. Do not invent new ad
      positions per-page, if a new placement is needed, add a class here
      first so every page stays consistent and auditable.

   Usage: drop one of the three <div class="ad-zone ad-zone--X"> blocks
   (see /ad-zone-snippet.html) at the matching HTML comment marker on each
   page. Never place inside .tool-actions, .btn-group, or within 2 sections
   of an interactive form control.
