/* T20 Exchange (t20xchange.net) — panel-replica, keyword-led build.
   DELIBERATELY different from the other T20 domains: this one is thin,
   login-card first, and keyword dense, modelled on how the top-ranking
   navigational pages in this SERP are actually built.
   Scope note: this treatment applies to t20xchange.net ONLY. */
