/* ============================================================
   Pengqi — Why Pengqi
   ------------------------------------------------------------
   Light section that follows the navy Global Reach band, so the page
   alternates rather than running two dark sections together.

   Inherits from pq-global.css:
     .pq-container / .pq-kicker / .pq-btn / --pq-* tokens
   Class prefix .pq-why- so nothing collides.

   On the copy shown here: the prototype shipped this section with its
   own design rationale as body text ("a stable company history is a
   meaningful trust signal..."). Those lines are notes to the site owner,
   not something a buyer should read, so the blocks below carry real
   customer-facing copy instead. See why_* keys in application/lang/.
