/* ============================================================
   Trade-content visibility — driven by .stage-inner[data-active-trade]
   ============================================================
   All four trades' content lives in the HTML (good for SEO). Only the
   variant matching the active trade renders. data-active-trade lives on
   .stage-inner because it must be a common ancestor of both .scene
   (containing the videos + tabs) and .float-cards-layer (containing the
   spec-chip, live-card, and doc-preview cards).

   Specificity note: the hide rule must beat .spec-chip .spec-list (0,0,2,0)
   and .live-card .lc-list (0,0,2,0). Scoping to .stage-inner brings the
   hide rule to (0,0,2,0); source-ordered after, it wins. The show rules
   are (0,0,3,0) — they win over both.

   `display: revert` reverts to UA defaults, not to the suppressed author
   rules — so the lists (which were display:flex) and the doc-page-link
   (which was display:block) each need their original display value
   restated explicitly. Inline-by-default elements (spans) ride the
   generic show rule. */
