/* =========================================================================
   Ludic Media Studio — v2 Strategic Visualization (v2/strategic-visualization.html)
   Loaded on that page ONLY, after sections.css, audience.css and site.css,
   via V.page(..., css=["css/strategy.css"]) in
   _build/build_v2_strategic_visualization.py.

   What lives here: the page's signature block, "From deck to map" — a slide
   sorter (before), a drawn arrow, one map with numbered pins (after) and the
   key that explains each pin. The pins and key items carry audience.js's
   data-ax-mark / data-ax-stage hooks, which add .is-on to both on hover and
   focus; with no script the pins are plain links to the key.

   Same rules as every stylesheet here: no ID selectors, only the documented
   breakpoints, black / white / yellow pairs only, never white on yellow.
