/* ============================================================
   Pengqi — Global Reach (world map)
   ------------------------------------------------------------
   Layout idea adapted from the `pengqi-global-map-why` prototype,
   rebuilt on this site's own design tokens so the band reads as a
   native section rather than a pasted-in widget.

   Deliberately inherits from pq-global.css:
     .pq-container   - same 1280px grid as every other section
     .pq-kicker      - same eyebrow, incl. the orange rule
     --pq-navy / --pq-blue / --pq-accent - same palette

   Class prefix is .pq-wm- (world map) so nothing can collide with
   the existing .pq-* site classes or the prototype's .pqg-*.
   No external fonts, no map tiles, no libraries.

   Contrast note: the first pass tinted the land with
   rgba(255,255,255,.055) over a dark card, which measures about 1.15:1
   against the ocean - indistinguishable, and the reason the map read as
   an eye-straining smear. The land fill below is a solid slate tone at
   roughly 2.5:1, with a bright coastline stroke, which is what actually
   makes the shapes readable.
