/* ==========================================================================
   About — compare option about-intro:c, complete USA + India maps
   (site/about_atlas.py, js/about-atlas.js; outlines assets/v2img/aboutatlas.json)

   Light section, same intro as option a. One clay slab, two map panels of
   equal height (USA with Alaska + Hawaii insets | India's official outline).
   Land = a soft bronze tint with a fine dot grain and a thin deep outline,
   raised a hair off the slab. Pins are HTML (fixed px at every width):
   HQ = large deep dot + ring, office = deep dot, worked = hollow ring.
   Tokens only, so html[data-theme] (bronze / blue / soft blue) reaches
   every colour.
