/* special.css — the "what makes it special" page (/what-makes-it-special).
   Rides on direct.css for the brand tokens and on home.css for the header,
   footer, buttons and section rhythm. This file adds the one thing the page is
   about: a portrait whose details are marked as REGIONS, a veil that takes the
   rest of the picture down a little while one is being looked at, and a card
   that says where that detail came from.
   The same veil answers to the feature list under the picture, so hovering a
   feature and hovering a region look identical — that is the page's argument.
   Light theme only — the warm paper IS the brand (docs/BRAND.md). */
