/* ═══════════════════════════════════════════
   VIKINGS — microsite base styles.
   Typography and colours are the sites' own (landing-header.css supplies
   --gold, --white*, --f-heading, --f-body, --f-ui, --nav-h): Inria Serif
   headings, Fira Sans text, the gold accent, the near-black page with its
   violet glow. The layouts follow the design mockups; the branch and
   event-type colours are the dataset's.
   Sections: tokens · base · shared blocks · page frame · cards and grids
             · badges, tags, tables · sources · footer · responsive
   Class prefix: vk-   (the map's own overlay classes are vkm-*, scoped in
   vk-map.css; the timeline's are vkt-*, in vk-timeline.css)
