/* Edition chooser — Far Horizon Group page chrome.
   Token names and values follow the far-horizon-group-web brand stylesheet
   ("dawn at altitude": deep navy, gold as the only accent, serif display over
   system sans) so the door reads as FHG's, not as either app's.

   That site is deliberately dark-only. This page is not: it is the first thing
   a pilot sees on a machine we know nothing about, so it answers
   prefers-color-scheme in both directions with one palette translated, not two
   designs. Mobile-first — the tiles stack, and only widen into a row when
   there is room for two. */
