/* The shared stylesheet — one file, no framework, no build step, no external
   fonts, no JS. Referenced by every page as /assets/style.css.

   Colours are tokens ONLY. The :root block below is the neutral fallback so
   this file works on its own; build.py appends the domain's own palette from
   config theme + site.json as a later :root override, which is how a site
   gets an identity without a second stylesheet or a per-page style attribute.
   Never hardcode a colour anywhere else in this file.

   Design notes: this is a reading site for people who arrived from a search
   result with one question. So the measure is narrow, the type is large, and
   photographs are allowed to break out of the measure because on a travel site
   they carry as much of the answer as the prose does. */
