   Design system: GESTALT IN ORBIT
   --------------------------------------------------------------------------
   Every layout decision in this file maps to a Gestalt principle. The same
   rules are repeated on every page so visitors learn them once:

   SIMILARITY ........ one colour = one meaning, everywhere
                       violet  (--state)  -> "you are here / selected / live"
                       cyan    (--link)   -> connections, lines, paths
                       coral   (--act)    -> actions (primary buttons)
                       filled node = work · hollow ring = training
   PROXIMITY ......... --gap-in (tight, inside a group) vs --gap-out (wide,
                       between groups). Labels hug what they label.
   COMMON REGION ..... .region — one enclosure per group of related things
   CONNECTEDNESS ..... constellation nav, flow steps, timeline
   CONTINUITY ........ .sec rail: a single vertical axis runs through pages
   CLOSURE ........... broken rings (.node, logo, hero orbits, sliced word)
   FIGURE / GROUND ... starfield ground, bright figures, one focal action
   COMMON FATE ....... parallax star layers + route satellites move together
   PRÄGNANZ .......... circles and lines only; no ornament without a job
