/* Product website of Nebuchadnezzar CRM — the look of the website film: a dark, rain-soaked cyberpunk night,
   polished metal and dark glass. The accent colour follows the film's story, chapter by chapter (body[data-ch]):
   1 ignition = cold cyan · 2 the swarm = red alert · 3 escape = electric blue · 4 control = white-blue after the
   shock wave · 5 arrival = sunrise gold. js/site.js sets data-ch; @property lets the colour glide from one to the next.
   Everything is written with logical properties (inline-start / inline-end) so Arabic (dir="rtl") mirrors by itself. */
