/* ==========================================================================
   Capeway — Aviation, "First light"
   --------------------------------------------------------------------------
   A second service line with its own register. It opens on an airliner at
   twilight that the scroll flies overhead, climbs into a daylit sky, and
   comes back down to a flight plan.

   It keeps the site's chrome (masthead, index, footer, WhatsApp) and its
   two hard colour rules, which it turns out a flight deck already obeys.
   On an Airbus display, cyan is what the pilot can select and green is a
   state the aircraft reports. So here, as everywhere on Capeway, cyan is
   every action and sage is status only — the instrument readouts, the ticks
   on the checklist, the route. There is no orange on this page at all: the
   site's saffron is re-pointed to a cool cyan-white for the shared chrome.

   Type, chosen by the client from three set side by side: an editorial
   serif, the register of an airline's first-class advertising rather than
   a flight school's brochure. Instrument Serif for headlines, with its
   italic for the one phrase that matters; Geist for reading and controls;
   Geist Mono for every label and cockpit readout. Arabic headlines are
   Amiri, a Naskh with the same book-serif manners; Arabic reading stays in
   IBM Plex Sans Arabic like the rest of the site.

   Everything that moves is enhancement. Without JavaScript, or with
   reduced motion, the page is a plain, complete, readable page: the pins
   collapse, the scrubbed text is simply there and the checklist is ticked.
