/* COLOUR SCHEME "ocean" (Phil, 2026-10-06: "the hero section of timemator.com is the colour scheme for cloudairtime"):
   deep navy flowing into teal, a bright cyan accent, white headings on the dark parts.
   The purple scheme it replaces is kept in ../themes/purple-2026-10-05.css — to switch back, copy that file over this one
   (and ../themes/favicon-purple.svg over favicon.svg) and run tools/build-site.py.
   The variable NAMES are the old ones on purpose (--purple is "the main colour", --teal "the accent on dark"), so no page markup changed. */
