   The logo's amber (#FCAA17) replaces the TecRoot blue. Amber is too light for white text, so text ON it
   uses a dark ink (--tc-on-primary) and text IN brand colour uses a deeper amber (--tc-link, 5:1 on white).
   Neutrals turn warm-charcoal to sit with the amber; status colours keep their meaning. */
