/* =========================================================
   BRAINTISA — style.css
   Concept: "the yellow t". In the logo one letter is yellow; on
   the site yellow is used the same way, as a highlighter on the
   one phrase that matters in each heading, and as a solid card
   the presenter steps out of. Everything else stays white and ink.
   Light theme only, by design.
