/* Ascenvo Audio Study Modules — styling (2026-08-30).
   Same precision-instrument design family as products/oral_board_trainer/
   (navy/steel identity, quiet white cards, system fonts, no frameworks,
   runs off file://) — but built MOBILE-FIRST with oversized touch targets,
   because the use case is a phone on a car mount or a pocket during chores.
   Loaded AFTER ../../css/site.css so these rules win on shared selectors. */
