/* Ascenvo Oral Board Trainer — precision-instrument styling (2026-07-06).
   Same design system as the PSR Daily Report Generator / Supervisor Docs
   family of tools: blue/grey identity, typographic panel titles with
   numbered step discs, quiet white cards, system fonts only.
   No frameworks, no external fonts — runs entirely off file://. */
