/* Venue Acoustic Calculator — "Klangregie Reference"
   Ported from the Squaresmile Design "VenueAcousticCalculator" bundle.
   Scoped under .vac-tool — sits inside the .dash chrome. Bridges the
   existing class names (.calc-card / .top-bar / .tab-bar etc. that the
   17-file JS app binds to) into the new visual treatment so we don't
   have to touch element IDs or handlers.
