/* ============================================================
   ADAPTIVE CARD ISOLATION
   The prose rules above use !important on element selectors
   (table, th, td, h1-h6, p, ul, a, code …) which beats inline
   styles set by the Adaptive Cards JS renderer.  The rules
   below use a higher-specificity ancestor (.ac-adaptiveCard)
   to restore neutral values for each affected element type.
   IMPORTANT: do NOT add "color: initial !important" here –
   that would override the renderer's own inline style="color:…"
   attributes, making light-on-dark text invisible.
