/* AVstackr Blueprint modal — the shell the Proposal, Estimate and Executive Summary modals share.
   ========================================================================
   A plain stylesheet rather than a scoped .razor.css, because scoped CSS is per-component by
   design and this vocabulary is deliberately shared across several. Every class is `bp-` prefixed
   so it cannot collide with Bootstrap or with a component's own scoped rules; a modal keeps its
   own prefix for the parts only it has.

   Every colour is an --app-* token from themes/theme-base.css, so the whole family follows the
   app's theme with no [data-bs-theme] rules of its own. No new hex.

   Three type tiers and no web fonts. The designs name Barlow Condensed, Barlow and IBM Plex Mono;
   the app loads none of them and has no Google Fonts link, so the display tiers inherit the body
   font and carry their weight through uppercase casing and letter-spacing, which is what was doing
   most of the work anyway. Only the mono tier needs a real family and the system stack covers it.

   Radius is 2px everywhere. Status pips are the only circles. One shadow, on the modal.
