/* ===========================================================================
   dgm-* — reusable Qdrant-style diagram system (static HTML/CSS, no JS).
   A small set of composable primitives + two layout helpers. Every diagram is
   a <figure class="dgm" role="img" aria-label="…"> with a <figcaption>; the page
   prose/tables carry the full meaning, so the diagram is a visual aid.

   Primitives:  dgm-stage (soft rounded layer container) · dgm-stage__title /
   __sub · dgm-card / dgm-cardset (white inner nodes) · dgm-conn (connector band
   + arrowhead; --v vertical, --up, --dashed; dgm-conn__label rides the arrow) ·
   dgm-noeffect (red ✗ "no effects" stub) · dgm-legend / __item.
   Tone modifiers dgm--{blue,teal,green,amber,red,violet,slate} each set two
   locally-scoped vars (--dgm-soft fill, --dgm-edge border/title/arrow) from the
   :root token pairs, so no hex is hardcoded and the legend can't drift.
   Layout helpers:  dgm-gauntlet (inputs → gate → gate → pass, drop-offs below
   each gate, via grid so alignment never drifts) · dgm-stack + dgm-core-rail
   (vertical layers with a nested child). Other pages can reuse all of these.

/* ===========================================================================
   Diagram brand skin — clean, robust, legible, in the website prism palette.
   The dgm-* geometry above is unchanged (grid alignment + compact mono labels,
   so nothing overflows or clips). This only: (1) seats each figure on a faint
   warm panel with a signature iridescent prism rule across the top, (2) retones
   the palette a touch bolder than the chips so diagrams read as EvalGlass rather
   than a default flowchart, (3) thickens the arrows so they read clearly.
   Semantics preserved: green=pass, red=fail, amber=blocked/proposed, blue=info,
   mint=EvalGlass/measure, orchid=accent, warm-grey=neutral. */
