/* A diagram drawn over a raster plate (common.schema.json#/$defs/diagram,

   - The plate is black ink on white, so the figure stays in the LIGHT palette
     in every theme. Inverting an engraving for dark mode makes it unreadable,
     and dark-theme overlay colors on white paper lose their contrast. The
     tokens are pinned to literal light values — `var(--accent)` etc. would
     re-resolve to the dark palette and defeat the point.
   - The viewBox is a crop window onto the plate, so overflow is clipped. The
     vector-only figure leaves overflow visible for labels that brush the
     edge; here that would spill the rest of the plate out of the frame. */
