/* Tuskar dashboard (layer 6), the demo cut (docs/research/2026-10-28-tuskar-demo-story). The PM prototype's styles
   (docs/pm/Control Tower/tuskar-control-tower.html), kept to what the agent view uses.
   Dark by default; light when the system asks for it (REQ-UI-009), or when the viewer
   picks one with the appearance chips, which set data-ui on <html>. Charts are SVG
   coloured through these same properties, so a change of appearance needs no redraw. */

   third-party request and works offline. Latin subsets; Archivo and IBM Plex Sans are variable
   (one file, every weight). SIL Open Font License 1.1: fonts/OFL*.txt. */
