/* Layout: one calm instrument panel. Header with controls, a strip of six
   concentration tiles, then structure now (ring + tier table), the trend,
   the change matrix, movers and the holder table. Cards only where a chart
   or table needs its own surface. */

/* Colors: one green family taken from the Pepecoin logo (OKLCH hue 150), muted. Tier ramp and the
   single series were run through the dataviz palette validator in both themes. Up/down is green vs
   purple so it survives red-green colour blindness. Neutrals match the fact pages. */
