/* Graph My Keywords — design system
   Near-black instrument surface. One chromatic accent, a four-step surface ladder,
   hairline rules. Display type is Geist at 500–600 with negative tracking; data is
   set in Geist Mono with tabular figures. Palette and rhythm follow the Linear
   system (design-md/linear.app), adapted to this product's two accents:

     - Marketing chrome is single-accent lavender, per Linear's rule.
     - The tool's graph, legend and intent chips keep a functional categorical
       palette. Those colours carry meaning (intent, opportunity, topic family),
       so Linear's "one accent" rule does not apply to them — a data palette is
       not decoration. See --data-* below. */
