/* ==========================================================================
   AgentOS — design system
   Direction: dark navy ground, violet accent, glass surfaces, large radii,
   Golos Text set large at weight 500 with tight tracking.

   Accent note: the violet accent sits hue-adjacent to the blue chart series
   (normal-vision ΔE 11.1 — under the 15 floor). Resolved by placement, not
   hue: the accent never enters a plot, and every series carries a legend
   entry plus a table view. Do not use --accent as a series colour.
