/* Goal Atlas — shared tokens and components.
   Base token set matches the obot report family (executive overview, 2026-07-21).
   Goal hues are the validated categorical slots 1-4, used only in the fixed
   order charts -> app -> autonomy -> keynote so that every on-screen pair is an
   adjacent pair (validated: worst adjacent CVD dE 9.1 light / 8.4 dark).
   Light-mode aqua and yellow sit below 3:1 on the surface, so the relief rule
   applies: every goal-colored mark carries a visible label or letter glyph. */
