/**
 * Theme-driven status palettes. Every entry uses semantic tokens
 * (--info / --warn / --success / --destructive) so the colour
 * palette follows the active theme — switching from crisp→nvidia→neon
 * changes which exact hue "approved" renders as, but the *meaning*
 * (success = green, warning = amber, etc.) stays consistent.
 *
 * Keeping the semantic names intentional: they're named after what
 * the status MEANS to the operator, not after a Tailwind palette
 * name. That way the suite works across every theme in the picker.
