/* ─────────────────────────────────────────────────────────────────────────
   PipelineChart
   Uses project tokens:
     --color-mint           primary mint  #036C4D
     --color-surface-mint   bg mint       #F0F7F4
     --color-border         light grey    #E8E8E8
     --color-display        black         #1A1A1A
     --color-secondary      grey          #666666
     --font-sans            Helvetica Neue / Inter
     --font-mono            JetBrains Mono

   Local fallbacks are provided so the component renders correctly even if
   it's mounted in a context where the global tokens haven't been declared
   (e.g. Storybook, isolated MDX page).
