/* OCAIL owner dashboard.
   Layout and type: dark sidebar, cream page, IBM Plex Sans / Plex Mono, yellow active item.
   Chart colours are the validated default data-viz palette: Shift A = slot 1 (blue), Shift B = slot 2
   (orange), as on the Excel Dashboard tab; sleeper types take slots 3-6 so they never read as a shift.
   Target is neutral ink, dashed. Status colours (good / critical) always come with an arrow and a word. */
