/* gantt.vanagabond — refined-minimal design system
   Direction: literary serif (Fraunces) paired with a tight humanist sans (IBM Plex
   Sans), mono numerals (JetBrains Mono). Warm parchment + deep ink with a confident
   rust accent. Considered motion (200ms cubic-bezier), atmospheric depth from grain
   + soft shadows rather than blunt colors. ──────────────────────────────────── */
