Drill: Sidebar nav: collapsible sidebar with 3 sections, badges, icons+labels, collapsed tooltips, active state. Must work at 240px and 48px widths.
Interpretation: Building a regional rail operations duty-officer console (Meridian Rail Control) — warm paper canvas, sidebar one luminance step darker, single indigo accent reserved for active state only, semantic colors strictly for status with shape+color dual encoding. Constraints added: full three-state matrix (240px expanded with 34px rows, 48px collapsed rail with corner severity dots and state-carrying hover tooltips, 264px mobile drawer with 44px targets), persisted collapse via localStorage, bracket-key toggle, and a describe-first dataset so nav badges, KPI strip, table, and footer all reconcile from one source array.
