/* Index Methodology Hub: one stylesheet, no framework. Light and dark follow the system.
   Minimal by design: structure comes from tables (one style everywhere), no shadows, colour
   only for materiality. Breakpoints: < 720 phone, 720-1199 tablet, 1200-1599 desktop (profile
   in two columns), >= 1600 wide (three columns, What changed summary rail). Fluid to 1760px. */
