  SWITCH_ - INDUSTRIAL MINIMALIST BRUTALIST DESIGN SYSTEM (BLACK & WHITE)
  Engineered according to:
  - industrial-brutalist-ui: rigid grids, monolithic typography, monochromatic substrates, 90-deg mechanical precision
  - better-layout: balanced negative space, responsive breakpoints, content edge-to-edge alignment
  - better-typography: tabular figures, clear hierarchy, micro-telemetry labels
  - better-ui: tactile button states, custom scrollbars, high-contrast inverted active states
