/* AutoWorkFlowGuided - frontend styles
   Design intent: a worksite instrument panel, not a SaaS card kit.
   The chrome stays deliberately neutral so each tenant's accent colour is the
   only strong hue on screen. Layout is a central responsive workspace with a
   horizontal section rail - never a permanent sidebar. */
