/* Cardona CT Lab :: Case Sidebar
 * A full-height context rail beside a live tool, for pages where the running
 * UI is the artifact. Reframes the tool as a case study (built for / friction /
 * core system / inspect for) plus proof metrics, instead of a top banner.
 *
 * Token-driven (--c-*), so Day / Night / HC all resolve. Fits the app-shell:
 * the rail is a flex column that scrolls internally like the input/output
 * panels, so the page itself never scrolls at desktop width.
 * Accent edge squared per the portfolio accent-edge rule (left accent stays 0).
